THERMAL INSULATION PANELS
The termPIR® BWS insulation boards comprise of a PIR rigid foam thermal insulation core. The boards are protected with gas-permeable lining from glass reticular ﬁbre (WS) on one side and with lining from glass reticular ﬁbre impregnated with bitumen (BT) on the other side. The intended use of the board are: build Up Roofs [BUR] – Flat & Green roofs, mechanically fastened and build Up Roofs [BUR] – Flat & Green roofs. With reaction to ﬁre (of the product as placed on the market): F Class, compressive strenght at 10% of deformation, σ10: for (20 ≤ d < 30 mm): ≥ 120 kPa, for (30 ≤ d ≤ 250 mm): ≥ 150 kPa and declared heat transfer coefficient for lining, λD: for (20 ≤ dN ≤ 80 mm): 0,026 [W/m·K], for (80 ≤ dN ≤ 120 mm): 0,025 [W/m·K].
