How to beautifully make windows on the outside. Window cladding inside and outside. Framing openings - examples of installing slopes from different materials
The strength and durability of a building depends on many factors, including the high-quality finishing of window slopes. Cladding gives a beautiful look not only to the windows, but to the entire building as a whole.
The easiest way to have a beautiful front lawn
You've certainly seen the perfect lawn in a movie, on an alley, or perhaps on your neighbor's lawn. Those who have ever tried to grow a green area on their site will no doubt say that it is a huge amount of work. The lawn requires careful planting, care, fertilization, and watering. However, only inexperienced gardeners think this way; professionals have long known about the innovative product - liquid lawn AquaGrazz.
External finishing of plastic windows
Finishing plastic windows on the outside is not only an aesthetic need, it can significantly reduce heat loss from windows and walls. Slopes, in addition to decorative, also perform a protective function - they protect windows from harmful atmospheric influences, moisture, prevent the formation of fungus or mold on the windows, and also increase the insulating properties of plastic windows. By insulating the slopes, you can completely eliminate the possibility of moisture on the surface of the window. Each of the existing window insulation technologies allows you to take advantage of the full range of modern, high-quality materials that not only have an affordable price, but also excellent performance characteristics.
If you have recently installed plastic windows, do not delay finishing them, as unlined slopes will make the openings leaky; the polyurethane foam quickly collapses under the influence of rain, wind and sunlight. After installing the windows, you should take care of high-quality finishing of the slopes on the outside. High-quality slopes protect plastic windows from the negative effects of atmospheric phenomena and possible deformations (distortion) during operation.
Decorative window covering
Decorative window cladding can be very diverse thanks to a wide selection of modern finishing materials, and the ability to install colored double-glazed windows allows you to combine the exterior decoration with almost any exterior. For window cladding, in addition to the finishing material itself, various additional elements are used.
If you wish (and have certain skills and a minimum set of working tools), you can do the work of insulation and finishing of slopes with your own hands.
Among the popular options for facing openings are:
1. Plastering slopes.
2. Cladding with sandwich panels.
3. Slopes made of plasterboard.
4. Wood finishing.
5. Metal finishing.
6. Stone finishing (natural, artificial).
7. Foam finishing.
8. Finishing with plastic panels.
Most of them can be installed with your own hands, which not only gives the openings an aesthetic appearance, but also saves your budget.
Let's look at each option in a little more detail.
Plastering window slopes
Plastering slopes is the simplest and most economical way to finish their exterior. The plastered surface combines perfectly with the design of plastic windows, and the simple technology will be within the power of a beginner doing repairs with his own hands.
Window finishing with plaster includes:
— thorough preparation of surfaces - cleaning from dust, removing excess polyurethane foam. To avoid staining the frame and window sill, they must be covered;
— installation of beacons (special metal profile);
- applying plaster mortar with a spatula (the surface between the beacons should be perfectly flat and smooth);
— leveling the surface and filling the resulting voids with solution, repeating the steps if necessary;
- applying a second layer of plaster (after the first has dried), the total thickness should be at least 1-1.5 cm;
— surface grinding;
- coating with finishing putty;
— preparing the surface for painting;
- coloring.
Finishing window openings with sandwich panels
Finishing window openings with sandwich panels is an ideal option for finishing windows from the outside. Sandwich panels are a multilayer structure consisting of several sheets of plastic and polyurethane foam (foam), which is located between them. These panels have a number of positive qualities: they are easy to install and clean. Thanks to their unique design, they protect windows from freezing and blowing, and the variety of colors will not leave anyone indifferent.
Finishing with waterproof plasterboard
Finishing with waterproof plasterboard is perhaps the fastest way to cover window slopes. The installation principle is similar to the installation of plastic panels - the sheathing is installed, and pieces of drywall are screwed to it, the cracks are filled with polyurethane foam. For additional thermal insulation, the internal space of the slopes can be filled with mineral wool or foam plastic. To ensure that the cladding is airtight, the surface of the plasterboard slopes is pre-treated with a special antibacterial impregnation, and after installation they are covered with a layer of putty that hides the joints. Then the slopes are sanded and painted. The advantage of this material is the speed of work, because only with its help can you get smooth, beautiful, perfectly even slopes in the shortest possible time.
