Finishing of external slopes on windows. Finishing plastic windows from the outside - types and methods, necessary components and technology of work Options for finishing plastic windows from the outside

When installing a plastic window, as a rule, window hole loses its attractiveness. In this case, potholes, cracks, and remnants of polyurethane foam appear. What to do?

There is a simple way out - to make high-quality external slopes. To do this, it is enough to choose the right installation material and perform work using existing technologies.

Let us dwell in more detail on issues related to the finishing of external slopes.

Purpose of external slopes

A coating inside the window opening that protects the window profile from influence environment, is called a slope. Conventionally, based on location, it is customary to distinguish external and. Although they are parts of the window opening, each has its own function.

The main functions of external slopes include:

• giving glass unit attractive looking. A high-quality window structure should not be adjacent to a broken wall;

• increasing the level of thermal and sound insulation. Without high-quality slopes, it is impossible to create the necessary tightness of double-glazed windows, which means that the room will not be protected from the street;

• protection window box from environmental influences. A high-quality slope protects against corrosion mounting elements design, in addition, the possibility of freezing and fogging of the glass unit is reduced. In any case, a protected window frame lasts longer, which means it does not need to be repaired or replaced frequently.

When installing plastic windows, installers rarely finish the outer slopes at the same time. This work is significantly more expensive than installation and is performed separately.

The sun destroys the foam

Advice!

It is better not to put off finishing the external slopes for too long. Firstly, unprotected polyurethane foam has no strength, and secondly, it will have a bad effect on the condition of the window frame.

About materials

All materials for slopes create their own decorative look and different levels of glass protection.

When finishing, the advantages and disadvantages of materials must be taken into account. Usually for finishing works The following materials are used on external slopes.

1. Plaster mixture.

A long-known method is plastering. The plaster mixture is prepared from different compositions.For exterior work, you cannot use a mixture with gypsum, as it absorbs moisture and then crumbles.

To the advantages plaster mixture applies:

• the ability to cover any surface;

• economic benefit;

• high resistance to moisture penetration.

Owners of plastic windows note the following disadvantages of plastered slopes:

• high labor intensity and duration of work. The solution is applied in layers;

• Low thermal insulation qualities of plaster can lead to freezing of slopes. In addition, condensation may accumulate and fungus may form.

1. Plastic.

Plastic panels have a hollow structure

The material has been successfully used in window openings overlooking a loggia or balcony.

For slopes, sheet plastic or plastic panels are used.

To the advantages plastic slopes applies:

• glossy surface harmonizes with the window profile;

• good thermal insulation qualities if you add insulation;

• a wide variety of color options;

• quick and easy installation with minimal waste;

• long service life.

Plastic slopes have disadvantages:

• poor quality material turns yellow over time;

• the damaged fragment changes completely.

1. Sandwich panels.

Between top layers PVC is expanded polystyrene foam

This is a three-layer panel made of plastic and insulation. When choosing panels, the conditions in which the slopes will operate are taken into account. Thanks a lot color palette, it is not difficult to match the panels to the color of the window profile.

Panel with plastic decorative profiles

Sandwich panels are considered a good choice due to their advantages:

• high thermal insulation qualities reliably protect the window from changes in temperature and humidity;

• environmental Safety;

• quick installation;

• high strength;

• easy care.

The slopes were finished with sandwich panels

The disadvantages of sandwich panels include:

• at low temperatures, color changes and deformation occurs;

• fade in the sun;

• panels are produced large sizes, so it must be cut during transportation;

• If the laying technology is violated, the material may delaminate over time.

1. Metal.

Galvanized steel, coated with special anti-corrosion compounds, is considered the most comfortable material for the formation of external slopes. Due to its special strength, the window opening does not deteriorate appearance for the entire period of its operation.

Such a disadvantage metal slopes, as the high cost is compensated by their advantages:

• high strength. The material is not afraid of mechanical stress;

• wide variety of color coatings. Easy to paint;

• easy care. It is enough to wipe occasionally with a cloth.

The material has minor drawbacks:

• cannot be used in arched window openings;

• If you install it without noise-absorbing tape, then when it rains you will hear the characteristic sound of drops hitting the metal.

1. Styrofoam.

Using polystyrene foam for external slopes has a double effect. Firstly, it increases thermal insulation premises, and secondly, the appearance of the window improves.

In addition to these advantages, such slopes have others:

• quick and easy installation;

• the material is easy to process;

• good insulating qualities;

• light weight;

• the ability to create any color options;

• long-term operation.

Slopes made of this material have disadvantages:

• low strength. The material must be covered with a protective layer;

• poor air exchange;

• destruction when hit by some chemical compositions. The material requires protection and selection of adhesive solutions.

For external slopes it is better to use a type of foam - this is expanded polystyrene, which has a higher density.

Preparing the window opening

External slopes made of any material will be of high quality and beautiful if the opening is properly prepared.

Preparation includes the following operations:

1. Removing damaged and protruding sections of the window opening. This operation is easily performed using a chisel.

1. Cleaning the surface adjacent to the window frame from flaking fragments (paint, whitewash).

Advice!

It is better to remove the protective film on the plastic window after finishing the installation of the slopes.

Plastering instructions

In order for the plastered slope to reliably protect the window unit, several recommendations must be followed:

Plastering work is carried out in the following sequence.

1. In some cases, the lath is removed and then the corner is straightened.

Instructions for finishing with plastic

Before laying the plastic panel you need to prepare:

• wooden slats up to 70 mm wide and up to 15 mm thick;

The work is performed in the following sequence.

Instructions for finishing sandwich panels

There are many ways to install slopes using sandwich panels. The simplest is to install the panels in window opening to "liquid nails".

