A lot of products have appeared on the domestic building materials market modern products, which includes roofing polycarbonate. Light-transmitting roofs built using it make it possible to create a stable connection between the external space and interior design homeownership, which is a new direction in architecture.

Requirements for polycarbonate roofing

Since polycarbonate roofs have recently become popular among property owners, it doesn’t hurt to know that such structures have a number of requirements:

A roof constructed using polycarbonate must provide an illumination value that is not less than the standard values.
It is necessary that light-transmitting slopes sufficiently protect the room from bright sunlight.
The roof structure in terms of strength, hydro- and thermal insulation, as well as in terms of protection against penetrating noise must meet building regulations and provisions.
For polycarbonate roofing it is necessary to ensure sufficient ventilation capacity and the ability to remove smoke in the event of fire.
Snow layers from a transparent roof should be easily removed.

Advantages of a polycarbonate roof

Roofs, the creation of which uses polycarbonate roofing material, can have different structural solutions - single or gable, arched and others. Thanks to this, designers have the opportunity to not limit their own imagination when designing roofs, because this material has good ductility and the same strength characteristics.

Translucent designs fit perfectly into different construction projects. The construction of polycarbonate roofs is especially recommended when arranging a greenhouse or garden planted with living plants. Such translucent roofs are an excellent solution if it is necessary to build a wide variety of outbuildings, including garages, bathhouses, gazebos, sheds, greenhouses, indoor swimming pools, etc.

The presence of a light-transmitting surface on the roof can significantly reduce energy consumption, since you can do without using electric lighting devices for most of the day. Since the room is well heated by the sun’s rays, the owners also manage to save on heat supply.

To the benefits polycarbonate roofs relate:

ability to transmit about 90% of light;
defence from infrared radiation;
high load-bearing capacity;
simple installation, simple processing;
low weight - the material is 15 times lighter than glass with a similar degree of strength;
high impact resistance;
resistance to temperature changes - such roofs can be used in the range from +120 to -50 degrees
sufficient service life - carbonate roofing is capable of maintaining its original qualities for 10-12 years;
fire safety - the material does not support combustion, and during the heating process does not emit toxic chemical compounds.

Honeycomb material

Roofing cellular polycarbonate is an ideal material for construction winter garden, greenhouses or greenhouses. This roof covering is capable of providing maximum room penetration large quantity Sveta.

Cellular polycarbonate is a panel made from leaf type of this material, which are connected by longitudinal stiffeners. These products can have a different number of layers, and accordingly differ in thickness.

Roofing from cellular polycarbonate often equipped in cases where thermal insulation performance is not significant. For example, this could be the construction of canopies in the courtyard, the installation of a canopy and other objects.

Roof coverings from of this material created indoors daylight, facilitating a comfortable stay in them, since they have excellent light transmitting qualities and the fact that they can diffuse light well.

Monolithic material

The material looks similar to silicate glass, it is smooth and transparent. Its load-bearing capacity and impact resistance are many times greater than those of glass. Roofing from monolithic polycarbonate used in the construction of pitched and flat roofs due to its insufficient flexibility.

Installation of structures made of cellular polycarbonate

Creating a translucent roof is simple and therefore many home craftsmen try to build them on own plots on one's own.

When performing installation, you must adhere to certain rules:

Cellular polycarbonate slabs are laid so that the side with protection from ultraviolet radiation was located outside - the marked film will help identify it.
The material is installed parallel to the direction of the roof slopes.
The slabs are connected using a profile in the shape of the letter “H”.
For fastening, studs and threaded screws, self-tapping screws are used, installed complete with a gasket and washer.
Holes for fastening fittings in order to ensure thermal expansion, it is necessary to make them oval or slightly increase their diameter in accordance with the diameter of the screw or screw. Polycarbonate should be laid using rubber gaskets 3 millimeters thick.
During the installation of the roof, installers should not walk on the slabs, but move with the help of pedestal boards.
The protective film is removed from the material immediately after completion of the work, since this will be more difficult to do later.
For sealing, use neutral sealants that do not contain compounds harmful to polycarbonate.

Choosing roofing polycarbonate

The thickness of polycarbonate for roofing ranges from 4 to 35 millimeters, and there are also different sizes of polycarbonate sheet. The weight of the sheet depends on this parameter, and it can range from 2 to 2.5 kilograms. There are 7 standard sizes of polycarbonate according to thickness. Each variety has its own purpose - the material must be used in accordance with their technical characteristics.