The wooden window trim will be appreciated by fans of the natural style in decor. This environmentally friendly material looks very beautiful, especially if the façade of the house is also made of wood. The disadvantages of this option include the high price and the need for pre-treatment (to protect against negative environmental influences).
Finishing window openings with metal
Finishing window openings with metal is one of the most reliable and practical methods. When installed correctly, metal slopes guarantee long-lasting, airtight window protection. They are made of galvanized steel with a polymer colored coating that protects the material from corrosion and rust. Metal slopes are a universal option; they go well with any windows and any facades, the main thing is to choose the right color scheme. As a rule, they are made to order, according to individual measurements and attached using self-tapping screws. For greater tightness, the seams are treated with silicone sealant. If desired, the color of such slopes can be easily changed using paint.
Stone finishing of window openings
Stone finishing of window openings is superior to all of the above types of cladding in terms of aesthetics - it has a unique design and harmonizes perfectly with other external decor. For example, part of the slope can be covered with decorative plaster, and small stone tiles can be fixed to it. The technical characteristics of the stone coating are impressive: moisture resistance, frost resistance, resistance to sudden temperature changes, durability, combustion resistance. The stone surface does not absorb dirt, so this type of finish is almost ideal.
The most popular option is:
- granite;
- gravel;
- sandstone.
However, natural stone is an expensive and rather difficult to install material that is heavy, so it is not very often used for cladding slopes. Artificial stone has a more affordable price and lighter weight, but has characteristics similar to natural stone.
Finishing slopes with foam plastic
Finishing slopes with foam plastic is one of the most cost-effective ways to process and insulate slopes.
Foam finishing technology includes:
1. Surface preparation: thorough cleaning of dust, dirt, foam residues, filling holes, cracks or potholes with cement mortar (or adhesive cement). It is mandatory to apply a deep penetration primer layer.
2. Cutting blanks from a sheet of foam plastic with a thickness of at least 5 mm that are suitable in size for the slopes. Applying an adhesive-cement solution with a spatula and then applying it to the surface of the slope. The sheet must be carefully leveled (using a level), and after the adhesive solution has dried, secure it with dowels.
3. After the foam is securely fastened, a layer of starting putty is applied to it, onto which, in turn, a reinforced mesh is attached, as if pressing it into the putty layer. To protect the corners, it is necessary to install special metal corners.
4. Applying a layer of finishing putty, sanding with a grout mesh and painting (if necessary).
As you can see, there are no difficulties when decorating the windows externally, so this work can be done with your own hands, without the involvement of expensive craftsmen.
Window finishing with plastic panels
Finishing windows with plastic panels is a practical solution. Such panels are designed for a long period of use, have a beautiful appearance, and the process of their assembly is extremely simple and takes a minimum of time (finishing can take only a few hours). When choosing a material, you should focus on panels intended for outdoor use - they are more durable and do not fade under the influence of ultraviolet radiation.
There are several types of plastic panels that are used for window finishing:
— sheet (the most popular type, characterized by increased thermal insulation properties, resistance to temperature changes, various acids and alkaline substances, and high humidity).
— cellular (used very rarely due to the increased fragility of the finishing coating and poor color stability to ultraviolet radiation).
Knowing the basic rules for selecting materials and the technology for finishing slopes and covering plastic windows, you can avoid many mistakes, especially if you are doing home renovations yourself. For example, installation and finishing of plastic windows is best done in dry weather at above-zero temperatures, since frost and high humidity can have a detrimental effect on structural elements.
Attention to details and their careful elaboration gives the interior a finished look. External slopes on windows are a mandatory element, so you don’t need to be content with just the installation and interior finishing of double-glazed windows.
Sheathing that imitates natural materials with a higher quality than themselves is, if not a dream, then at least an object of desire for most homeowners.