A more labor-intensive method, but it produces slopes High Quality when installing panels on the sheathing.

1. The sheathing is installed in the window opening using 20x40 mm slats.

1. The side parts are attached in a similar way.

1. A platband is attached to the sides of the window opening.

1. The installation is completed by sealing all joints with liquid plastic.

Instructions for finishing with metal sheets

The process of installing metal slopes is not complicated, but it requires care and precision. To properly insulate a room from the street, it is practiced to place thermal insulation under the sheets.

The work is performed in the following sequence.

1. At the final stage, the top strip is installed.

1. For improvement insulation characteristics sealant is applied to the joints of the structure.

Video instruction:

Instructions for finishing with foam plastic with plastering

Before you begin installation work with polystyrene foam, you need to choose the right adhesive. The adhesive composition ST-85 Ceresit is considered optimal.

The work is performed in the following sequence:

1. The adhesive composition is mixed until it becomes a homogeneous mass, but it should not flow down the instrument.

1. Initially the tide is set. A sheet of foam plastic is placed under it to reduce the noise from the sound of raindrops.

1. The foam sheets are laid from the bottom up, close to the window frame. To avoid voids, the adhesive composition is not saved. Excess glue must be removed with a damp sponge.

1. All cracks are sealed with foam.

1. The top layer of plaster is covered facade paint, which is matched to the color of the building.

Same process in video:

In general, the external slopes for a plastic window can be finished with any material you like. If you do not violate the installation technology, the slopes will last a long time and will not lose their attractiveness.

After replacing the windows, the external openings look unaesthetic, which means they need to be brought into proper shape. It is necessary to finish the window slopes from the outside to make the window look really good.

Why is it necessary to carry out external finishing of slopes?

Do not think that after installing new windows, the renovation work in the apartment will end. Alas, few builders finish the outer part of the opening, and more than 70% of consumers of construction services never finish the work they start, considering it a waste of time and money.

But external finishing of window slopes will prevent serious problems from arising.

Slopes left unfinished are not only unsightly. Over time, untreated slopes will have a detrimental effect on the sealing of openings. Polyurethane foam, even if carefully trimmed, will begin to deteriorate over time under the influence of UV radiation and wind. In a few years, the sun will turn the foam into crumbs, which will slowly but surely fall out of the opening.

As a result, this will lead to strong drafts “settled” in your house. Birds are often interested in polyurethane foam, biting off small pieces of material to create nests. To prevent such serious damage, you need to know how and with what to finish the external slopes of windows.

Options for finishing external slopes: choosing material

Exist various ways give a finished look to the external slopes. Each of them has its own characteristics, characteristics, advantages and disadvantages; finishing options differ in the time of work and the cost of implementation.

Possible finishing options:

• The oldest and most economical option is plastering slopes. The work is quite simple: we dilute the dry mixture with water and finish it. After the mixture has dried, it is sanded and sanded, then painted. This finishing of exterior window slopes is cheap, which is a decisive factor for many. True, there is also a minus here - the duration of the work. On average, finishing slopes using this method takes up to 10 days. The disadvantages include the “coldness” of the slopes: the junction of the slopes with the frames can freeze, which causes condensation to form, leading to the appearance of fungus. If we are talking about plastic windows, then a mismatch between the plaster mixture and PVC profiles can cause a weak connection. As a result, the plaster may soon peel off from the window, which means the work will have to be done again.
  
• Using drywall. Drywall is considered a more modern material for finishing window slopes. Its main advantages include ease of operation and good result as smooth surface, which can be simply painted. However, it should be borne in mind that they will last a long time only if you properly prepare the surface: treat it with antibacterial impregnation. also have disadvantages. The main disadvantage in this case is the lack of moisture resistance and the need for periodic repairs.
• Use of plastic slopes. The most modern way is to use PVC slopes. Due to wide choice colors and technical features, such products will help to effectively design slopes of any shape, including bay windows and arches. In addition, the material of the slope will fully correspond to the material of the window profile (if we are talking about PVC windows), having a similar expansion coefficient at different temperatures. In addition, the material does not develop microcracks over time, fungus will not appear in it, and dirt is easy to remove. Finishing the external slopes of windows using PVC panels has a disadvantage - the rather high cost of the products. However, if you want guaranteed quality, then it is better to choose them, despite the cost.
  
• Siding panels are also often used for finishing external slopes. They are easy to clean and do not accumulate dust on the surface, and are resistant to aggressive influences. external environment, are not afraid of severe frosts and do not fade in the sun. In addition, siding panels can last quite a long time if they are installed correctly.

Having chosen how to finish the outside window slopes, you can begin the work itself.

Finishing window slopes from the outside using plaster

As we have already said, the use of plaster is the most economical option, whereby this method accessible to absolutely everyone. The work is also quite simple, the main thing is to follow our instructions exactly.

How to finish window slopes from the outside - step-by-step diagram

Step 1: Surface Preparation

First you need to clean the window openings - remove all dirt, dust and excess foam. To prevent the solution from getting on the glass, they must be covered with film, and if there are cracks, it is better to seal them.

To apply the mixture you need to use a medium-sized spatula - it is much more convenient if it is no smaller than the width of the slopes.

Apply the mixture from top to bottom, carefully pouring a small amount onto the surface and smoothing it, not forgetting to monitor the level according to the previously installed beacons. In order for the solution to lie on the surface efficiently, try to hold the spatula perpendicular to the surface of the slope. Such actions are performed in several approaches with stops, due to which the surface of the slopes will be smooth and without cracks. If suddenly during the process of work you develop several bumps, it’s okay, because after the plaster has completely hardened, you will need to go over the surface with a grater or sandpaper, which will easily remove errors and unevenness.