Knowing how to choose polycarbonate for a roof helps ensure that there is sufficient natural (daylight) light entering the room. This is done in each case individually, taking into account the characteristics of the structures being built.

The use of polycarbonate in the construction industry is only recognition of the exceptional advantages of the material. The canvas is produced by melting plastic granules and then passing the mass through certain forms - dies. This produces polycarbonate for the roof, which has a cellular structure and is equipped with longitudinal stiffening ribs. Today, the universal qualities of the material are in demand in the most various designs: from awnings to roofing of private houses.

Roofs made of corrugated polycarbonate are suitable for buildings of private and public importance, decorative buildings and economic facilities. Taking into account all the features of the material, you can get a durable, reliable and very aesthetic design that meets all the needs of the modern user. In addition, hangars, verandas, and greenhouses have long been successfully built from profiled polycarbonate - lightweight objects that require intense but diffuse lighting without losing stability and strength.

Corrugated polycarbonate is a polymer sheet material that differs in types. Each type has its own specific properties and performance characteristics. Roofing material is valued for its excellent practical qualities and affordable price.

Types and advantages of polycarbonate

Monolithic. It is a solid polymer sheet without internal voids. This corrugated polycarbonate for the roof has significant advantages and is not inferior in quality to durable glass. High price the material does not scare off buyers who want to make a durable transparent roof. Features of sheets in large sizes, flexibility of shape and variability color solutions– qualities that allow you to create a unique aesthetic design without much hassle.
Cellular or structured. This is an affordable material that has qualities similar to those of light-transmitting plastic. Suitable for roofs in light open buildings and other roofs, polycarbonate retains hot rays well; it is also important to use the material as partitions and advertising signs.
Profiled. This is a material with a wavy or trapezoidal profile, actively used in the process of arranging facades, roofing coverings, and canopies. Sheet material It is distinguished by its practicality and ease of installation, which provides a wide range of applications.

The advantages of the material are numerous:

high thermal insulation rates;
light weight, which ensures ease of installation;
plasticity, flexibility - qualities that are indispensable when independent work for installation of roofing structures various shapes, type, type;
non-susceptibility to chemical compounds;
long period of operation (up to 20-25 years);
low flammability;
the ability to maintain all quality indicators at temperatures ranging from -40 to +120 C;
increased sound and heat insulation due to small-sized air chambers that make up the structure of the material;
high light transmittance;
ease of processing and gluing: it is easy to make holes in the sheets and when using special compounds, the sheet is easily and firmly connected to other materials;
A wide selection of color and format solutions makes it easy to create individual compositions.

The disadvantages of the material include:

insufficient resistance to mechanical stress;
increased risk of abrasive wear;
accumulation of static electricity;
melting under high temperatures.

Important! When choosing a type of polycarbonate with increased impact resistance, you should give preference to the monolithic type. The anti-vandal qualities of the latter are extremely high, which is demonstrated by the use of sheets in public places, where the risk of intentional damage to structures increases several times.

Material parameters for the roof or canopy

Technical parameters and characteristics of the material depend on many factors; if you are planning polycarbonate roofs of a certain type, you should select optimal thickness. In accordance with SNiP 21-01-7 standards; II -3-79, attention is drawn to:

purpose of the hanging structure;
level of loads on the structure.

In accordance with these parameters, the thickness of the profiled polycarbonate is selected:

panels 4 mm thick are used for small-format objects with a large radius of curvature, for example: greenhouses, canopies, canopies;
products of 6-8 mm thickness are indicated for the construction of roofs experiencing severe wind and snow loads: hanging structures for cars, swimming pools;
panel thicknesses of 10 mm or more are used in any buildings where significant mechanical and atmospheric exposure is implied.

Important! The snow load is calculated according to SNiP 2.01.07-85 standards, which indicate the selection parameters for each region. If you choose cellular polycarbonate for the roof, what matters is the internal structure of the sheet of panels from 16 mm, having three to five layers of cells of different shapes

High-quality polycarbonate for roofing is made on the basis of primary granulate, while the manufacturer adds secondary raw materials. Percentage the last component is sometimes 65-70% and determines the cost, performance characteristics material. To determine a quality sheet visually, you should carefully inspect the sheets:

A good sheet of profiled wave material has absolutely smooth surface no bubbles or foreign inclusions.
Weight matters: for a sheet of 0.4 cm, the recommended weight is 0.8 kg; for 10 mm products – 1.7 kg.
The “light” marking indicates a reduction in sheet weight by at least 15%; it is not recommended to use it when working with such material. standard methods determination of loads.

