GreenPIR®CAL heat-insulating boards consist of a heat-insulating core made of rigid PIR foam.
The boards are protected on both sides with a gas-tight fiberglass layer.
Features of GreenPIR®CAL panels:
High compressive strength (20 t/m2)
Rigidity: maintains thermal insulation characteristics for many years
Low weight: Relatively thin profile and low density of the panel material reduce the overall weight of the roof, which reduces the cost of the supporting structure by 15–20%.