But finishing window slopes from the outside with plaster does not end there. To remove any imperfections that may occur during plastering, use putty. The main thing is to apply it after the mixture is completely dry. On average, one centimeter of plaster takes about 5 days to dry, but to be safe, you can wait a couple more days. You should not make a layer of putty too thick - 0.5 cm is enough to smooth out unevenness. Carefully apply the putty with a spatula and level it.

Works such as installing skirting boards and ceiling cornices, finishing of door and window slopes on the side of the premises and on the facade are considered a mere trifle compared to general construction and repair activities. But they are the ones who put the finishing touches and create the finished look of the interior.
But it's not just about beauty. High-quality slopes strengthen the opening, protect it from destruction, and play an important role in the thermal insulation of the building.

After installing the double-glazed window, slopes are installed, the material for the manufacture of which is selected taking into account such parameters as climatic features region, purpose of the room, requirements for appearance and finishing style, practicality, price, etc.
The main selection criterion is which side of the building - internal or external - the cladding is made from. It is clear that not all materials used in rooms with stable temperature and humidity conditions are suitable for finishing windows on the facade of a house.

For interior decoration

Basically, in rooms with normal humidity and constant temperature, slopes can be made from any materials. The main criteria here are appearance, compatibility with the interior, and ease of maintenance.
Most often, the internal cladding of windows is made of the following materials:

• Plastering followed by painting;
• Drywall, plywood, chipboard and other sheet materials, which also serve as the basis for subsequent finishing;
• Tree;

• Plastic sandwich panels;
• Ceramic tile;
• Artificial stone for cladding windows, etc.

It also matters what the double-glazed windows themselves are made of. If they are wooden, plastic slopes can only spoil the appearance of the window and reduce its cost. But the cladding of a plastic window may well be made of sandwich panels or PVC panels.
These same materials, along with smooth tiled or ceramic tiles (see Window tiling - rules for finishing corners and slopes) are the most practical for finishing openings in wet areas or those in which you often have to do wet cleaning and disinfection - in kitchens, bathrooms, hospital wards, child care facilities, etc.

For exterior decoration

Cladding the window opening from the outside reduces the above list of materials by several positions. This primarily applies to drywall and other sheet materials based on wood waste, which is completely unsuitable for use on outdoors.
Under the influence of high humidity, direct exposure to snow and rain, sharp temperature fluctuations, they are deformed and destroyed. Not suitable for exterior decoration and decorative tiles under brick or stone based on gypsum - it is also very afraid of moisture.
On the other hand, this list can be expanded with the following materials:

• Metal. Slopes are made of galvanized steel with colored polymer coating;
• Facing brick or clinker tiles;
• Siding. Or rather, special additional elements intended for finishing openings on facades sheathed with this material.

Note. When choosing an option for exterior window cladding, what the building is made of or decorated with is of great importance. It is hardly appropriate to glue artificial stone on them if the facade is wooden. But metal slopes look great in any combination, provided that the color is chosen correctly.

In general, there are nuances in choosing suitable materials a lot of. For example, if there are no problems with straight openings when installing any of them, then the cladding round windows or openings with arched vaults imposes certain restrictions.
And the choice here is no longer so great - it’s either plaster, or finishing with small tiles, or using flexible materials. For example, drywall, which, when wetted, can be given the desired shape. After drying, the material returns to all its performance characteristics.

For window sills

The lining of the window sill can be made of the same material as the slopes. But it is usually subject to more stringent requirements for strength, resistance to damage and moisture, and other parameters. Therefore, it is not recommended to make it from plasterboard, ordinary plastic, or veneer gypsum tiles.
Today on construction market There are a lot of offers of ready-made window sills, which only need to be adjusted in length and width. They are made from specially treated wood, durable plastic, moisture-resistant MDF and chipboards with decorative plastic or laminated coating.
Cast artificial stone window sills are becoming increasingly popular. They are made individually after taking measurements and selecting the desired shape, and are installed by the manufacturer. The pleasure is not cheap, but, as they say, it lasts forever.

Unfortunately, this option is not affordable for everyone, and besides, if you want to change the interior, you will simply feel sorry for spending a lot of money. But there is another way to decorate the lower part of the window in an original way by installing a figured sawn sheet of durable moisture-resistant material and finishing it with porcelain stoneware or mosaic.
Thus, lined window sills look great, are not afraid of moisture and heavy loads, are scratch-resistant, and are easy to clean. And if desired, the tiles can be replaced during the next renovation.

A window sill is installed indoors and often performs additional functions - countertops, stands for house plants, shelves for small items. household appliances in the kitchen.
And the outer cladding of the window involves installation along the lower edge of the ebb frame - an inclined structural element designed to drain water flowing from the window and protect the installation seam from moisture. The most common material for making flashings is galvanized and painted. polymer paint metal.

In a word, decorative cladding windows these days can be quite varied due to the availability of a huge number of traditional and modern materials. We are also encouraged by the fact that many of them are easy to install with your own hands, achieving not only an aesthetically pleasing appearance of the openings, but also increasing their performance properties.

Framing openings - examples of installing slopes from different materials

If desired, you can handle the work of finishing the slopes yourself, especially if we're talking about about installation of sheet materials. Some difficulty in the absence of practice is caused by plastering, gluing tiles and other “wet” processes.
If the finishing is carried out with elements specially designed for this purpose, then the kit is usually accompanied by detailed installation instructions, following which you can cope with the work without special knowledge and training.

For example, if you do not know how to cover windows with siding, ask the seller for an installation diagram or look for recommendations on the website of a specific manufacturer.

