INSTALLATION

To walls

• Ensure upper layers overlap lower layers.
• 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

• Ensure upper layers overlap lower layers.
• 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.
• All vertical overlaps must be situated on a rafter and must be sealed.
• Fix at suitable intervals with galvanised nails, stainless staples or similar permanent fixings.
• At any entry points for services (soil pipes, vents etc.), ensure that the membrane is properly sealed.
• Use of Novia breather membrane tapes.
• Ensure that for wall or warm roof applications, a vapour barrier is installed on the warm side of the insulation.
