Method Steps

  1. Installing over existing joists

    Start by removing the existing floorboards to expose all joists. We then recommend running the multifoil perpendicular to joists and cutting at each end, allowing enough material to recess the quilt into the joists.

  2. Recessing Multifoil

    To save on headheight, you can now recess the multifoil into the joists. We recommend using a 50mm batten as a guide and stapling along the top and sides of each batten. If preferred you can use our Multifoil Saddle Clips.

  3. Taping and Sealing with ThermaSeal Foil Tape

    Next tape and seal around the perimeter with ThermaSeal Foil Joining Tape. This will prevent drafts from rising through the flooring. We recommend overlapping each layer of Multifoil by 50mm and leaving the overlaps untaped, to allow the timbers to breathe.

  4. Laying Floorboards

    You can then proceed to install the floorboards back over the joists and insulation. This will then have created an air cavity on either side of the insulation.
