    Unroll the BreatherFoil Horizontally across the wall and staple it directly to the external timber boarding, at a minimum of 300mm intervals.

    Where a vertical joint occurs, ensure a minimum overlap of 100mm & seal using ThermaSeal Foil Joining Tape.

  4. Where A Horizontal Joint Occurs

    When rolling out the next roll above the first, horizontal joints need to be created, ensure a minimum overlap of 75mm, leaving the overlaps untaped.

  5. Attaching The Second Layer Of BreatherFoil

    Staple the BreatherFoil directly to the external timber boarding as before, at a minimum of 300mm intervals.