Advice! Not all manufacturers label the product; it can only be distinguished by a reduced price

If there is no protective film on the sheets, the product not only already has a reduced quality, but will also quickly become unusable under the influence of UV rays, such sheets will not last even a year.
The thickness of the protective film with an indicator of 35 microns - sheets will withstand 5 years of operation, 60 microns - 10 years.

Advice! The buyer can determine the thickness of the protective coating only if there is a certificate attached to the product. If it is not available, the product was manufactured in the nearest alley and does not deserve any trust.

When determining which polycarbonate to choose for the roof of a greenhouse or other object, you should decide on the category:

Premium – lasts from 20 years;
Elite – 10-12 years;
Optimum – 9-11 years;
Economy – 5-8 years.

At the same time, the sizes of the sheets can be different, standard gradations are: 2.1 * 6 meters or 2.1 * -12 meters.

Without going into details technological process installation of roofs made of profiled polycarbonate of any type, we note a few useful tips:

Storing sheets involves a cool, dry room.
Before installation, the cells are closed with tape or sealant to prevent the accumulation of dust and moisture.
If condensation is detected inside the cells, the moisture is removed by blowing with compressed air.
Delete protective covering should not be removed from the sheets before laying.
A roof made of polycarbonate does not tolerate a coating made of polyester or metallized film, since condensation forms under them - the sheets and film will lose their performance qualities.
While the roofing is being installed, you cannot step on the sheets: the risk of cracks increases. To avoid damaging the coating, ladders or lathing are made.
The roof arrangement must take into account a slope angle of at least 5%; a flat polycarbonate roof is not allowed.
When installing sheets into frames, the coefficient of linear expansion, determined by the thickness of the elements, is taken into account.

Advice! Durable wave polycarbonate allows you to form roofs of any design: from standard to the most unusual. Formation of bends is possible using cold, vacuum or thermal bending methods. But to ensure that the sheet wave does not deteriorate during the transportation of sheets, careful loading and transportation is necessary - mechanical impact threatens the appearance of defects

When looking at how to choose a roofing material, determining the thickness and size of the sheets, you should take into account the factors of snow and wind loads and the possibility of removing snow and ice.

The use of translucent, durable and flexible polycarbonate has opened up new possibilities in the construction of roofs. This available material, produced in the form of panels standard size, allows you to create light, openwork, weightless structures that are optimally suited for the construction of gazebos, canopies, terraces, greenhouses or elements of urban infrastructure. The combination of low price, long service life and enormous decorative potential makes this coating a strong competitor to other roofing materials. In this article we will tell you how to make a polycarbonate roof with your own hands.

Polycarbonate is called special kind thermoplastic plastic based carbonic acid and bisphenol, which is used to build roofs and create other translucent structures. A polycarbonate roof has high impact resistance, light transmission up to 92%, weather resistance and an attractive appearance. They produce 2 types of this material:

Note! Polycarbonate roofs are constantly in direct contact with ultraviolet rays, which have a Negative influence on this material, leading to premature wear of the coating. To make the structure last longer experienced craftsmen They use plastic with a special coating that blocks ultraviolet rays.

Features of the material

Over the years of use, transparent plastic has gradually replaced fragile glass and quickly cloudy plexiglass, thanks to its excellent technical and operational characteristics. It is used to create roofs, canopies, terraces, greenhouses, greenhouses and other structures into which light must penetrate. Professional roofers note the following advantages of this material:

The polycarbonate roof has a high bearing capacity, impact resistance with very light weight. Transparent plastic panels weigh less than any other roofing material, therefore they do not require the construction of a massive frame, as well as the pouring of a deep foundation.
Plastic, especially cellular plastic, bends well, which makes it possible to easily create complex domed, arched, and shaped structures without using special tools.
This material is easy to process and can be cut without difficulty. special knife or circular saw, sticks together.
The material has high insulating properties, it protects against water penetration, effectively retains heat, and also blocks sounds.
The material has a long service life, wear resistance, and does not require special care.

Please note! When working with polycarbonate plastic, you need to consider main drawback of this material - thermal expansion. When exposed high temperature A polycarbonate roof expands, so when installing the structure, the fasteners are not tightened completely, leaving gaps.

