IPER SV are a range of vapour shield waterproof bituminous membranes, achieved with a woven non woven polyester of heavy grammage, impregnated with a polymer bitumen compound. The IPER SV range guarantees a good impermeability to water and furthermore, given the heavier weight compared to normal vapour shield bituminous membranes, capable to assure a higher resistance to U.V. rays and walkability during application. Furthermore the IPER SV membranes can be used as a “vapour shield” prior to the application of the insulation.
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).