Below we will talk about how to make window cladding yourself using the most common materials - plaster, drywall and plastic sandwich panels.

This finishing option is attractive primarily for its low cost and durability. To work, you only need a dry construction mixture diluted with water.
So:

• The work begins with rough leveling of the surface by cutting off the sagging concrete in the corners, after which it is cleaned of dirt and dust;
• The gaps between the wall and the double-glazed window are filled with mounting foam or tow soaked in a gypsum solution. In this case, it is necessary to leave a gap around the perimeter of the window frame, which will be filled with a solution;
• When these materials are dry, you can proceed directly to the plaster;

Master of Architecture, graduated from Samara State University of Architecture and Civil Engineering. 11 years of experience in design and construction.

The design of PVC windows after their installation includes finishing of the slopes. After completing this work, the corners are decorated with decorative corners or internal slopes are installed on the windows.

Why do you need window treatments?

The interior decoration of plastic windows has not only a decorative function, but also a protective one. The installation seam must be reliably protected from the influences exerted on it so that window system In general, it functioned correctly: the glass did not fog up or freeze, and condensation did not accumulate on the slopes.

The installation seam on the outside must also be reliably protected from exposure to precipitation, wind and sunlight, under the influence of which the polystyrene foam is destroyed. You can effectively protect it by installing metal slopes and trims on plastic windows for exterior finishing, which will give the window a neat, finished look.

For interior decoration For window openings in the house, different types of material are used. This could be decorative plaster, do-it-yourself installation of PVC panels or drywall on the slopes of plastic windows. The finish looks impressive internal slopes decorative artificial stone. To understand which of these methods is better, it is worth considering each of them separately.

Decorative plaster

When carrying out renovations in a house, interior decorative plaster is often used as a finishing material for walls. This material will make the slopes on the windows unusual and spectacular.

Decorative plaster is often used for interior decoration of slopes

Part decorative plaster may contain fillers of various fractions and origins - these can be natural wood fibers or stone chips or artificial granules various sizes. Decorative plaster is used as a finishing layer, creating an unusual textured surface or an intricate design, like Venetian plaster.

As a material for interior finishing of slopes, decorative plaster has the following characteristics:

• effectively masks base unevenness;
• it can be applied to any base material: brick, concrete, plasterboard, wood;
• this material does not absorb odors;
• safe, non-flammable and environmentally friendly composite;
• has soundproofing qualities;
• in case of minor defects in the base, preliminary repairs are not required;
• when treated with wax or painting, the plaster layer becomes moisture-repellent;
• has breathability;
• Repairing the plaster layer is very simple, there is no need to remove all the finishing;
  finishing of arched window structures is possible.

Types of decorative plasters

Depending on the type of filler and main substance, decorative plasters are:

Surface preparation

The durability of the plaster layer depends on a well-prepared surface.. Therefore, finishing window slopes inside with decorative plaster should begin with preparing the base.

Drywall slopes

Finishing slopes with plasterboard is quick and does not require special construction skills. Installation is possible using polyurethane foam or putty as an adhesive or on metal carcass . Drywall for windows must be marked GKLV.

Drywall on slopes can be mounted on a metal frame

It is characterized by the following positive qualities:

• environmental friendliness;
• affordable price;
• simple installation;
• decorative effect when finishing with any materials;
• smooth, durable surface;
• durability;
• possibility of designing arched openings.

Preparatory work

Surface preparation consists of the following steps:

Using polyurethane foam, you can finish a window opening without having any construction skills. It is important to remember that drywall is a fragile material, so cut it out necessary details it must be done carefully, without any effort.

To get smooth edges at the cut points, you need to follow the drawn line on a sheet of drywall, applying a ruler, using a sharp construction knife make the cut. You need to cut the top paper layer and a little inside. Then you can lightly tap along the cut - the drywall will break itself along the intended line.

Foam mounting

Finishing slopes with plastic panels

Finishing of window slopes inside can be done using ceiling plastic panels or multilayer sandwich panels. The installation of this material is so simple that it is possible to finish the inside of plastic windows with your own hands. How to make slopes for plastic windows in a house will be described below.

PVC panels are most often used to finish slopes from the inside.

Sandwich panels are better than ceiling panels due to the presence of a layer of insulation inside. However, ceiling ones also have thermal insulation properties due to air chambers between the internal stiffeners.

Installation and repair of slopes inside a building using these finishing materials is possible due to their qualities:

• PVC slopes are durable;
• the use of panels for finishing window slopes gives them an attractive, neat appearance;
• finishing options can be very diverse thanks to a wide range of colors,
• which have external surfaces of panels;
• it is possible to install plastic on arched structures;
• Repairing plastic slopes is not difficult;
• ease of installation - window openings are finished with your own hands, and installation does not take much time;
• PVC is easy to process;
• slopes lined with plastic on the inside are easy to maintain;
• finishing window openings with this material increases the energy efficiency of the window system;
• The interior decoration of windows prevents them from fogging and freezing.

Installation

How to install internal slopes for windows made of PVC panels is shown below.

• remove excess polyurethane foam using a stationery or construction knife;

  To remove residual foam, use a stationery or construction knife

• We fix it along the perimeter of the window opening near the frame using self-tapping screws wooden block;

  Secure a wooden block around the perimeter of the frame

• We attach the starting profile to the block;

  The starting profile is attached to the block

• We install a strip along the outer perimeter of the window;

  The rail is fixed along the outer perimeter of the frame

• It's better to insert first side elements;

  Side panels installed first

• then insert the top panel, bend it, foam it a little and fix it in required position;

  A small layer of foam is blown between the upper slope and the PVC panel

• fix the side parts in the same way;
• After the structure has dried, the corner parts are decorated with decorative elements - corners or platbands.

