Rooftec Breathable Roofing Membrane BBA Approved

Rooftec Breathable Roofing Membrane is a high-performance, BBA-certified solution designed to elevate the performance of tiled or slate pitch roofs. Whether fully supported or unsupported installations, this airtight and vapour permeable membrane is a reliable choice for various roofing applications, including warm and cold roofing setups, Scottish sarking boards, and timber and metal framed constructions.

Key Benefits:

  • BBA certified, ensuring quality and compliance.
  • Conforms to BS5534.2014 Annex A for added reliability.
  • Suitable for both warm and cold applications.
  • UV stable for up to 3 months, providing durability during roof construction.
  • Vapour permeable, allowing proper ventilation and reducing moisture buildup.
  • Serves as a waterproof membrane, ensuring protection from the elements.
  • Demonstrates resistance to extreme temperatures for enhanced longevity.
  • Rigorously tested through laboratory quality control to meet industry standards.

Installation:

  • Preparation:

  1. Ensure the ceiling is well sealed and free from any leaks or gaps.
  2. Check that the roof ridge height does not exceed 15 meters.
  3. Verify that the roof pitch falls within the range of 12.5° to 75°.
  4. Ensure the site altitude does not exceed 100m above sea level.
  5. Make sure there is no significant site topography present.
  • Placing the Membrane:

  1. Lay the Rooftec Breathable Membrane directly over the rafters on the insulating material.
  2. Stretch the membrane horizontally over the entire roof surface, ensuring even coverage.
  3. Provide a minimum overlap of at least 20cm at the ridge for proper sealing.
  • Tapered Lap:

  1. Use a batten lap of 345mm for pitches between 12.5° to 22°.
  2. For pitches over 22°, overlap the membrane sheeting by at least 20cm.
  • Securing and Sealing:

  1. Use membrane adhesive tape to secure seams, overlaps, butt joints, and any potential damage to the membrane.
  2. For connections to other substrates like masonry, use silicone or self-adhesive butyl tapes for a reliable seal.
  • Quality Check:

  1. Conduct a thorough inspection of the installed membrane for proper coverage and adhesion.
  2. Ensure there are no gaps or areas of weakness in the installation.
