Novia VC200 Reflective Air Leakage and Vapour Control Layer
Product launching soon
- High performance vapour control layer
- Low moisture permeability
All laps and edges should be fully sealed and taped. For vapour control layer installations, we recommend using double sided butyl tape with either 30mm or 15mm width. This is for all overlaps and fixings to frames. To fully seal the membrane and improve airtightness, use a single sided tape, such as aluminium foil tape or metallised BOPP tape to keep the overlap securely in place. Any screws and fixings must go through the double sided butyl tape, which seals around any puncture created by the fixings.
This will create an airtight installation. Further installation instructions regarding lap measurements can be found on individual product datasheets.