Design principle

A polycarbonate roof consists of 2 main components: support frame, which is made from wooden blocks or metal profile, and directly roofing material. Polycarbonate is laid on a sheathing located perpendicular to rafter legs. They are distinguished by shape the following types designs made from this material:

Flat. Flat roof made of polycarbonate plastic is a structure consisting of one plane, with a slope that does not exceed 1-2 degrees. Such a roof turns out to have significant snow load, therefore it is made only from monolithic polycarbonate with a thickness of at least 8-10 mm.
Pitched. Roofs are made from polycarbonate, consisting of 1 or more slopes with a slope of up to 30-40 degrees, including tent structures. The ease of processing and light weight of the material greatly facilitates the creation of a rafter frame.
Arched. Polycarbonate plastic honeycomb type is an ideal material for creating arched roofing structures. The flexibility of this coating allows you to easily make roofs with any bend on a metal frame with your own hands.
Dome. Dome structures are made from cellular polycarbonate, taking advantage of the high flexibility of this material. However, for DIY roofing in the form of a dome is complex and requires careful calculation and adjustment.

Professional craftsmen recommend using steel or aluminum frames, since the service life of these materials is approximately the same. If, in order to save money, polycarbonate is fixed to wooden base, the bars should be carefully treated with an antiseptic composition to prevent rotting and deformation of the load-bearing elements.

Self-installation technology

DIY polycarbonate roof - practical solution For garden gazebo, canopy, carport or pool. For construction it is better to use finished project with calculation of the distance between the frame elements, the angle of inclination of the slopes or the shape of the arch. This measure allows you to avoid errors during cutting and installation. Assembly of the polycarbonate roof is carried out in the following order:

Note! If the width of the sheet of material exceeds 1 m, point fastening technology is used, and if it is polycarbonate, a special plastic profile is already used.

Video instruction

A protective canopy over a porch or a polycarbonate canopy is today de facto recognized as the most effective solution or even a home building standard. Durable and at the same time beautiful polycarbonate plastic allows you to better protect the space under the roof from snow and rain and at the same time make the canopy more elegant and attractive in comparison with slate or corrugated sheeting.

All that remains is to decide which polycarbonate to choose for the canopy, cast or multilayer cellular.

Types of roofing polycarbonate

Like any roofing material, polycarbonate plastics have their disadvantages associated with changes in the characteristics of polycarbonate due to prolonged exposure to the sun, under conditions of cyclic heating and cooling. Of course, it is preferable to find out which polycarbonate is best for a canopy before construction protective structure than to completely trust the sellers’ advertising and discover that the roofing material has failed in the second year of service.

Today, three types of polycarbonate are used for canopies:

For your information! The main quality of polycarbonate is its high strength, which is maintained throughout the entire life of the material only if the polymer contains compensating additives that slow down the degradation and aging of plastic under sunlight.

Therefore, if the list of basic requirements for a polycarbonate canopy includes the strength of the roofing, it is better to purchase a “branded” one. quality material with certificates and guarantee. It is better not to use polymer made from recycled materials for awnings and canopies; in the second year of service under the sun, it turns into fragile, glass-like, breaking plastic.

Properties of polycarbonate plastic, what to pay attention to first

Only manufacturers know all the secrets of the material; ordinary ordinary consumers have to decide which polycarbonate is better for a canopy, based on the reviews and experience of those who have used plastic in practice to equip canopies, gazebos and hanging structures.

The main characteristics of the material are given in the table, which will help to better understand the properties and predict the behavior of polycarbonate.

First of all, several interesting features catch your eye:

The above arguments do not at all mean that cast polymer is better than cellular polymer. In every specific case it is necessary to take into account the design features of the canopy and its main purpose. For example, the weight of a monolithic sheet is about 7.2 kg per square, while 1 m 2 of a cellular polycarbonate panel weighs only 1.3 kg. For easy wooden arch, with roof dimensions of 1.5x1.5 m it is better to use cellular roof covering weighing 3 kg than a monolithic panel weighing 16 kg.

Features of selecting roofing polycarbonate for a canopy

At first glance, choose which polycarbonate option would be better suited for a canopy, is not particularly difficult, but this is not entirely true. Right choice This is quite difficult to do, since it is necessary to simultaneously take into account three factors:

Strength and stability of the polycarbonate panel under wind and snow loads;
Color, required level light transmission of polycarbonate;
Durability and resistance to mechanical damage.

