The advantages of Polycarbonate Roofing Sheets

Polycarbonate Roofing Sheets have a number of properties which, in full, does not possess any of the other transparent materials used in construction, namely:

1. Emergency light, low specific gravity (Polycarbonate Roofing Sheet weighs 16 times less than glass and is 6 times less than the acrylic of the same thickness, which significantly reduces the cost of supporting structures).

2. High impact strength (polycarbonate, as a viscous polymer, 200 times stronger than glass and 8 times stronger than acrylic plastic). The panels of polycarbonate, not broken and do not crack, and, consequently, sharp splinters on impact.

3. Polycarbonate panels can withstand significant wind and snow loads, do not tear like plastic film, which makes them the best material for greenhouses. Thus, the panel of polycarbonate are resistant to shock and hail are safe glazing.

4. High temperature resistance (the properties of polycarbonate little dependent on changes in the environment, and the critical temperature at which the material becomes brittle, are outside the zone of operation).

5. Low flammability (the coefficient of F-1), did not ignite in a fire, is not conducive to its spread and temperature fracture poses no danger to life. Polycarbonate Roofing Sheet under the influence of the flame melts with the formation of nonconducting arachnoid fibers and, unlike other plastics, not accompanied by the release of toxic substances.

6. High insulating properties, low thermal conductivity (heat transfer coefficient 3.4 W / sq and the resistance of the transmission of heat is higher than that of conventional single-layered glass, which reduces energy consumption for heating and cooling by about 50%).

7. Excellent sound insulation (sound absorption significantly compared with single-layer materials by quenching of the sound wave, which passes from one medium to another). This allows you to successfully use Polycarbonate Roofing Sheet as noise barriers.

8. high light transmission (transparency – up to 86%, good dispersion of light, no shadows, the gain due to the reflection on the partitions).

9. The bending strength and tensile strength.

10. Wide operating temperature range: -40 to +120 ° C, which allows the use Polycarbonate Roofing Sheet in different climatic conditions. The outer surface of the panel is covered with a layer that protects against UV radiation. This layer absorbs the ultraviolet portion of solar spectrum and provides a constant mechanical and optical properties over many years of operation.

Polycarbonate Roofing Sheets   Light transmitting properties

Optical transmission of transparent double-layer polycarbonate panels reaches up to 86%. In addition to the transparent panels are manufactured by white panels with varying degrees of light transmission: from translucent “opal” from Transmittance 50-75% and the maximum saturated white “sain” by a factor of 20-30% and completely opaque silver, will ensure optimum performance for specific applications. Also produced transparent honeycomb panels, tinted in blue, turquoise, red, gray, green, and “bronze” with a coefficient of light transmission depending on the thickness and structure of the panels 25-45%.
Cvetopropuskanie panels polycarbonate SUNLIGHT ® is practically not reduced during long-term operation on the street.
Hard ultraviolet radiation (range of less than 400 nanometers), harmful to human, plant and equipment, virtually does not pass through the polycarbonate sheet. The transmission of useful light – optimally. The transmission of hollow polycarbonate rays, located in the far infrared part of the band spectrum (5000 nm) is minimal, so that the heat emitted by objects in space has protected remains inside, creating a “greenhouse effect”, which is an additional advantage of using this material as glasshouses , greenhouses, conservatories, etc.
All types of polycarbonate panels SUNLIGHT ® favorably scatter light, repeatedly penetrating the rays of light from all surfaces (the top layer, the ribs, the bottom layer). Relaxing subdued light yield polycarbonate panels “bronze” color. The maximum effect of light scattering is achieved in the panels “Opal”, which to highlight the fluorescent lamps provide a uniformly illuminated “light screen”.

Polycarbonate Roofing Sheets Insulation properties

Polycarbonate Roofing Sheet is 200 times stronger and 6 times lighter than glass and can be used as a substitute. Air layer in the polycarbonate panels – an excellent thermal insulator. Even the thin panel polycarbonate 4mm thick almost two times higher than the degree of insulation of simple glazing. In window glass of the same thickness of the heat transfer coefficient 6.4 W/square.mS.
Panels SUNLIGHT® 8mm thick comparable with glass, and 16-25mm panel exceeded those of the insulating glass units, triple glazing. In this design from polycarbonate do not break, have protection from ultraviolet rays and weigh on the order of less structural glass, which makes it possible to simplify the framework.
The winners and their ease of transportation and installation, and if there is a necessity and dismantling (specialized polycarbonate and aluminum profiles can also produce ready-made designs).

