SuperQuilt can be installed either vertically or horizontally, dependent on rafter height. Staple SuperQuilt to the rafters at spacing's of approx 300mm. Ensure SuperQuilt is pulled taught whilst rolling and stapling.
Ensure all SuperQuilt Insulation joints are overlapped by min 50mm. Tape and seal all overlaps using Thermaseal Foil Joining Tape. SuperQuilt can be easily cut using Multifoil Scissors or a Cutting Knife - Both available in our Multifoil Fitting Kit.
At the eaves, SuperQuilt is cut around the rafters, and sealed to the cavity wall insulation or wall plate. It is vital to fully tape and seal, to ensure that an airtight envelope is created.
Fix 25mm x 38mm battens at right angles to the rafters. Deeper battens can be used if preferred. Battens also must be fixed around the perimeter of windows.
The plasterboard is then screwed into the battens in the usual manner. When SuperQuilt is installed as the most internal insulation layer, there is no requirement for a foiled-back plasterboard. SuperQuilt will work as a high performing Vapour Control Layer, when taped and sealed using Thermaseal Foil Tape.