In the simplest case, you don’t have to look for what thickness of polycarbonate is best to use for a canopy, and don’t take into account all the listed factors. You can just do it arched canopy made of monolithic material, as in the photo.

In this case, there is no need to look for a method on how to calculate a polycarbonate canopy; high stability and durability of even the thinnest monolithic plastic and metal carcass will provide a huge margin of safety. But this approach only works for small arched or flat canopies. Monolithic material is often used also in cases where it is required by the design of the canopy or lighting conditions, when the price of construction is not a determining factor.

For greenhouses, car and yard sheds, this design method will lead to an increase in the cost of financial resources, materials and effort. In many cases, using the simplest rules, you can effectively use cellular polycarbonate structures.

How to choose the right size for polycarbonate roofing

It's best to choose suitable option polycarbonate sheet when designing a canopy structure using specialized computer program. In this case, the program will display the exact thickness of the polycarbonate for the canopies and the recommended lathing pitch.

At home, the calculation of a polycarbonate canopy can be performed using a simplified scheme. First of all, you will need to determine the thickness of the honeycomb panel. Typically, panels with a thickness of 6 mm and 8 mm are used for arched and lean-to canopies; both versions of honeycomb plastic are highly durable.

Next, you can estimate the size of the polycarbonate sheet for the canopy using the given diagram of the dependence of the strength of the coating on the thickness of the polycarbonate sheet. It can also be used to determine the pitch of lathing under polycarbonate for lean-to canopy.

As can be seen from the diagram, best option pitch is within 0.6-0.7 m, with large values The effect of thermal expansion begins to take effect. That is, in hot weather, when heated, too thin a sheet sags between the rafters, and in severe frosts a characteristic cracking sound appears. This leads to the formation of cracks around the holes of the material fastenings.

Advice! When purchasing, you can ask the sellers what is the best rafter pitch to use for a given thickness of the honeycomb panel.

The thickness of the sheet and the type of polycarbonate must be selected based on the installation location of the canopy and the method of use. For example, 8mm thick material is perfect for car and yard canopies. It can also be used for canopies and canopies on the porch of a one-story house.

For multi-story buildings and areas where hail often occurs, it is best to use monolithic sheets polycarbonate. Icicles and medium-sized hail upon impact freely pierce a sheet of 4 mm thick honeycomb material, and for recycled plastic, a layer of 6 mm and even 8 mm is broken.

Optimal polycarbonate canopy designs

Most good option An arched carport with a polycarbonate roof is shown in the photo below. The design is based on a double-beam arch with vertical pipes - supports.

It is best to make a polycarbonate canopy with your own hands according to the drawings.

The advantage of this design is that the load on the sheathing and on the polycarbonate itself is balanced in any wind, snow or rain. Open circuit provides good ventilation space, so there is no overheating effect under such a canopy.

To avoid problems with thermal expansion, the honeycomb material is laid in sheets 1 m wide, with the obligatory use of compensation spacers. It is better not to install polycarbonate without washers, no matter how high-quality and certified the material is, the thermal expansion of the plastic will still manifest itself, and you need to properly compensate for it, otherwise the coating will stretch and will be blown out by the wind in “bubbles”.

For single-pitch flat schemes with a wooden frame, it is best to use profiled honeycomb panels or monolithic plastic. In this case, the roofing, due to its own increased rigidity, will strengthen the frame and rafter system.

Advice! Monolithic material is better in single-pitched sheds with a large angle of inclination. Flat roofs with molded glass make a lot of noise even in light rain.

To install a lean-to canopy on the facade of the house, we can recommend using the structure shown in the figure. This scheme very well protects the terraces from gusts of wind and is not sensitive to the pressure of snow cover of any thickness.

How to choose a color for the roof

One of the problems that has to be solved when planning a structure is related to tinting and painting the roofing material. Manufacturers offer enough big choice polycarbonate flowers for canopy, photo.

Often the problem of which color of polycarbonate is best to choose for a canopy is associated with the fear of a greenhouse or greenhouse effect, especially if light blue or colorless tones are used. Polycarbonate plastic blocks ultraviolet radiation well, but allows heat rays to pass through, so the layer of air under the canopy warms up very quickly.

If you like transparent and lightly colored polycarbonate brands, then it is best to make ventilation ducts at the top point of the structure. A small draft will remove excess heat.

For the color perception of human eyes, smoky, light green, bronze and yellow colors. They are not irritating and do not cause color blindness.

