Which corrugated polycarbonate for the roof is worth buying Wavy polycarbonate for the roof - dimensions and photos

You can assemble a good version of the roof for a small gazebo or a canopy, if you use corrugated polycarbonate for the roof. The size and shape of the transparent coating is somewhat reminiscent of a sheet of slate, but it is much easier and easier to lay it. Roofing corrugated polycarbonate for the roof will be more expensive than slate or metal, but a small overpayment is greatly offset by very good materials.

Advantages and disadvantages of wave polycarbonate for roofing

Arrangement of roof covering made of polycarbonate profiled sheet is a relatively new technology. Profiled polycarbonate looks stylish and modern, and therefore the temptation to use it as an unusual roof is very great.

So far, corrugated polycarbonate has not passed the test of time, like a seam metal roof or slate, and therefore all types of roof construction from profiled transparent material are a certain risk.

The main advantages of corrugated roofs

Of the positive aspects of using profile-type polycarbonate for roofing, the following can be distinguished:

  1. The roof is very expressive, and the wavy transparent surface looks quite unusual on a metal or wooden crate.
  2. The corrugated polycarbonate coating is relatively plastic, which means it adheres perfectly to the roof even in very hot climates. Strong wind gusts, as well as the pressure of thick snow cover, do not tear or push through the surface undulating structure.
  3. Due to the low degree of thermal conductivity, the profiled polycarbonate roof protects perfectly against heat and frost, and the corrugated surface creates ventilation channels to remove water vapor from the roofing cake.

  4. Polycarbonate corrugated sheet material is not afraid of chilled smoke gases and is afraid of detergents and contact with an aggressive environment, although hydrocarbon and alcohol solvents partially dissolve polymers.

Due to imparting a wavy-type structure to the monolith, it makes it possible to increase its degree of rigidity in the longitudinal direction several times, even reduces the sheet thickness. As a result, a thin and lightweight polycarbonate material laid on the roof will not "pop" under wind gusts, as can be done with honeycomb plastic.

Disadvantages of a corrugated polycarbonate roof

With all the advantages, profiled polycarbonate sheets remain a polymer, and therefore the organic base of a corrugated roof is much inferior to asbestos-cement sheets and metal.Among the minuses, we highlight the main ones:

  1. Which corrugated polycarbonate for the roof is worth buying Monolithic polycarbonate of the profile type quickly begins to collapse under the influence of ultraviolet radiation, and therefore, damage by means of a protective film will automatically mean either expensive repair work, or the destruction of a corrugated roof in 3-4 years.

  2. The expansion of the thermal type of plastic is several times greater than that of wood or metal, and therefore the fastening of profiled polycarbonate sheets must be performed according to a special scheme.
  3. The material is flammable and there are simply no methods to prevent combustion. Ignition can occur from a corner or poorly laid wiring and backlighting of a polycarbonate transparent roof.

The use of corrugated polycarbonate as a material for the roof is resorted to in a situation where it is required to provide more light in the space under the roof. This can be the roof of a winter garden, a closed glazed veranda, a canopy over a porch group.

In all cases, the wavy type material turns out to be more durable and practical than honeycomb types of plastics. To achieve this effect, under a roof made of flat or honeycomb plastic, you will need to lay reflective curtains, or use not the most convenient tinted coating marks.


Parameters of the profiled material for the roof

The sizes of corrugated monolithic polycarbonate are different. Despite the fact that such sheets are printed from the same plastic as flat, there is a difference between them, and very noticeable. First of all, the profile monolithic polycarbonate has high rigidity, "hot".

if a simple cast sheet of a flat type begins to deform already at +100 degrees, then the roof of a profiled type can withstand short-term heating up to +140 degrees.

Simply put, a corrugated roof made of a material such as polycarbonate will not “drive” in the summer when overheated in the sun, as it can with a large number of plastic coverings. In winter, transparent type profiled polycarbonate can be safely heated with an anti-icing cable or even boiled water, if you need to urgently free the roof from ice. With flat and honeycomb coverings, such experiments end in failure.

Wavy material is light enough, each square meter weighs from 1.

5 to 1.8 kg, depending on the size and height of the profile waves. Light permeability is from 90 to 92%, however, with a long stay on the roof, colorless material can turn yellow by 1-2%. Detailed qualities of corrugated material are shown in the table.

Dimensions of profiled polycarbonate

On the construction market, you can find about a dozen different shapes and standards of corrugated polycarbonate.

By thickness, the material can be divided into 3 groups:

  • Thin - from 0.08 to 0.1 cm.
  • Medium, that is, the middle factor - from 0.1 to 0 .

    15 cm.

  • High-strength coating - 0. 16-0. 2 cm.

The sheet width will range from 0.

48 to 1. 87 meters for different profiles. The higher the profile, the larger the transverse dimensions will be. For small sheds, roofs and outbuildings to the house, segments are used, the length of which is 1.5 meters.

If you cover a house with a minimum number of joints, you can purchase sheets with a length of 6 to 11 meters.

