SuperQuilt - Pitch Roof

  • Over Rafter
  • Under Rafter
  • Two Layer

Installation of SuperQuilt for over rafter applications and additional insulation products should be in accordance with the manufacturers certificate, fixing instructions and current good building practice.

SuperQuilt is applied directly from the roll either vertically or horizontally depending on the rafter height, pulled tight and stapled onto the rafters at minimum 300mm centres.

SuperQuilt should be overlapped at each joint by approx. 50mm and stapled onto the rafters, the joints should be sealed using YBS Foil Tape. Additionally, at the eaves SuperQuilt is cut around the rafters and sealed to the Cavity wall insulation or wall plate.

Parallel battens, recommended 38mm by 50mm are fixed to the rafters. Battens must always be fixed around the perimeter of windows.

A breather membrane is fitted in accordance with the manufacturers fixing details above the battens before tile battens and tiles. A vapour control layer should be fitted behind plasterboard to prevent any risk of interstitial condensation.

Installation of SuperQuilt for under rafter applications and additional insulation products should be in accordance with the manufacturers certificate, fixing instructions and current good building practice.

First Layer- Recessed between the rafters:

1. SuperQuilt is stapled to the first rafter.
2. SuperQuilt is recessed into the rafter void 38mm and fixed with staples or with battens.
3. The material is then fixed to opposite rafter as per instruction 2.
4. SuperQuilt is then wrapped around the rafter and the procedure starts again.

Once all the SuperQuilt is fitted, all joints should be taped using YBS Foil Tape.

Second Layer – Across rafter installation:

SuperQuilt is applied directly from the roll either vertically or horizontally depending on the rafter height, pulled tight and stapled onto the rafters at minimum 300mm centres.

SuperQuilt should be overlapped at each joint by approx. 50mm and stapled onto the rafters, the joints should be sealed using YBS Foil Tape. Additionally, at the eaves SuperQuilt is cut around the rafters and sealed to the Cavity wall insulation or wall plate.

When installing two layers of SuperQuilt a 38mm air space should be maintained between layers at all times.