If such cladding is relatively inexpensive and can be installed in a short time, then its preference is undeniable. These are the characteristics that siding has.
Houses covered with siding have clear, even outlines and look neat and stylish. Such a finish, for all its external ideality, is quite simple and accessible to everyone; you just need to familiarize yourself with the general structure and several installation rules.
The installation itself is simple and intuitive for anyone; some questions arise when decorating elements of the house, in particular window openings.
- Platbands.
- J-bars.
- Finish profile.
- Corner strips (complex).
- Simple corner.
- Sections of main panels.
The listed elements are not needed all at the same time; this list includes elements that may be needed in one case or another.
A more specific list can only be compiled by having in front of your eyes a specific opening with its own parameters, the main ones being the presence and depth of slopes.
NOTE!
Many manufacturers produce their own elements for decorating window openings, which are used only for a certain type of siding. When purchasing casing, you should find out what components are needed for it and whether there are any specific parts.
Preparing slopes for cladding
Before starting work, you should prepare the opening. To do this, you need to remove all the design details - old slopes, casing, external window sill strip, etc.
The opening must be freed from all additional elements - brackets for lights, fasteners or other elements that interfere with the installation of the casing. The surface of the slopes should be cleaned of old paint, various layers, and all crumbling or peeling areas should be cleared and removed.
The presence of a large number of imperfections on the surface of the slopes may require the application of a leveling layer of plaster; in simpler cases, putty can be used.
Thorough surface preparation is mandatory and should be handled with the utmost responsibility., since after installing the siding there will be no access to the slopes.
Installation of sheathing
Along slopes it is installed simultaneously with the main one. All procedures are carried out - insulation, installation of sheathing strips, etc.. The same material is used as for the main sheathing - wooden blocks or metal guides for gypsum boards.
At the same time, it should be taken into account that the installation of sheathing on slopes of great depth should be carried out taking into account the thickness of the insulation, the ventilation gap and other technological dimensions.
The fact is that the dimensions of the window block have a certain size and do not always allow you to completely install all the necessary elements - the casing may turn out to be too far from the plane of the slope and partially block the light opening of the frame.
In such cases, it is necessary to reduce the thickness of the insulation (or completely abandon it in this place), reduce the ventilation gap in order to achieve an acceptable position of the design elements of the window opening.
Window finishing with siding without slopes
To decorate windows installed in the same plane with the wall (without slopes), platbands will be required.
To install them you will need:
- A starting profile is installed on the frame around the perimeter of the window. If there are many windows and they are large, then the consumption of the starting strip may be large. To save money, you can get by with pieces about 8 cm long; you don’t have to install whole strips. The profile is attached approximately 5 mm from the edge of the box with the locking part towards the window.
- Platbands are adjusted in length, their outer planes are cut at an angle of 45°, for which it is convenient to use a miter box or electric saw on a special stand, which makes it possible to make precise cuts at a given angle.
- The internal elements of the platbands are cut according to a certain pattern. The upper casing along the end part is cut and bent down so that rainwater falling inside can flow down these bent parts into the side elements. The side platbands are cut from the inside so that the fastening and profile elements do not intersect with the upper platband, and the lower platband is cut in the same way. When trimming internal parts, remember to leave temperature gaps of about 3 mm.
- Installation takes place according to the usual scheme - the platband is snapped into place with the locking part in the starting profile, and secured to the sheathing along the nail strip with self-tapping screws. First, the lower casing is installed, then the side ones, after which the installation is completed by installing the upper casing.
- Installation of platbands is carried out simultaneously with the installation of corner and H-profiles before installation of the main siding panels.
Window finishing with siding with slopes
The method of finishing slopes depends on their depth. To design slopes up to 20 cm deep, a near-window strip is used.
The installation method is similar to the installation of platbands, but there are also slight differences:
- Window trims are cut to length. The top and bottom parts are installed first, but the trimming of the inside is different.
- The upper part of the near-window strip is cut from the inside so that the side slopes do not intersect with the internal end elements of the profile. From the outside, it seems to rest on the side slats. Trimming at 45° is not required in this case..
