To achieve a proper airtightness, you have to seal all connections and perforations professionally.
KONTEX Airtight Sealing Patches are made for the secure sealing of wires, cables and smaller pipes, which perforate the vapour membrane.
By using a condom-like technology, our Airtight Sealing Patches don´t have protruding grummets to ensure the airtightness, as seen on competitors products.
Save time and ensure a full airtightness by using the self-sticking patches instead of doing handicrafts by using tapes or adhesives.
Each patch has a size of 150x150mm.
Other perforation diameters are available on request.
