Essential Tape for BreatherQuilt

Our Thermaseal WeatherProof Tape is essential for installing YBS BreatherQuilt.

Tape is an important ancillary item that should be used to tape and seal any vertical butt-joints on pitched roofs, when insulating with BreatherQuilt Insulation.

How to Install Thermaseal Weather Proof and BreatherQuilt

  • Firstly, install the BreatherQuilt Insulation across the rafters and staple in to place.
  • Secondly, install the next layer, overlapping by 100mm. Follow by using the in built tape (a tape that’s already attached to the BreatherQuilt, to secure this layer).
  • Finally, tape the vertical butt-joints only. This vertical joining method provides weather protection.

ThermaSeal Weatherproof Tape Roll Size

Thermaseal Waterproof Tape is available in rolls that are 50mm x 50m rolls.

How many rolls will you need?

For 10 rolls of YBS BreatherQuilt, we recommend 1 roll of Thermaseal Weatherproof Tape.

How to Fit BreatherQuilt over Rafter

  1. Installing BreatherQuilt

    Starting at the bottom of the roof, roll BreatherQuilt across the rafters and staple in place. Ensure BreatherQuilt is draped in-between each rafter as opposed to being pulled taught. It is important that a 10mm clear gap is formed at the center of all rafters. The gap required will be between the top layer of BreatherQuilt and installed tile batten.

  2. Fixing and Cutting

    Ensure BreatherQuilt is stapled at 300mm intervals, using min 14mm deep staples, or nails. BreatherQuilt can be cut with either Multifoil Scissors, or a Cutting Knife. Both the cutting tools, along with a Staple Gun & Staples are available in our Multifoil Fitting Kit.

  3. Overlapping

    Once the first run of BreatherQuilt is fully fixed, and is draping into the rafters, proceed by using the built in double sided adhesive to seal both layers together. Install the next layer of BreatherQuilt in the same manner as the first. Overlap the first and second layer by 100mm, ensuring the double sided tape is secure and sealed.

  4. Vertical Joints

    Where 2 layers of BreatherQuilt meet on vertical sections, we advise these layers to be butt jointed, not overlapped. These joints should be taped over with ThermaSeal Weatherproof Tape

  5. Final Detailing

    At the eaves BreatherQuilt should extend onto a suitable eaves carrier. Proceed with tile/slate battens and tile/slates.