- The lower part rests against the side slats from the outside. At the same time, parts of the slope sides are not cut off from the inside, but are folded upward under the side planks. Actually, you can do the same with the upper bars.
- Installation of near-window profiles is carried out by attaching the slopes to the finishing strip and fixing the other edge to the wall sheathing with self-tapping screws.
- The side strips are installed after installing the horizontal parts.
To design slopes more than 20 cm deep, a set of sections of siding panels is used. In this case, the installation of each slope can be considered as cladding of narrow partitions or soffits.
- A finishing strip is installed around the perimeter of the window frame.
- An external corner is installed along the outer perimeter of the sheathing.
- Siding sections are installed between the corner and finishing profiles. When cutting, take into account the size of the temperature gap.
- The corners of the slopes are formed using simple corners (simply covered over), or double j-bars are used, as is sometimes done for internal corners. They are installed at an angle to each other end to end, one bar fixes the vertical slope, the second - the adjacent horizontal one.
- With wide slopes, there must be a low tide along the lower part. It is installed before attaching the vertical sides; its side parts are folded up and placed under the vertical elements of the siding. This allows for high-quality water drainage and prevents runoff from penetrating under the casing.. The depth of the ebb is 4 cm greater than the slope (3 cm protrudes forward for water drainage, and 1 cm is bent for installation to the window frame).
Conclusion
Finishing window openings is one of the most difficult operations when covering a house with siding. All questions that arise during the execution of work most often relate to the correct cutting of framing elements and the order of installation of parts.
Before starting work, it is recommended that you carefully read the manufacturer’s instructions that come with the siding. It describes in detail the installation process of all elements and, in particular, specific parts and components (if any). Once all the issues have been clarified, no special problems will arise and the window openings will be finished properly.

Today, window replacement has become very common. Old frames are still being actively replaced with modern analogues made of plastic, metal and wood. The installation process itself occurs quite quickly, which cannot be said about finishing the windows from the outside, since this procedure has a number of technological requirements, and from an aesthetic point of view, the owner should be satisfied. In the article we will analyze various ways to create beautiful and reliable slopes and frames, focusing on materials and methods of their installation.
So, why is it worth paying close attention to the correct finishing of windows on the outside. The first thing that comes to mind is the neat appearance of the building. Without quality framing, you can’t expect your home to look neat. Slopes and platbands are actively used in shaping the style of a building, its design, but not only. In many ways, they directly affect the comfort of people staying inside the building:
1. The technology for installing window frames requires leaving a technological gap, that is, they are never placed close to the walls. The resulting gaps are necessary to compensate for movements of the structure as a result of shrinkage and even seismic activity, as well as the window system itself under temperature influences. If this technology requirement is violated, any changes would lead to deformation of the frames, which would cause the windows to stop opening, and possibly the glass would be squeezed out.
2. The technological gaps left are direct routes for heat exchange between the room and the street, so they must be insulated. Previously, tow, wool, and felt were used for these purposes; now it is mainly polyurethane foam or mineral wool.
3. All of these types of materials quickly deteriorate if they come into contact with the atmosphere, moisture, wind, ultraviolet rays, which is why they need reliable protection.
As protection, a coating made of materials that are immune to the above factors is used. At the same time, they must be sufficiently attractive and correlate with the systems with which the façade of the building is finished. In other words, the material of the slopes must be visually and technically combined with the material of the walls.
Plaster type slopes
Windows can relate differently to the plane of the walls - either they are recessed inward and there are perpendicular slopes, or they are aligned in one plane. In the second case, to protect the insulation, only an overhead casing is required, however, such a solution can be implemented mainly only during the construction of a new house, or old windows were installed in the same way. Making a platband is much easier than making a slope.
So, the first on our list will be plaster slopes. They can rightfully bear the title of a classic version.
For such slopes, a sand-cement mixture is used, from which the outline of the window opening is completely formed. Today, this method is not as popular as it used to be, but many still consider it the most reliable and durable solution.
They are used if the walls of the facade of the building are either completely plastered, or an architectural element is formed from the mortar, which will outwardly blend harmoniously with the material of the walls.
