Novia FR Roof and Wall Breather Membrane is a versatile, low cost fire class B-s1,d0 breather membrane for use in all pitched cold and warm roofs, and insulated wall applications, allowed for high rise buildings.

INSTALLATION
To walls

  • Work from the bottom moving upwards and ensuring there are minimum overlaps of 100 mm on the horizontal joints.
  • Do not begin a vertical lap joint within 300 mm of a corner,
  • Vertical laps should be at least 150 mm.
  • Ensure the bottom timber is also protected by an overlap.
  • Fix at suitable intervals with galvanised nails, stainless staples or similar permanent fixings.
To roofs

  • Work from the bottom moving upwards and ensure there are minimum overlaps.
  • The membrane should be overlapped 200 mm on each side of the ridge.