  Corners are covered with platbands

Sandwich panels can be installed in the same way or without starting profile. In this case, the panel is placed in a groove cut in the mounting foam. This installation method is relevant when it is not possible to place the block around the perimeter window frame.

Platbands

Platbands or casing for internal slopes for PVC windows can be made from different materials, but its functional purpose one thing - protecting the installation seam from destruction and giving the window opening an aesthetic appearance.

Types of platbands

Platbands differ in appearance and functionality:

Flat platbands. This is the easiest to perform and inexpensive type cashing out.
Profiled platbands have a convex surface of different profiles, aimed at enhancing the decorative function of cashing.
Shaped platbands can have a complex relief and imitate natural wood.
Carved platband is the most expensive type of cash, made to order according to custom sizes.

Materials for production

The most common material for making cash is sheet plastic. It is used for the manufacture of budget flat platbands, which can be used for finishing windows indoors and outdoors.

This material is not afraid of temperature changes, exposure to moisture or sunlight. Its surface can be laminated and acquire any color or imitate various breeds natural wood. Therefore, choosing cash to match the color of the window facade will not be difficult.

Plastic cash can be made to match any façade

Plastic platbands are not prone to deformation due to temperature changes and exposure to moisture.

Profiled PVC trims have the same properties, but may have a shaped surface. They are also used for interior and exterior window decoration.

MDF trims can also be flat or profiled, but they are used exclusively indoors, since the properties of MDF do not allow them to be used outdoors under the influence of surrounding natural phenomena.

For external use, dense foam casing can be used. This material is easy to process and install. You can cut out the most intricate and intricate designs from polystyrene foam. complex shapes. It can be decorated with any finishing materials. It has negligible weight, so it does not put any load on the wall.

Foam trim can be used for exterior window decoration

The most expensive window design option is the installation of wooden carved cash. Carving can be done by hand or mechanized way. Handmade is very expensive due to its individuality and exclusivity.

Profiled and shaped frames made of natural wood, made on a machine, will cost less.

Behind wooden platbands careful care is required, since wood, when used in conditions of exposure to the external environment, has some disadvantages:

• wood can become deformed when absorbing moisture or crack as a result of drying out;
• Such cashing looks harmonious on wooden windows or on timber facades. On modern facades such cashing out will look ridiculous.

Fastening

Most often, when installing platbands on a plastic window, mounting elements are used that are fixed to the frame or wall.

Platband installation diagram

The use of removable trims, which are attached to special latches, allows for quick and high-quality installation.

Hello, my dear subscribers!

I have noticed how often questions have recently been received related to the fact that long-installed plastic windows are gradually losing one of their functions - protection from drafts.

People whose apartments had PVC windows functioning properly for several years began to note with bewilderment that noticeable air movement had appeared in the area of ​​the internal slopes.

It is characteristic that in many cases an examination of the window itself does not reveal any visible reasons: sealing rubber is in good condition, and the window sash pressure is adjusted according to all the rules.

What's the matter?

With a high degree of probability I can say: it’s all about exterior decoration windows, that is, in the construction of external slopes.

External slopes for windows made of PVC profiles

Our citizens are accustomed to the fact that everything should be done by itself, and there is no need to go into deep details in every matter. But practice shows that this approach is fundamentally wrong. Let's take, for example, the question of finishing a plastic window after its installation that interests us.

What does the average consumer pay attention to after the installers have installed the window and the finishers have made the internal slopes? Usually, it depends on how the opening sash works, whether the plastic or glass is damaged, how smoothly and professionally the internal slopes are arranged.

In cases where these items meet the customer’s expectations, he happily signs the acceptance certificate for the finished product

Meanwhile, before making a full settlement with the installer, it would not be out of place to pay attention to the exterior finishing of the places where the window frame adjoins the façade of the building.

If mounting foam is visible between the structure of the window block and the window opening, this indicates a violation of the technology for arranging the junction points.

Means, such a window cannot be used, otherwise not much time will pass, and the customer will again have to turn to specialists for help to eliminate this shortcoming.

And the disadvantage in the form of polyurethane foam that is not protected from atmospheric influences will manifest itself quite soon - internal slopes of plaster begin to freeze and even the appearance of drafts under slopes trimmed with PVC panels or any other piece material.

Polyurethane foam

You should know that Spray foam is not a sealant. Its main purpose is sound and heat insulation, fixing door and window blocks, filling various voids and junction points of installed mounting structures.

Foam copes with such work “excellently” if it does not have a destructive effect on it. ultra-violet rays and wind erosion, that is, if it is protected by other finishing materials that are resistant to such influences.

Polyurethane foam must be present in multilayer system insulation of slopes.

But it should not be visible, because when installing a window unit in compliance with all the rules, the outer junction of the frame and the opening must be covered with a self-expanding sealing tape.

Technology for arranging an external slope in the video:

Protection for polyurethane foam

PSUL (abbreviation for self-expanding tape) is glued to the frame before installing it in the window opening. Within about half an hour (depending on the ambient temperature), it increases in volume, filling the space at the outer junction of the edge of the opening with the window frame.

PSUL tape serves reliable protection polyurethane foam from all possible destructive processes, because it:

• does not rot;
• moisture resistant;
• does not deteriorate from exposure to sunlight;
• has good vapor permeability;
• when expanded, it perfectly fills small protrusions and irregularities;
• retains its protective functions at temperatures from -50 0 to +90 0.

The service life of the self-expanding tape is 50 years and, in theory, its protection is sufficient for external slopes. But, unfortunately, there are no ideal finishing materials.