It burns only in an open flame and is self-extinguishing.
Polycarbonate Roofing Sheet does not contribute to the spread of combustion, it does not form burning droplets, the combustion occurs only swelling of the material and it is easy to thread, time to get cold before the fall.
And finally, formed by melting polycarbonate panels contribute to the smoke-hole in case of fire.
Polycarbonate Roofing Sheets is not a roofing material for residential and materials for building evacuation routes people are prohibited from using polycarbonate sheets for this purpose.

Polycarbonate Roofing Sheets   Durability in extreme weather and climates

Polycarbonate Roofing Sheets SUNLIGHT® “great feeling” in the temperature range from -40 ° C to +120 ° C, preserving all the mechanical and optical properties. To eliminate the harmful effects of ultraviolet rays on the material used method of surface coating a transparent UV-stabilizing layer on the outer side of your panel. The thickness of the UV-protection is 30-50 microns. Lifetime polycarbonate panels SUNLIGHT with all the recommendations of the manufacturer is 6-10 years.
When using products from hollow polycarbonate in places where the product is subject to mechanical stress, it is necessary to use sheets of thickness not less than 16mm.
Please note that the most important condition for long life Polycarbonate Roofing Sheets SUNLIGHT® is the observance of all rules on storage, transportation, installation and subsequent operation of the material. The buyer alone is responsible for deciding that the finished product of the hollow polycarbonate is suitable for a particular purpose, and that the real operating conditions are acceptable for this product.

Polycarbonate Roofing Sheets Operation and maintenance

To clean sheets from contamination or removal from the surface of the material accumulated on it during the operation of dust and dirt, we recommend using a soft cloth or sponge, pre-soaking it in warm soapy water or detergent solution (18) .
Important: not use detergents, which include: alkali salts, aldehydes, phenols, ethers, chlorine, ammonia, various amines, aniline, acetone, methanol and izopropanal, as well as various solvents! Also it is impossible to clear polycarbonate panels using a knife or other sharp objects, because this can cause damage to the UV protection on the leaf surface and, consequently, to reduce its service life.

General principles of montage

Hollow polycarbonate panels SUNLIGHT set so that the side inscribed with the protection from ultraviolet rays, the installation was always turned toward the sun. Designation is packaging film (1) . UV protection is intended to eliminate the harmful effects of sunlight on the polycarbonate and maintain all of its mechanical properties during the period of operation. Prior to the installation of hollow sheets should be stored and transported in their original packaging in a horizontal position. Never store sheets in direct sunlight or without a covering from rain (2) . Do not tread on sheets or walk on sheets of polycarbonate at any time.
Cutting panels SUNLIGHT 4 mm thickness can be of special construction or layout knife with retractable blade. When cutting sheet polycarbonate protective film must remain intact, preventing the formation of scratches. For cutting thicker sheets used high-speed circular saw with a focus, equipped with blades with fine teeth undiluted hard-faced (3) . We recommend using the saw at a rate not less than 3200 rpm. Sheets with the need to firmly fix to prevent vibration. After completion of the procedure to remove residual dust and small chips to the edges sheet compressed air or a vacuum cleaner.
To prevent the formation of condensation inside the panel and the dust falling into the cell during its operation, it is necessary to seal the installation of open channels of special aluminum sealing tape (4) – the top of the continuum, from the bottom of the perforated. The solid tape (5) protects polycarbonate panel from entering its water, dirt, insects, etc. Punched tape (6) restricts the penetration of dust in the bottom end cell panels, not interfering with the removal of condensation of moisture. For timely and unimpeded withdrawal of already formed inside the honeycomb panels of condensate, it is necessary during installation to give them an adequate slope, and along the bottom edge to provide drainage channels.