The advantages of such slopes are the availability of materials and a fairly simple manufacturing technology; this finish is resistant to atmospheric influences and looks simple but neat.
An experienced craftsman will make a high-quality slope within a few hours, if we are talking about a simple rectangular shape. Complex compositions with non-standard geometry can be very time consuming. It’s almost impossible to do something like this yourself without experience and templates.
Cement plaster requires a certain amount of drying time, which will not allow you to immediately decorate the structure. It is also worth considering that such work is dirty, so you should be careful.
Interesting to know! For work, you can use any plaster mixtures, including decorative ones, for example, bark beetle. It all depends on the design approach.

How to make a plaster slope
Now let's figure out what is required for such work and in what sequence it is performed. We are preparing the following tool:
- Container for mixing plaster mixture.
- Electric tools for mixing - mixer, electric drill, hammer drill.
- A set of spatulas for applying the mixture, a corner trowel, and a trowel for applying the plaster.
- Tools for determining the evenness of a slope - a plumb line, a bubble building level, a laser axle builder.
- Wide brush with soft bristles.
- Plaster float.
We purchase the following materials:
- Ready-made dry plaster mixture or cement with sand, if you decide to save a little. The slopes do not require a lot of material, so it is better to buy it ready-made, since the factory composition contains plasticizers in the required proportions, which adds elasticity to the solution - in general, makes working with it more comfortable.
- Putty mixture. Compositions for external work are used, including decorative plaster, applied only as a finishing layer.
- Deep penetration primer for exterior use, which will reduce water absorption of the base and strengthen it.
- Fiberglass mesh for slope reinforcement. This material is inexpensive, but significantly strengthens the concrete layers, so do not neglect it.
When choosing a ready-made solution, we advise you to pay attention to the additional properties of the material. Thanks to the use of certain additives, the compositions can differ favorably from the classic sand-cement mixture. For example, thermal insulation plaster will additionally insulate your window. It contains foam glass granules, perlite, and vermiculite, which imparts similar properties. In addition, the material is moisture resistant. Fiber fiber is often used for additional reinforcement.
Now let's take a step-by-step look at how slopes are plastered. In fact, the technology includes only two stages - placing beacons and working with the mixture. If everything is clear with the second point, then the first has many options for execution. Today we will look at a modern method that will help to do everything efficiently even for a beginner who has not encountered anything like this before.
Table 1. Plastering slopes.
| Photos, steps | Description |
|---|---|
| First, the base must be cleaned of dirt and dust. This is done using a regular brush. Next, a layer of primer is applied, which needs to dry well. The drying time is indicated on the jar with the composition. This step is mandatory, since due to low adhesion the plaster may fall off over time. |
| Installing this element is rightfully considered the most difficult, but not the option that we will offer you. Here is a special beacon profile for slopes with reinforced mesh and an adhesive base. It is inexpensive, but saves a lot of your time and nerves. Installation occurs in the following order: 1. An indentation is made from the edge of the frame exactly the width of the profile. You can navigate directly along the edge, but we advise you to put additional level marks so that you don’t have to tear off the glued profile if it misfires, and the window itself may not be positioned exactly. 2. Remove the protective tape from the reverse side to release the adhesive base. 3. The profile is glued along the marks. Attention! If your slope is very wide, extend the fiberglass mesh using a separate roll. |
| The second beacon can also be made in different ways. Let's take a specific example in which the craftsman uses a metal rule and even pieces of plywood sheets. He states the rule as follows: 1. Two holes are drilled in the wall at a certain height into which plastic dowels are inserted. 2. Then homemade clamps are installed, as in the photo, consisting of a platform and a short support on one side. There is a slot in the platform for a self-tapping screw so that the height can be adjusted. 3. A rule is set under the free end of the clamp, it is clearly leveled, after which the screws are tightened for reliable fixation. |
| It is much easier to place beacons on the side walls. The photo shows another option. Plywood was used, in which cuts were made to allow for quick adjustment of the position of the element. It is also attached to dowels. All external beacons are set strictly at an angle of 90 degrees with respect to the window frame along the internal beacon. |
| Next, the plaster mixture is mixed. It must be thrown inside the slope so that it sticks securely to the base. Attention! In no case is it allowed to spread the solution, only throw it on. If desired, the plaster can be further strengthened. To do this, screw dowels are screwed into the base and do not reach the end. The protruding cap will significantly strengthen the structure of the slope. Advice! To avoid the solution sticking to the plywood, the latter can be coated with waste oil or covered with a plastic bag. This measure will further increase the service life of the device. |

Frame-type slopes
So, if plaster is a continuous covering of a slope, then there is also a frame type, when there is empty space inside that can be additionally insulated. The choice of material for such solutions directly depends on the type of building cladding. Slopes can be made of plastic, wooden lining, vinyl or metal siding, window profile, metal cassette element. The installation of these materials is almost identical, so we did not separate them.
