POLIISO® SB is a yellow thermal insulation panel made of rigid, closed-cell PIR foam, expanded between two supports: the top one is made of bituminized glass fiber and the bottom one of saturated glass fiber. The panels declares λD values from 0.025 to 0.028 W/mK (depending on thickness) according to European standard EN 13165, compressive strength values ≥ 150 kPa; they are fit for applications below membrane by flaming with maximum operating temperatures of up to 110 °C and come in a standard size of 600 x 1200 mm. The panels are available in thicknesses of 30 - 160 mm. APPLICATIONS WITH POLIISO® SB : Hot roof below bituminous membrane; ventilated sloped roof insulationunder bituminous membrane; hot garden roof. Thermal conductivity 0,028 - 0,025 W/mK
