Modern materials are increasingly being used in construction. So polycarbonate finds more and more areas of application. If earlier it was used for the construction of partitions, greenhouses and decorative elements, now polycarbonate has gained popularity as a roofing material.
It is used for roofing gazebos, terraces, awnings and canopies over the entrance.
Polycarbonate is a material that allows you to embody the most daring ideas.
The advantages of polycarbonate are:
The disadvantages of polycarbonate include the fear of UV radiation when damaged.
The peculiarity of mounting polycarbonate is that the mounting is carried out with the help of special self-tapping screws using special washers. With the obligatory preliminary drilling of holes with a large diameter, which will avoid deformation of the polycarbonate when the temperature changes.
Monolithic polycarbonate has a thickness of 2 to 12 millimeters and the main advantage of a monolithic polycarbonate roof is its high strength.
Monolithic polycarbonate with a thickness of 12 millimeters withstands hammer blows and is considered vandal-proof.
Monolithic polycarbonate is used for roofing any roof configurations.
Cellular polycarbonate has a cellular structure, due to this it has a low weight ...
Cellular polycarbonate consists of several thin sheets of polycarbonate connected by perpendicular stiffeners. This polycarbonate structure provides high mechanical strength, yet the material remains lightweight.
Cellular polycarbonate is used in the manufacture of various arched and domed structures, as it is easily applicable for complex structures.
Has a wide range of colors and shades. The size of the sheet of two types is 2 meters by 6 meters or 2 meters by 12 meters with a thickness of 3 millimeters to 32 millimeters.
It is not difficult to make a polycarbonate roof.
Selection of material for the manufacture of the roof frame
There are many materials for the construction of polycarbonate roofs.
The main criteria for choosing are the main stylistic idea, they also take into account the snow and wind load.
When building straight roofs, as a rule, wood is used, where the rafter system consists of wooden blocks and boards, on top of which polycarbonate is laid.
For the construction of roofs that include domed structures , as well as arches , use a metal profile: steel or aluminum.
The use of one or another metal is determined by the type of structure. Aluminum is used to build lightweight buildings. For the structures of bulky buildings, metal is used that carries a large snow load.
For fastening to the polycarbonate profile, use special self-tapping screws with a sealing washer. The joints of the sheets (joints) are connected using an H-shaped profile.
The design of straight roofs can be different one, two, three, four pitched.
The advantage of these roofs is getting natural light, which creates the feeling of open space. The disadvantage of will be that such roofs cannot be insulated without losing the main advantage. As a result, more often such a roof is used for the construction of country houses, terraces, gazebos.
The rafter system will depend on the type of roof.
A special feature is that polycarbonate is lightweight and rafters can be erected from a board 40 millimeters thick. Distances are made based on the width of the polycarbonate sheet. Before laying polycarbonate, it is necessary to process the wood with antiseptic and fire retardants.
Cutting of polycarbonate is performed locally.
It must be ensured that the directions of the rigidity coincide with the direction of the roof slope.
This is done so that condensate collecting from the inside of the roof can be easily removed. It is also very important during installation to orient the polycarbonate with the UV-protected side outward, you can determine the side by the marking and protective film.
Before fixing the polycarbonate, holes are drilled in it after preliminary marking 2 millimeters larger than the diameter of the self-tapping screw, when tightening the screws, it is necessary to achieve so that the washer fits snugly against the material, however, the material should not deform.
The transverse joints are fastened using H-profiles, and the longitudinal joints are glued with a sealing tape to prevent the appearance of condensation inside the polycarbonate sheet.
The ridge is made from a special ridge profile.
For arched and domed roofs, as a rule, square pipes are used, from which the necessary circles and arcs are bent.
The fastening of polycarbonate to the profile is identical with the fastening to the tree.
