The System PRT and System COP expanded polyurethane panels, depending on the type of polyurethane insulating material used, are certified for various levels of fire reaction, including B-s1,d0, B-s2,d0 and B-s3,d0.
Another important result obtained for polyurethane foam (PUR) and polyisocyanurate (PIR) roofing panels, in the fire reaction field, is the BROOF (t3) rating (external fire exposure reaction), according to the UNI EN 13501-5 method.
The System MNR Fibra and System CPT Fibra panels have instead obtained the A2-s1,d0 fire reaction rating.
