BreatherQuilt - Pitched Roof

  • Draped Detail
  • Counter Batten Detail

Installation of BreatherQuilt for pitched roof applications and additional insulation products should be in accordance with the manufacturer’s certificate, fixing instructions and current good building practice. Start at the bottom of the roof by rolling BreatherQuilt across the rafters and staple in to place. Tape a line of YBS double sided tape along the top edge of the material. Install the next layer of BreatherQuilt over lapping the material by 100mm. Staple as before and ensure the double sided tape is secure and sealed. Additional rolls should be butt jointed at the rafters, stapled as before and taped using YBS waterproof tape. BreatherQuilt can be cut using a craft knife or sharp pair of scissors. Staple at regular intervals (approx. every 300mm). Minimum 14mm stainless steel or galvanised staples are recommended. Horizontal jointing/taping – Overlap material by 100mm & tape using YBS double sided tape. Vertical jointing/taping – Butt joint over a rafter & tape using YBS waterproof tape. No personal protective equipment, clothing or handling required.

Starting at the bottom edge of the roof and working horizontally across the rafters, staple BreatherQuilt to the first rafter using minimum 14mm staples, BreatherQuilt should hang down between the rafters ensuring once tile battens are installed a clear 10mm drape is formed at the centre of all rafter spaces. At the eaves BreatherQuilt should extend onto a suitable eaves carrier. Proceed with tile/slate battens and tile/slates.
