APPLICATION

• For pitched cold and warm roofs,
• For insulated wall applications.

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.
  

Note:

Do not leave the membrane unnecessarily exposed to weathering, high winds, excessive UV etc. as this may cause damage over time. If you must leave the membrane exposed for extended periods of time, consider the use of suitable temporary protection materials.
