How do I lay Therma-Foil?

Therma-Foil should be placed foil side into the house. For added effect place the second layer of foil outward to reflect cold away (and in the summer heat).

  1. Firstly, measure out the area where the Therma-Foil will be installed.
  2. Measure out and cut the roll Of therma-Foil to the correct lengths to fill the room. Note, we recommend a slight overlap of about 50mm.
  3. Place down, with the reflective foil side towards you.(face up)
  4. Once in place, tape Therma-Foil as and where needed using Duck/Gaffer tape.
  5. Check your insulation is flat and there are no air bubbles anywhere. If there is it’s easy to just push them out.
  6. Staple the insulation onto the floor wall (wherever you are placing it. We recommend that you should staple Therma-Foil every 16” to 24”. Keep it tight to ensure it stays flat.
