Thermal insulation and acoustic absorption at the highest level.
Our iTEX ST insulation shells provide thermal insulation and acoustic absorption for a wide range of uses. Their low thermal conductivity, high sound absorption (ISO 10534-2), high mechanical strength and excellent physical properties are just some of the many benefits iTEX ST insulation shells deliver.

iTEX ST insulation shells are shaped in a special process based on the iTEX mat. With various additives included, a perfectly fitting solution is created that not only boasts improved thermal and acoustic performance but also greater mechanical stability. A 100% reproducible contour makes the skins easy to fit, while neatly sealed pinched edges completely eliminate common welding problems on the metallic lining.
