Kingspan Nilvent is a breathable membrane suitable for use in unventilated pitched roof and timber frame wall applications. The membrane is waterproof, non-tenting and airtight at normal building pressures.
Key points :
Waterproof - can be used as a temporary roof covering
Non-tenting and lightweight
Airtight at normal building pressures
Excellent water vapour permeability
Strong - excellent nail tear and tensile strengths
Application: - Timber frame walls: Kingspan Nilvent can be fixed to a timber frame wall either horizontally or vertically.
- Slating & tiling: Slating and tiling over Kingspan Nilvent is exactly the same as on any other pitched roof except that, in some instances, the slate / tile battens (if required) are fixed to the previously applied counter–battens.
- Rooflights: please refer to the instructions provided by the rooflight manufacturer. In the absence of manufacturer’s information, cut and fit Kingspan Nilvent neatly around the rooflight kerb, with an upstand of 50mm.