The PSUL tape also has a minus. It lies in the increased deformation component of this tape. Simply put, it can be easily damaged by simply pressing lightly with your finger.

Therefore, the self-expanding tape also needs protection, and such finishing protection can be the installation of external slopes.

Conditions for finishing external slopes

Some customers, having installed a window and finished the internal slopes, postpone the installation of external slopes “for later” and thereby contribute to the rapid decline performance characteristics the entire window block.

In fact, we can confidently say that External slopes should be installed first. This is especially true in cases where the window is installed at a height, and all work on its exterior decoration can only be carried out from inside the room.

In this case, the finisher will have to work while in the window opening, and such conditions may well lead to damage to the window sill and already finished internal slopes.

Imagine that the design of your plastic window from the street side will consist of plastering the plane of the window opening. How long will the finisher have to work with the liquid solution? And even with the highest qualifications of the worker, the solution, especially if applied to the upper slope, no, no, will end up on the windowsill, no matter how you cover it, and from there on the floor in the apartment or on the sides of the internal opening.

My practice shows that in a situation where in an apartment (where it is impossible to design a window from the street side) the internal slopes were first made “to zero”, and only after that the finishers were engaged in arranging the outer part of the window opening, after all the work was completed, the internal slopes had to be repair.

Therefore, when making a decision on installing slopes around plastic windows, do not ignore my recommended sequence of actions:

• installation of a window unit;
• device for connecting the window structure and the walls of the window opening;
• finishing of external slopes;
• insulation of the surface of internal slopes;
• finishing of internal slopes.

If you follow this plan, you will probably save a certain amount of money, which would have to be spent on repairing already finished but damaged due to a violation of the order of finishing the internal surfaces of the window slopes.

Finishing

The construction of external slopes has a completely different specificity, different from that used when constructing slopes indoors.

When finishing slopes from the outside, you cannot:

• use drywall, because it will quickly get wet and fall apart after the first rains;
• install PVC panels, because Sun rays And low temperatures have a destructive effect on this type of finishing materials;
• use wood parts not treated with a special protective compound;
• use plaster compositions based on gypsum and putty, not intended for outdoor use.

The same as with interior decoration, when, for example, it is impossible to plaster the slope if inside the room around the window opening - wooden frame, the choice of exterior finishing largely depends on what building material the façade of the building is made.

Finishing material

There are practically no questions when installing the external slopes of a building on the facade of which plastic or metal siding is installed.

In these cases, the slopes are formed with special shaped elements (slope strip, window drains, complex finishing angles), which are included in the set of external façade finishing with these materials.

The situation is somewhat more complicated with the choice of finishing material for the installation of external slopes log house because they already exist here different variants, and you need to choose one that will not spoil all the beauty of natural wood.

If the plastic window is installed in the same plane with the outer surface façade wall, then its design does not present any special difficulties. A casing of the required width is installed at the junction, and this is enough to preserve the aesthetic appearance and the space that can be affected Negative influence atmospheric phenomena, was protected from them.

But usually a plastic window is installed in a recessed slope to prevent freezing of the walls of the opening surrounding it. Such an installation entails other requirements for the design of external slopes that appeared as a result of moving the window unit indoors.

The finishing of such openings in a log house can be done using plastic moldings, the edges of which are closed: at the window - the initial one, and outside, at the point of contact with the facade - with F-shaped strips.

But the best option Arranging a wooden opening will involve installing a box made of a wooden L-shaped board.

However, it should be borne in mind that Such design of a slope will cost a pretty penny, because such a board should be made according to individual order and according to certain sizes. Yes, and qualitatively slaughter each other corner connections boards are not at all a simple matter and require professional skills.

However, if the installation steps are carried out correctly, the result will undoubtedly please you, since only natural wood can look 100% organic with a natural wooden facade.

In houses made of concrete, brick or gas silicate blocks, there will be slopes made from a plaster composition used for external work, puttied and painted in desired color(usually this is the color in which the entire facade is painted).

To give external window slopes a distinct personality, you can use ceramic tiles for exterior use or decorative finishing stone to decorate them.

You can often find brick or monolithic houses, the basis of the façade finishing of which is an external plaster insulation system.

The principle of this type of insulation device is that external wall First, foam or mineral wool is glued and then additionally fixed with disc-shaped dowels, which are subsequently covered with a special mesh and plastered.

If a house with an external plaster system is not insulated external slopes Before finishing them, they will become cold bridges through which heat will escape from the room.

This may also lead to uninsulated places will become conductors of high humidity, which will subsequently result in the formation of condensation, as in internal surfaces glass and on internal slopes.

How to arrange external slopes

The beginning of finishing slopes from any material you choose should begin with sealing the installation seam between the frame and the wall.

As I already said, there should be no polyurethane foam in the seam; it must be covered with PSUL tape. All other options are a violation of the technology for installing plastic windows.

But, although the owners of the installed windows are not to blame for encountering illiterate installers, nothing can be done - the situation needs to be corrected.

After the window block is fixed in the opening, it will be impossible to install the PSUL tape into the mounting seam, even theoretically, since this tape is mounted immediately before installing the window on the outer part of the plastic frame - using an adhesive base applied to one of its sides.

In addition to the PSUL tape, the mounting foam is not as high quality, but it can still be protected by applying a couple of layers of oil paint to it or sealing the seam with construction tape.

After this, you can continue the process of finishing the external slopes, for which you need to install an external window sill drain.

This seemingly simple stage, as well as the issue of protecting the polyurethane foam, is worth considering in detail.

External window sill flashing cannot be attached to the outer part of the window frame, as some would-be installers do. The ebb tide has its own regular installation location. The upper protrusion should be in the groove located at the lower end of the plastic frame.

