Underlays and vapour barriers

Underlays, vapour barriers/vcls & wall membranes

The Klöber adhesives, sealants and sealing collars which have been approved for the Klöber underlays and vapour barriers provide you with the full reliability of a single system. The adhesive and sealant products adhere perfectly to the Klöber membranes thanks to the coordination of the surface materials. In addition, regular internal and external inspections are conducted to check and ensure the product quality and suitability of the products for certain applications.


Permo® / Ecovent® vapour permeable underlays

Permo® vapour permeable underlays

Klöber's Permo® / Ecovent® roofing underlays are strong and flexible with a range that fits perfect for all pitched roofs. Being weatherproof, UV-stable, tear-resistant and anti-slip, even when wet, they guard against wind-driven rain and snow during and after roof construction, protecting the building structure from the moment it is installed.

Wallint® air barriers and vapour control layers

Wallint® vapour barriers

As even thicker layers of insulation are installed to comply with more demanding Building Regulations, so it becomes increasingly important to provide an air barrier and vapour control layer on the warm side of the insulation. Wallint® membranes have been especially developed for this purpose.
