IPER T 500

Vapour retarder bituminous membrane

IPER T 500 are vapour retarder bituminous membranes, made from a woven non woven polyester impregnated with a distilled polymer bitumen compound. IPER T 500 guarantees a good breathability and assures to the structure a very good level of vapour permeability, even though it provides a sufficient water impermeability (on roofs with not less than a 40% slope).
