ThermaFlex® is specially designed to friction fit between standard stud and joist spacings of 450mm and 600mm centres. It is easy and simple to install:

  1. Insert board flush against one side of the stud or joist, compress the other edge and ease the board into position.
  2. Should difficulty be encountered with non-standard stud and joist spacings, running a sharp knife down one of the longitudinal grooves can easily reduce the board width.
  3. ThermaFlex® eliminates wastage as the boards can be easily cut to length with a sharp knife or handsaw to fit between noggings. Off-cuts can be used for non-standard spacings.
  4. Where it is necessary to allow for electrical wiring or plumbing, holes can be easily cut into the board with a sharp knife.