Conclusion

The choice of which polycarbonate is best to use for a canopy is always subjective and largely depends on the preferences and taste of the owner. Cellular brands are cheaper, but require care and proper design of the frame. Monolithic polycarbonate material It tolerates heat and frost well, has good external properties, but the roof is very heavy and quite expensive.

Polycarbonate roofing sheets are made from high quality thermoplastic material that is durable, ductile, unbreakable and light in weight. Compared to glass, it weighs 6 times less, and compared to acrylic glass - 3 times less. Polycarbonate roof is used in industrial, commercial And residential construction . Inherent light material weight avoids additional load on the structure.

Roofing material is available in a wide range color scheme And different textures, which allows you to create a unique and unique design. Moreover, unlike conventional or standard materials for roofing, most polycarbonate roofing materials are made from recycled materials, thereby significantly reducing negative impact on the environment.

Types of material

There are 2 types of PC for roofing - monolithic transparent And structured or cellular. Polycarbonate transparent sheets are either completely transparent or slightly tinted, and are used where maximum illumination through the roof is necessary - in greenhouses, solariums, attic windows, glassed terrace and on the patio. Sheets of monolithic polycarbonate for the roof must have a layer of protection against ultraviolet rays.

Unlike monolithic, cellular polycarbonate for roofing is less transparent and therefore finds use for more traditional purposes. Cellular PC is produced in a wide range of colors.

In terms of functionality, such material not inferior to metal roofing sheets, but unlike metal, it is not subject to corrosion, and its honeycomb structure provides additional insulation and sound insulation.

Cellular polycarbonate roofing is mainly used for industrial buildings such as: warehouses, flat or pitched roofs for verandas, gazebos, canopies and small residential buildings.

Featuring a rectangular tunnel structure with thin walls and a multi-layer structure that traps air between layers, honeycomb sheets increase thermal insulation and energy efficiency structures. The material is highly flammable, does not support combustion and does not emit toxic substances.

Cellular PC with thin protective layer on both sides of the sheet ensures high penetration rate daylight And 100% UV protection. Another feature of this type of polymer is its high elasticity; the sheets bend well without pre-molding, which is wide application in buildings complex shape, such as archways and domes.

Polymer available in different colors and invoices. The material is also produced in corrugated (profiled) form. Profiled polycarbonate roofing sheets typically come in wave-shaped sheets and have either a round or square outline to increase strength and allow water drainage.

Properties and installation features

All types of PC sheets have the following properties: heat resistance, resistance to any weather conditions and shock, flexibility, lightness and non-flammability.

Square or square structural steel pipes are used as a supporting structure for a polycarbonate roof. rectangular shape, depending on the construction project.

The sheets are usually installed between aluminum connecting profiles using rubber seals EPDM for waterproofing. This system is known as dry glazing.

Profiled or corrugated sheets, like metal sheets, are secured using self-tapping or self-drilling screws (STSD).

Innovative roofing materials

The quality of PCs is constantly improving thanks to technical and scientific innovations. Currently, new installation possibilities are being studied and products are being developed to provide the consumer with additional benefits. For example, roofing sheet with a combination of various additives and shades that block a significant amount of glare without affecting the quality of light passing through the sheet or its aesthetic appeal.

Corrugated sheets in transparent shades of bronze, grey, opal and milky white provide high UV protection, which allows them to be used for structures on outdoors such as: patio, pool deck and veranda.

Polycarbonate sheets with double UV protection have a high wear resistance. The discoloration in this type of material is no more than 4 delta units according to the yellowing index, while the discoloration of ordinary sheets is more than 10 delta units.

Another type of material in this segment is cellular polycarbonate, airgel filled. This type of product has maximum thermal insulation, excellent weather resistance, high light transmittance and increased impact resistance. Its thermal insulation properties are superior to three-chamber and double-glazed windows filled with argon.

The UV protective coating is applied by coextrusion during the sheet manufacturing process. This type of roofing is environmentally friendly and is used for glazing roofs in conservatories, eco-houses, lanterns, open structures and industrial buildings.

A similar energy-saving product is profiled extruded polycarbonate with a protective layer against UV radiation, which is applied by co-extrusion to outside material, and reflective particles are included inside the sheet. Material reflects up to 60% solar radiation and reduces the building's heat load, which in turn reduces the use of air conditioning and can reduce energy consumption by 10-30%.
