Product Features:
★Excellent Heat Insulation
PVC has a very low heat conduction coefficient of 0.325w/m.k, it is 1/310 of clay tile, 1/5 of cement tile, 1/2000 of 0.5mm thick color steel tile.
★Noisy Insulation
PVC roof sheet/tile can be widely used in frequent rainstorm,heavy wind areas.The roof can absorb the noisy from outside.
★Impact Resistance
Roof structure with hollow multi-frame,to ensure the hollow roof with more strong rigid and bending strength. In large temperature variation and frequent wind,rain,snow and wind area,there is no crack and damage by test.
★Stable Dimension
The expansion coefficient is 4.93×10-5mm/mm/℃,and the roof tile features bidirectional function in geometry.Even at high temperature difference,tile contraction will be digested by self to ensure size no change.
★Long Lasting Color
Co-extrusion technology on surface treatment to make sure long color lasting,even in strong UV radiation areas,even in large temperature variation and frequent wind ,rain,snow and wind.
★Waterproof performance
Single piece roof tile with large dimension,less lap joint and PVC roof tile with special screw to make sure all self-screw no rust,there is no leakage during rainy.
★Eco-friendly Design and Raw Material
All products do not contain radiation materials,all finished products can be recycled.No harm to human body.
★Quick Installation
Light weight with complete accessories,easy to be load and unload,single piece with large dimension more efficient and save cost during installation.
★Corrosion Resistance
Surface coated with ASA,body material is PVC .There is no chemical reactions when roof tile appear in corrosion conditions for 24 hours by test.It is superior choice for costal area and frequent acid area,chemical factory,etc.

Installation Notes:
The installation of PVC roof tile/ sheet should be done with a suitable purline spacing to avoid deformation, water leakage and cracking . The specific reference as follows:
1. PVC roof tile thickness ≤1.3mm , it is recommended that the inclined purline space is ≤600mm, and the round arched purline span is ≤700mm; the pvc roof tile thickness is 1.3mm to ≤1.8mm ,it is recommended that the inclined purline space is ≤700mm and the round arch purline space is ≤800mm; the roof tile thickness is 1.8mm to ≤3.0mm ,it is recommended that the inclined roof purline space is ≤800mm, and the round arched roof purline space is ≤900mm;
2.PVC roof sheet/tile horizontal overlap must be lapped 2 waves, the trapezoidal tile overlaps 1 wave horizontally, the longitudinal overlap length is greater than 250mm;
3. If it is fixed by self-tapping screws, it must be pre-drilled. The diameter of the hole must be larger than the diameter of the fixing screw by 2-3mm;
4.The purline space related with indoor ventilation temperature,please consult the relevant technical ;
5. Regardless of the type of PVC tile, the screws must be placed at the peak to prevent water leakage.
