Humidity-variable sealing strip
Advantages
- Time-saving installation: vapour check strips are pre-cut
- Also suitable for building components with short-term moisture loading
- Construction in adherence with standards: for airtight sealing in accordance with DIN 4108-7, SIA 180 and RE 2020
- Protection in rough everyday building site environments thanks to robust fleeces
- Excellent protection for building components thanks to humidity-variable diffusion resistance
- Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme
Areas of application
Strip for sealing over joints, e.g. at floor joints with concrete floors/ceilings, on wood-based panels, for use on the middle purlin (between middle purlin and rafters) for sealing joints with adjacent airtight membranes, or as a repair strip for sealing leaks on roofs, walls, ceilings or floors.