The edges of the flashing should be trimmed and bent so that they can be pressed tightly against the side slopes.

Subsequently, these curved parts should be plastered on top or covered with piece side slopes. External flashings are made of thin sheet metal, which in good rain can act as a drum, so before installation you should inner part low tide, apply noise-absorbing tape. AND It wouldn’t be at all out of place at low tide with inside stick PSUL tape

, which, just like between the frame and the slope, will cover all the potholes and the ledge.

So, the installation seam is closed, the ebb is installed according to all the rules. Now you can safely begin finishing the top and side slopes.

Slopes on a vinyl siding façade For finishing a house whose walls are covered vinyl siding

, standard joints for connecting shaped parts around a window opening have been developed. When installing these parts, be aware that they are installed after the load-bearing frame

, but before finishing panels begin to be attached to the frame.

First of all, the initial strip is attached to the window along the entire perimeter, then the lower ebb, upper and side slopes are inserted into it in turn, which are cut together and secured with screws to the building's skin.

There are practically no difficulties when installing slopes made of vinyl moldings.

The exception, perhaps, is the need to take special care when cutting the joints of connecting shaped elements.

The process of plastering the outer part of a window opening differs from plastering the part that is located inside the room only in the composition of the materials used.

For comfortable application of plaster on internal slopes, a gypsum binder is often added to the plaster composition.

This additive makes the plaster more elastic and adheres better to the surface, which is especially important when constructing an upper slope. If you are sure that the internal slope will not be in a zone of high humidity, then cement-sand plaster

can be safely completely replaced with acrylic or plaster.

For finishing external slopes, only a cement-sand composition with the addition of the necessary additives that improve its adhesive characteristics is suitable. This plaster is not afraid of any weather conditions. To ensure that the applied composition holds better and does not crack when applying a large layer, it can be applied to metal plaster mesh

– such plaster reinforced with reinforcement is guaranteed to protect the junction of the frame and the wall for a very long time. The plastering solution is prepared according to the instructions indicated on the package.

It is very important that it is developed during the time it is in working condition. This period is also necessarily indicated in the recommendation for use.

The application of plaster depends on the professional skills of the finisher: some use a trowel, applying the mortar to the falcon and throwing it onto the slopes, others use different types of spatulas for these purposes. If you want to carry out this work for the first time and on your own, I think that you will have difficulties with both the first and second options, because the main thing in this matter is having experience. But after spending a few hours training and listening to the recommendations experienced craftsman

, it is quite possible to sketch a couple of linear meters of plaster covering the side slope.

Another day of training - and you can begin constructing a horizontal upper slope, which is a more complex task than applying plaster to the vertical surfaces of the side parts of the window opening. After plastering, allow the slope to dry completely.

(drying time must be indicated on the product packaging)., the composition of which is suitable for use for external finishing works. If you made the slope yourself, and not everything turned out the way you wanted, that is, evenly and smoothly, then you can hide small flaws made during the plastering process by applying decorative finishing plaster or putty to create textured coatings.

Before filling, the mandatory conditions, without which this process cannot be started, are complete drying of the plaster composition and priming of the entire plastered surface.

The final and easiest step is painting the finished surface. To deal with it without problems, you need, just like at the previous stage, to wait completely dry surface and prime it.

For an example of installing slopes on window openings of buildings covered with corrugated sheets, see the video:

Slopes on window openings of buildings trimmed with corrugated sheets

For residential buildings, facade finishing with profiled sheets is practically not used - this is the prerogative of household and production premises. But since we are talking about all external slopes, we will briefly consider this material for decorating window openings.

Installing metal slopes is not a difficult task.

To do this, you only need sheet metal coated in the color of the facade, two types of corners, rivets (preferably matching the color of the metal), short screws and a special tool:

• drill or, better yet, a screwdriver;
• metal scissors, preferably electric;
• a set of drills with a diameter corresponding to the diameter of the rivets.

First on window profile Along the entire perimeter, a corner is screwed to the very edge with self-tapping screws, the size of the shelves is usually 20x20mm.

Then from sheet metal a blank is cut corresponding to the width and height of the closed slope. This blank is riveted on one side to a corner mounted on the frame.

The next step is that a second corner is riveted to the outside of the workpiece, which is made to individual sizes in such a way as to cover the junction of metal sheets installed on the wall and on the slope.

How to make insulated external slopes

It is especially necessary to insulate the surface of external slopes when the entire building is insulated from the outside.

If insulation is carried out according to the principle of a ventilated facade, and the slopes are covered with the same material that is on the facade (it does not matter, porcelain stoneware, metal profiles or vinyl siding), then, as a rule, a layer of mineral wool twice as thin as the insulation layer is glued under the cladding the remaining walls of the building.

If the building is insulated with foam plastic or mineral wool, which are covered with protective finishing plaster, then the slopes must be insulated with similar materials and finished with the appropriate plaster composition.

To finish slopes without being tied to an external insulation system, you can use extruded polystyrene foam - penoplex.

This material can serve as an analogue of drywall when it is used for interior decoration of a window opening. It, like plasterboard, can be glued to brick, concrete or other material framing the plastic window from the facade. After gluing to fully guarantee its reliable fixation Each side can be additionally secured with disc-shaped dowels.

Then a fiberglass plaster mesh should be glued to the surface of the penoplex and filled with façade putty. After drying, the putty is cleaned with fine sandpaper

, primed and painted, again with façade paint in the desired color.

The need to comply with technology

The construction of internal and external slopes in accordance with all construction rules has many aspects and details. It makes no sense to consider them all, because such knowledge is needed only by a limited group of theoretical builders. You need to know the basic conditions, without which operation window products

, as well as the comfortable atmosphere in the room where they are installed, will be at risk.

