Polyvalley three-wall sheet adapts rectangle structure with air space inside which guarantees good thermal insulation and excellent resistance to crash stress. The external side is coated with U.V. protection (can be on both sides if required) warranting resistance to aging due to atmospheric agents and UV rays. With characteristics as: light weight, flexible, virtually unbreakable, highly light transmission, better heat insulation, flame retardancy ect. the PC multi-wall sheet can be widely used in various areas such as: agricultural green house, building wall, building roof, awning, swimming pool roof and so on.
Technical Features:
Polycarbonate Physical properties:
Light transmission:
The Polyvalley clear PC sheet can reach over 80% light transmission levels.

Light weight:
PC sheet has a very high stiffness to weight ratio. When using for building wall or roof, the support structures needs not be as heavy as in the case of traditional materials such as glass. This will save must cost. And installing will be much easier either.

Energy saving:
PC sheet has a better energy saving property. When using for green house, this characteristic plays a very important role, especially in cold areas.

Impact and damage resistance:
Damage to roof glazing can be hazardous and expensive. Using PC sheet can protect against hailstones, vandalism or accidental damage with an impact resistance.

Fire resistance:
The fire performance of Polyvalley PC sheet has been independently tested and certified up to Class B1 (Chinese national standard)
UV protected:
All Polyvalley PC sheet has a high performance UV absorption layer. It was co-extruded on the outer surface and can protect the sheet turning yellow and loss of strength.
