PVC Feature of Product

Strictly chosen material: Imported quality material is used and has passed the strict inspection and supervision of the company so as to ensure excellence of products.

Special durability: With the use of scientific anti-aging formula, each layer of material is subject to different kind of anti-aging treatment. The inner and outer UPVC layers are integrated ultraviolet absorbent, screening agent, antioxidant, modifying agent which work to effectively change the ultraviolet ray energy into heat energy and release it so as to improve anti-aging capacity of tile surface. The foamed structure of tile surface is formed by two-way tensile technique, and the high-tech interlayer foamed structure incorporates screening dye, working to block ray penetration again so as to prevent lower layer of tile free from ultraviolet ray which greatly extend the service life of tiles.

Acid, alkali & corrosion resistance: With reference to the application practice of UPVC roof material in recent 50 years in the world, the company incorporates its own unique production engineering and formula in light of the acid, alkali and corrosion resistant capacity of plastic. It ensures the leading quality of products.

Toughness & strength: The treatment by multiple two-way vertical tensile techniques ensures the rearrangement of molecular chain in an orderly way and thus increases the cohesion of molecules, providing the tri-ply compound foamed structure with higher mechanical property. The application of various modifying agents in the layers improves properties of UPVC, offering the tiles increased toughness and strength.

Thermal & acoustic insulation: The foamed structure of porous material interlayer has sound ventilating capacity, and the use of various modifying agents will effectively block the ultraviolet ray and reduce its heat transmission, enabling it to be top priority for heat insulating roof material. In the same way, when rain knocks tile surface, the sound wave will be refracted to the porous material and lead to air vibration. Then friction and reflection will be resulted by porous wall which decreases sound energy, generating sound insulation effect. Thus the product has excellent sound insulation function.

 Leak & wind resistance: The tile interlayer foaming will reduce or even remove the heat expansion or cold shrinkage coefficient. Pins shall be nailed into tiles tightly and circularly so as not to have leakage or relaxation in the nailing position that ensures excellent leak and wind resistance of tiles

Special high efficiency: Tiles can be nailed, drilled or sawn. The scientific overlapping method and wide tile are helpful to reduce interfaces occurred during installation, offering it a use efficiency as high as 93%, at least 8% higher than ordinary plastic tiles.

Installation Requirements:

★The roof truss structure adopts sectional steel or wood as purlin, the purlin is required to be flat without deformation, and two purlins must be in parallel with uniform span;
★For roofing tiles with thickness of 2mm, the purlin span≤700mm is recommended.

For roofing tiles with thickness >2.5mm, the purlin span≤800mm is recommended.

★ The transverse lap joint must be a complete lap jointed slope, the longitudinal lap joint length >300mm;
★ In the case of fixing by tapping screw, drill a hole in advance, the aperture must be 50% larger than the screw diameter, fixing by roofing tile hook is recommended. Screw and roofing tile hook can be used together, the screw must not be over-tightened, otherwise stress will occur, resulting in local crack on tile surface;

★The quantity of fix screws and roofing tile hooks must not be less than 5 sets per square meter of roofing tile;

★The slope gradient and the impact of perennial prevailing wind should be taken into consideration for roofing tile lap joint, the roofing tile arrangement sequence and pavement should be opposite to the local perennial prevailing wind direction, i.e. the exposed side lap joint of the roofing tile must be on the lee side away from the prevailing wind direction.