The main requirements for modern filling of a window opening are a well-made connection to the wall openings, as well as correctly selected components of the window structure itself. To begin with, from all the offers you should choose the profile that is perfect for working in your conditions. climate zone

. That is, it must have the required width and such a number of internal chambers that it fully meets building standards for heat and sound insulation.

But it’s better to think for yourself and choose one of the proposed options:

• double-chamber heavy double-glazed window, the weight of which (for a large sash) will eventually affect the operation of the fittings;
• single-chamber with low-emissivity glass and gas-filled chamber with the same sound and heat insulation, but with less weight and, therefore, more reliable functioning of the fittings.

When the window unit is ready for installation, in order for it to provide a truly high-quality thermal effect in the room, you should not only know the basic principles of design and installation, but also strictly follow them.

Therefore, the responsibilities of the customer for the installation of new plastic windows should include monitoring compliance with all installation rules.

You should ensure that:

• the size of the window block's indentation from the surface of the opening walls did not exceed 10-20 mm;
• when sealing the installation seam, temperature deformations were taken into account and thermal changes window design;
• on the street side, a pre-compressed self-expanding tape must be installed;
• On the side of the room, a vapor barrier was installed in the form of a continuous contour along the entire perimeter of the window block.

Remember that work on the construction of internal and external slopes is aimed at reducing heat loss through external enclosing structures, which in this case are window units. It is through windows that 40 to 70% of the total heat loss of a building can occur.

Even if the window unit itself complies with all thermal engineering standards, heat will still freely leave the building due to air infiltration through the frame’s connection to the opening made in violation of the rules.

Problems associated with improper finishing of slopes

Due to the specifics of my work, sometimes I have to deal with situations and resolve issues related to the consequences of illiterate installation of window structures.

As a rule, such questions arise when a person independently decides to install plastic windows in his home, deciding that there is nothing complicated about it.

Or the second, often encountered situation - the customer hired the guys without recommendations, guided only by the fact that when discussing the work they “threw their fingers wide” and assured that they were doing repair work in Pugacheva’s own house.

It’s a strange thing, for some reason all the “shabashniks” try to introduce themselves as the favorite builders of popular celebrities. Like, they have a couple of weeks while the team moves from the site they built for Galkin to the construction of Kirkorov’s dacha. During this time, they can, so be it, help you out, and perform complex tasks for “two pennies.” construction works. And what’s surprising is that many people believe them.

But this is just me, not the topic, you just really see this quite often, and so I expressed that it hurts.

“Great builders” leave, leaving behind heaps of garbage and promises: if anything happens, they will immediately return and fix everything. But when everything appears Negative consequences their “professional” work, then neither the promised guarantee nor themselves can be found during the day.

And what should I do when people come (now understanding what their mistake was) and ask to eliminate the defects that have appeared?

You have to maintain your resume as a decent specialist and, after a little suggestion, which is to instruct the customer not to repeat such mistakes again, still send a team to eliminate the causes of discomfort for customers.

And there are plenty of reasons like this:

• uninsulated internal slopes. The result is freezing and condensation from frequent temperature changes;
• cracks on the surface of internal and external plastered slopes. The result is the penetration of moisture from the street, the formation of fungus and mold;
• water flowing in and blowing under the window sill due to improper installation of the external drip sill;
• the appearance of a draft in the area where the frame adjoins the internal slopes. As a rule, this occurs due to the destruction of the mounting foam due to improper installation of the slope insulation system;
• shedding of plaster or putty from the external slope due to violation of the technology for working with plaster compositions or the use of materials not suitable for external work;
• failure of the external finishing of the slopes. This occurs in cases where they are used to construct external slopes. Decoration Materials, not used for outdoor finishing (for example, PVC panels that are used for interior work).

Elimination of the above defects is, of course, possible. But, for example, in order to properly connect the window frame to the opening, it is necessary to dismantle both the internal and external slopes.

Such work takes a lot of time and costs twice as much as initially correct insulation and finishing of slopes.

Appearance

Compliance technological features when installing window units, this is a primary task, but not the only one.

At the same time, we should not forget that the installed window blocks should not stand out in color, violate the geometry of the building and spoil the appearance of the facade. External window slopes Only then are they considered a professionally made part of the window structure when they are made in compliance with technical standards

and are part of the decoration of the facade of the building. It is important to know that for those buildings that are finished decorative stone

, metal frames or vinyl moldings cannot be installed on external slopes.

• It is possible to clad the outer parts of openings with finishing stone where the following materials are used for facade finishing:
• a natural stone;
• ceramic tile;

clinker or polymer panels.

On buildings finished with vinyl siding, vinyl shaped parts that come complete with the main façade trim will look most organic. For a facade on which metallic facing coverings (profiled sheets, metal siding, as well as metal cassettes), the best choice for finishing external slopes would be a metal sheet

, painted in the main color of the building and installed in the opening using finishing metal corners.

When considering options for constructing slopes for buildings made of brick and concrete, the natural choice would be to finish the window opening with a plaster compound, followed by puttying and painting. The most difficult thing will be the choice of external arrangement of a window in a wooden frame. Attractive naturalness wooden building can easily be lost if you try to mix several styles in its exterior decoration. Therefore, the profile of plastic windows must have an appropriate wood finishing

lamination, and external slopes are best covered with a box made of natural wood.

As a result, I would like to note that when installing a window unit, you should always consider the entire range of work: installing the window, installing connections, installing external and internal slopes. Only in this case will you receive the expected pleasure from the long-term and reliable operation of the installed plastic windows.