View the following photographs showing similar slopes.
Each of the listed materials has its own set of characteristics, but none of them provides the window system with additional thermal protection, like special compositions of plaster mixtures. However, there are methods for insulating such slopes: the internal space is filled with polyurethane foam or mineral wool.
Installation proceeds according to the following scheme:
- A frame is exposed, which can be external and internal, or only external. In the first case, a belt of slats or metal profiles is attached near the window frame and the same along the outer perimeter of the slope. In the second - only the outer element - the inner one is replaced with a starting profile, which is attached directly to the frame. The last solution is suitable for plastic and thin lining.
- All frame elements are set clearly in level, since they completely determine the geometry of the future slope.
- They are attached differently, depending on the material. Most often, anchors and metal hangers are used as fasteners.
- The finishing material is installed according to the fastening scheme of the specific material. For example, wooden lining can be held in place by nails and self-tapping screws directly or through metal clamps, and siding is held in place by self-tapping screws and a special fastening profile.
- The outer corner of the slope is covered with a decorative element. Usually these are overhead corners, examples of which you could see in the photographs shown above.
It is much easier to make a frame slope than a plaster slope, and in 90% of cases it does not require additional processing. The product begins its service life immediately after installation. Everything would be great, but not every material will last long. Painted elements fade over time in the sun, wood can rot and change color. You can repeat the coloring, but it will not look like the factory one, and the slopes will definitely lose their attractiveness. But plaster surfaces can be renewed an unlimited number of times.

Decorative elements for window framing
Agree, you won’t surprise anyone today with ordinary slopes. How then can you improve the appearance of your home? For these purposes, various elements and techniques are used that can be combined with the previously described types of slopes.
1. You can frame the windows polyurethane linings. They are installed with glue, so you need to ensure a level base with good adhesion. They are also suitable for brick walls.
2. Smooth plastered slopes will serve as an excellent basis for finishing with various decorative materials. The photo shows an option for decorating the window outside decorative artificial stone. Clinker and porcelain tiles will also look beautiful.
3. Extruded expanded polystyrene is also used for similar purposes. Such systems consist of corner elements and a straight profile. Everything is put on glue. You can choose any color from those available, or paint the material yourself.
4. In cases of façade renovation using decorative brickwork, the windows can be lined separately with shaped products to give them an unusual, beautiful look.
5. You can use the services of professional craftsmen who can create masterpieces like this for an expensive price. stucco moldings. Such windows look very beautiful, luxurious and rich.
6. Sandrik- This is a small architectural element above the window that can be made of concrete, plaster, polyurethane and foam. The difficulty of installing the part depends on the material.
7. Pyramid or wedge-shaped decorative element, made from the same materials. Installed at the top of a vault or arch, above the window.
8. You can install it under the window false baluster.
It is worth noting that determining the necessary decorative elements is quite a complex matter. If you overdo it, then instead of beauty you will end up with wild pretentiousness and bad taste, so do not be afraid to consult professionals. Of course, they charge money for their services, but remember that you are creating the appearance of the house and will be looking at it for many years, and only positive emotions should arise from contemplation for you and the audience.