Varieties of profiled polycarbonate sheets

Usually, wave materials are divided into the main pair of types - with a classic wave section and a rectangular profile. In fact, there are many more types of corrugated polycarbonate. For example, a classic trapezoidal sheet or the same one, but with a greater height, is produced with a length of 1.5 to 11 meters and a width of 0.

75 and 1.2 meters, respectively. The thickness of the polycarbonate material is only 0.15 cm, and therefore it is used only for inserting unused roofs of sheds and buildings. An interesting solution would be the monolithic profiled polycarbonate Mini 32-9.

The height of the profile is only 0.9 m, but this is enough to reliably cover with a sheet with a thickness of 0.08 cm a roof section of 0.4 * 1. 2 meters.

Of the "slate" wavy options, Omega76-15 bkb Wаve5 can be used. 6 177-51. The latter option can be called a full-fledged roof covering that is suitable for use in small residential buildings.

Instructions for installing profiled material

There are some preconceptions in the application of corrugated polycarbonate coating. First of all, due to the high degree of plasticity of the material and its small thickness.

Under load, wavy polycarbonate can deform and lengthen by a large amount, up to 1 cm for every 1 meter of length.

Every home owner who first picked up profiled polycarbonate in his hands has a feeling that the strength of the material is not enough. But this is only an impression, because ondulin is almost as light and plastic, however, this does not prevent it from being used as a roofing covering for 10 to 15 operational years. Sheets with a low profile height are ideal for arranging a roof in a small gazebo or greenhouse.

Wavy polycarbonate for the roof Omega with a wave height of more than 1.

5 cm is quite realistic to use for a winter garden or greenhouse. The use of a transparent coating implies the absence of insulation material from the inside of the roof, and therefore the owners of winter greenhouse complexes use a combined roof. On the crate, a couple of layers of corrugated material must be successively laid. A cushion of air with a thickness of 8 cm is left between them. As a result, the roof will turn out to be very dry and warm, because most of the water vapor will not freeze to the roofing, but condenses and begins to flow down the depressions for drainage.

High profile polycarbonate is used mainly for pitched flat roofs. A polycarbonate sheet profile is covered with a greenhouse on the second floor or the attic slope is sheathed.

The corrugated surface helps to greatly simplify the laying process of polycarbonate. Together with the installation and purchase of a special bearing profile, which traditionally joins the edges of flat honeycomb and cast material, a simple wave overlap or trapezoid is used for sheet laying. The main thing is that the size of the overlaps corresponds to the recommendations for a particular wave type.

The number of profiled polycarbonate for the roof

After you select a specific option for polycarbonate coverage, you need to calculate the number of sheets. Unlike slate, polycarbonate profiled material is laid on the slope in long strips, parallel to the roof slats with gables. To ensure a reliable joint, the overlap must account for at least 9% of the sheet width. For this reason, the width is subtracted from the available size of the transverse type from 9 to 10% and the pitch size is divided horizontally by the resulting size.

Crate for corrugated sheets

Even the crate pitch is chosen for the width of the sheet.

Traditionally, the polycarbonate manufacturer gives recommendations about the optimal distance between the battens, but you can also use your own size. The main thing is that the central line of the overlapping zone of adjacent canvases is required on the axial beam from the lathing.

Attachment of waves

To fix the profiled polycarbonate sheet, try on the same attachment as for the honeycomb material. It is imperative to complete each self-tapping screw with an expansion joint made of soft rubber or silicone. After laying on the crate, the wavy-type canvas is straightened and leveled, and also connected to the adjacent sheet, and then attached by means of self-tapping screws, starting with the ridge and ending with the cornice bar.

On it, self-tapping screws are screwed into each profile depression. At the end of the fastening of the profiled type polycarbonate to the profile near the ridge and under the sheet along the eaves strip, it is required to mount the plugs.


Which corrugated polycarbonate for the roof is worth buying Bondarenko Semyon Stepanovich, 49 years old, Krasnodon : "The roof of the transparent type looks wonderful, but after the grandson installed the lighting, the house began to shine. In the evening everything is so beautiful that all the neighbors were envious and are already wondering how to properly lay the material."

Druzhkov Alexander Sergeevich, 60 years old, Moscow: "I didn’t even want to use wavy material for a country house at first, I laid more than 1000 squares on greenhouses, and used the rest for a shed.

I liked the appearance, made curtain glazing above the balcony.

I advise everyone, because as it turned out, the polycarbonate wavy covering on the roof is easier to repair than any other materials. For this, special varnish compositions are produced, through which the operating life of the roof can be easily increased to 20 years.

Viktor Pavlovich Bodyuk, Bobruisk: "My son began to cover the transparent wavy material and install glass heat exchanger pipes on the ridge.Now the house has enough hot water, and there is also an opportunity to heat the poultry house.



In terms of its parameters and quality of operation, a wavy polycarbonate covering for the roof is better suited than cast or honeycomb grades. The profiled material has excellent adaptability and easily withstands snow load and sudden wind gusts.
