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 mineralized glass fiber.

"HD" is the abbreviation of  "High Density", therefore the Compressive Strength is ≥ 200 kPa. The panels declares λD values from 0,025 W/mK 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 600 x 1200 mm. The panels are available in thicknesses of 30 - 160 mm.

APPLICATIONS WITH POLIISO® SB HD : Hot roof below bituminous membrane; ventilated sloped roof insulation under bituminous membrane; hot garden roof