Today, in residential buildings, almost everywhere, old, outdated ones are being replaced, replacing them with modern plastic ones.
This pleasure is not cheap, and some people, when replacing windows in a house, refuse to install external slopes in order to save money. But finishing the window slopes from the outside is an important component of the repair, and today we’ll talk about it.
They have excellent heat and sound insulation; they do not need to be insulated or painted. However, in order for a plastic window to serve for a long time, all installation operations must be carried out in strict accordance with technical requirements.
When installing a window into an opening, the gap between the frame and the wall is filled with mounting foam, which is resistant to direct sunlight and moisture. Under the influence of these factors, the foam can lose its thermal insulation properties and collapse. That is why it is unacceptable to leave the installation seam open for a long time.
Do-it-yourself finishing of external window slopes
It is best to immediately repair problem areas after installing the window. There are several ways to do this. The most common decorations for exterior window slopes are:
- plastering;
- use of sandwich panels.
1. Plastering is a cheaper method and, moreover, does not require special skill from the performer. It is quite possible to do it yourself.
The main thing is to do everything carefully, without spoiling or staining the profile. True, this operation will have to be performed more than once. After all, it is not very securely attached to the plastic profile and has different expansion coefficients.
Under the influence of external factors, it will certainly crack and will need to be restored.
You can plaster slopes using a plaster mixture. The walls are pre-cleaned and then a rough layer of cement or gypsum-based mixture is applied. After the rough layer has dried, a finishing layer is applied, which can then be painted.
2. Due to the fragility of the plastered layer, for modern plastic windows it is more acceptable to finish window slopes with sandwich panels.
The window looks aesthetically complete and harmonious. The sandwich panel consists of two plastic sheets, with a layer of polyurethane foam between them.
When using this method, the thermal insulation properties of the window are significantly increased, the material does not collapse and does not change its color when exposed to external factors, it is easy to clean, and is very durable. The disadvantage is the rather high cost and complexity of installation.
Sometimes cellular plastic is used for exterior finishing of window slopes. However, this option does not justify itself, since this material is very fragile, short-lived and fades in the sun.
3. In addition to the above methods for finishing external slopes, there is another method that involves using sealing polyurethane tape.
It perfectly protects the installation seam from environmental influences and removes moisture. This method has proven itself well in Western European countries, but in Russia it is still used very rarely.

P.S. Conclusion, pay attention to the qualifications of the craftsmen who will finish the external windows with slopes. I think it’s worth paying more, but you’ll get decent quality and save your nerves.
Or you can try to do this type of work yourself. Good luck!
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 the window system as a whole functions correctly: the glass does not fog up or freeze, and condensation does not accumulate on the slopes.
The installation seam on the outside must also be reliably protected from the effects of 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 decoration, which will give the window a neat, finished look.
For the interior decoration of a window opening in a 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 finishing of internal slopes with decorative artificial stone looks impressive. 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 Decorative plaster may contain fillers of various fractions and origins - these can be natural wood fibers or stone chips or artificial granules of various sizes. Decorative plaster is used as a finishing layer, creating an unusual textured surface or an intricate pattern, 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 a metal frame. 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;

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 the necessary parts must be cut out of it carefully, without any effort.
To get smooth edges at the cut points, it is necessary to make an incision along the drawn line on a sheet of drywall, applying a ruler, using a sharp construction knife. 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.

Finishing slopes with plastic panels
Finishing of window slopes inside can be done using plastic ceiling panels or multi-layer 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 a wooden block along the perimeter of the window opening near the frame using self-tapping screws;
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 the side elements first;
Side panels installed first - then insert the top panel, bend it, foam it a little and fix it in the 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 a 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 of the window frame.
Platbands
Platbands or casing for internal slopes for PVC windows can be made of different materials, but its functional purpose is the same - 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 and most inexpensive type of cash withdrawal. | |
| 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 individual 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 take on any color or imitate various types of 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. The most intricate and complex shapes can be cut from polystyrene foam. 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 manually or mechanized. 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.
Wooden platbands require careful care, 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 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.
