Polyisocyanurate PIR core sandwich panel

plastic laminate facingroofwaterproof

Polyurethane is recognized as the most insulating material in the world,Wiskind use PU/PIR corial material to produce the Over Lap Type PIR PU PUF Roof Sandwich Panels. It has the advantages of best thermal insulation performance, class B fire resistance, light weight, non-toxicity, etc. It is widely used in the roofing of industrial steel structure buildings with high thermal insulation requirements, and the roofing of buildings in industries such as food and electronics. 1. Low thermal conductivity≤0.020. It has a high-efficient thermal insulation effect. 2. High percentage of close area ≥90% and low moisture absorption ≤3%. It has an excellent waterproof effect. 3. It adopts the unique concave-convex type which improves the tightness of the socket of the panel. High viscosity, high strength≥220 and good load resistance performance≥2450. 4. Excellent flame resistance level B. 5. Wide scope of temperature resistance. 6. The panel is even and stable. 7. The dimensional stability is good≤2. 8. It is a green and environmental-friendly product. 9. Easy and convenient construction. 10. Fast and quick installation. Wiskind selects the new generation of pentane-blown B1 PU-PIR foam as the rigid core material, which possesses an excellent thermal insulation and fire resistance performance. It boasts ultra-high temperature stability and fire protection rating, while is energy saving and eco-friendly with zero Freon emissions, thus able to be widely used in industrial buildings and cold storage projects.
