Product data

To enable vapour retarders and other materials to fulfil their purpose as airtight layer in a construction these must also have air-tight joins at cable entry points. Warm air finds its way inside a building component through even the smallest of holes in the vapour retarder, where it then condenses. AIRSTOP Cable Sleeves, sealed airtight with age-resistant sealing plasters, guarantee that the construction is wind-tight and air-tight.

Processing guideline


Pull the rubber sleeve over the conduit and attach to the air-tight layer (vapour barrier, OSB,…) by the integrated sealing plaster. The diameter of the sleeve selected must have the appropriate dimension for the conduit entry point!
Talcum powder or a lubricant can be used if necessary to ease the feeding of the cable/pipe through the sleeve.
The materials used must be free from dust and grease and substrates must be dry and supporting.
The greater the pressure applied, the better the performance of the adhesive tape.
On highly porous and very absorbent substrates such as concrete, plaster, untreated steel or raw wood, we recommend pre-treatment of the substrate with our ISOCELL Primers.
