Product Introduction:
Polyisocyanurate Sandwich Roof Panel is also known as anti-leakage sandwich roof panel, polyurethane hard foam insulation panel, polyurethane composite panel, PIR panel. It is a polyurethane rigid foam as a thermal insulation layer of bimetallic surface, monometallic surface, non-metallic surface composite plate, it is a wide range of uses, high potential energy-efficient building envelope materials, but also a new type of energy-saving plate.
Product Features:
1. Energy-saving & insulation: The insulation effect of the same thickness is 2 times that of EPS board.
2. Flame retardant and fireproof: the combustion level reaches B1/B2.
3. Airtight & sound insulation: good sound absorption, it has a reducing effect on external sounds.
4. Waterproof and rustproof: large span, fast drainage, good waterproof effect; The screws are hidden and not easy to rust.
Product advantages:
The polyurethane Sandwich Roof Panels of Henan Panels Industry Co.,Ltd are fixed by concealed nails, and the panels are overlapped tightly and no fastening nails can be seen. The unique waterproof groove design can effectively prevent rainwater leakage and avoid the phenomenon of cold bridge.
Adopt 39mm wave crest / ribs, increase surface strength, easy to drain, reduce snow load and wind load by 170%.
Super flame retardant: the thermal conductivity is 0.023w/(m•k), which ensures better thermal insulation effect. In practice, this effectively maintains the heat absorption of the building, with huge economic benefits.
Panels' surface profile and thickness:
Sandwich Roof Panels consists of two outer metal sheets (Color-coated steel plate, stainless steel, aluminum plate or other) with stabilizing core of insulation sandwiched between them.The outer surface of the sheet can be flat(microribbed /plat/square wave/relief), corrugated or any specific design.Insulating material can be Polyurethane(PUF), Poly-isocyanurate(PIR), Rockwool or glasswool.