 

Bending polycarbonate panels Plastilyuks permitted only along the channels, ie along the long side of the sheet. The bend radius should be 175 times the thickness of the sheet (7) . Recommended steps for installing load-bearing pillars of the longitudinal frame for polycarbonate sheets of thickness 6-16mm is 700mm, for 25mm thick sheets of 1050mm (plus clearance for mounting profile between the panels). The distance between the lateral bracing shall be calculated by a qualified technician according to the angle of inclination of the roof, the thickness of the polycarbonate sheet, as well as expected wind and snow load (kg/m2), and can range from 270mm to 2000mm.
Montage of hollow polycarbonate SUNLIGHT can be made as whole sheets, and the elements, equal in width to the distance between the bearing longitudinal supports (mounting profiles). In the first case, fixing the sheet is produced for each cross crate with screws or wood screws. To do this in the future duty attaching to the frame to drill a Polycarbonate Roofing Sheet hole diameter should be 50-70% larger than the diameter of bolts or screws are used – to account for the compression and expansion of the material. The recommended distance between the points of attachment – approximately 300mm. In the second case, the width of up to 600mm and the absence of wind, it will be enough to fix the panel using the mounting profile and bolts only in the first and the last crate. For drilling the holes, use the new steel drill. Drilling is made solely between stiffeners polycarbonate panels, avoid the strength of the sheet. In this case the recommended minimum distance from the hole, (places bolting) to the edge of the sheet must be at least 40mm (8) .
Before the installation of approximately 50 mm apart for the protective film from all sides of the sheet so that it does not come under mounting profiles and subsequently easily separated from the surface of the sheet (9) . The edges of the panel polycarbonate Plastilyuks deepened the grooves or profiles by not less than 20mm, which provides for the introduction of the locking area for more than two stiffeners. It should not embed the worksheet in the assembly profiles until it stops, and keep up to 5 mm space between the edge of the sheet and the inner wall profile (10) . This distance allows the movement sheet polycarbonate due to thermal expansion of material during seasonal temperature fluctuations (3-5mm per meter).
Installing the panels SUNLIGHT by using the original polycarbonate profiles SUNLIGHT ®: connecting – HP (11) , Wed (12) and trim UP (13) . These profiles are used for mounting the vertical frame structures, pitched roofs and small roofing over unheated rooms. To prevent formation on the snow covered bags, the optimal slope pitched roof should be 30-40 °.

 

Important: can-type polycarbonate profiles HP and UP are no assembly and are not intended for attachment to supporting structures! They serve only to compound polycarbonate sheets together and seal the joint. The extraction of water to be sucked into the profile at the junction of the panels produced by grooves provided in the base connecting profile. Of these, water flows into the edge profile, which shows the limits of design.
If necessary, at the joint panels polycarbonate Plastilyuks, to improve sealing can use silicone filler (14) .
Important: prohibited from using any sealants akrilosoderzhaschie! Do not lubricate the various oils and greases the site of injection of polycarbonate sheets in the profiles, because This leads to the destruction of the material at the junction.
For production of large surfaces and creating arches should be applied as a mounting detachable polycarbonate Profile NDS (15) . To fix the lower base part of the metal supporting structures necessary wood screws at 15mm longer than the thickness of the wall profile. Typically, the mounting base part of the HCP profile using screws 6,3 x 6,3 x 19mm or 25mm. In view of the fact that the screw is in the body profile and protected from atmospheric moisture, sealing washer is not required. To attach to a wooden crate using screws without a drill diameter 5,5 – 6,3 mm.
To seal the perforated panels in polycarbonate holes and load distribution in their places of attachment to the supporting structures needed as lining for bolts to use special plastic washers SUNLIGHT® diameter not less than 20mm with a rubber or neoprene gasket (16) . This makes it possible to reduce the pressure on the sheet and prevent the destruction of polycarbonate. This is not to screw up the bolts too tightly, it is necessary to ensure “free running” panel (17) . Also, you can not use seals made of soft PVC.
After completion of installation of panels polycarbonate Plastilyuks should immediately remove the protective film from the entire surface of the sheet.

 

The manufacturer is not liable for damage to finished products of polycarbonate that has occurred because of improper storage, transportation, installation and use of the material.
