Method Steps

  1. Installing SuperQuilt

    SuperQuilt can be installed either vertically or horizontally, dependent on rafter height. Staple SuperQuilt to the rafters at 30mm intervals. Ensure SuperQuilt is pulled taught whilst rolling and stapling.

  2. Overlapping & Taping

    Ensure SuperQuilt Insulation joints are overlapped by min 50mm. Ensure overlaps are fully taped and sealed using Thermaseal Foil Joining Tape (75mm x 50m). SuperQuilt can be easily cut using Multifoil Scissors or a Cutting Knife - Both available in our Multifoil Fitting Kit which can be purchased to the right hand side of this guide.

  3. Eaves Detailing

    At the eaves, SuperQuilt is cut around the rafters, and sealed to the cavity wall insulation or wall plate. It is vital to ensure fully taped and sealed, to ensure that SuperQuilt acts as a high performing Vapour Control Layer.

  4. Installing Counter Battens

    Fix 25mm x 38mm battens underneath SuperQuilt. This is commny installed horizontally. Deeper battens can be used if preferred or if your U-Value Calculation recommends to. Battens also must be fixed around the perimeter of windows and doors.

  5. Internal Finish

    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.
