POLIISO® SB-HD 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.
"HD" is the abbreviation of "High Density", therefore the Compressive Strength is ≥200 kPa. The panels have nominal λDvalues of 0.026 or 0.028 W/mK (depending on thickness) according to European standard EN 13165, 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 600x1200 mm. The panels are available in thicknesses of 30-120 mm.
APPLICATIONS WITH POLIISO® SB-HD : Hot roof below bituminous membrane; ventilated sloped roof insulationunder bituminous membrane; hot garden roof.
