Method Steps

  1. Clean Garage Door

    Firstly before applying any items, it is essential the garage door is fully wiped down. It is vital there is no dust or debris on the garage door, as this could affect the tape sticking on the garage door.

  2. Measure the Garage Door

    Next step is to measure the length and height of the garage door. This is important the correct dimensions is cut for when the insulation is fitted. Note - The insulation is 1.2m in width.

  3. Cut the Multifoil Insulation

    With a cutting knife, or Multifoil Scissors, next cut the insulation to the correct size. Usually we recommend to roll the insulation horizontally on the garage, so usually the length needs to be cut, compared to the width.

  4. Stick Double Sided Tape on Insulation

    We would recommend fixing Thermaseal Double Sided Tape directly on the insulation. Run the tape completely around the perimeter of the cut-to-size insulation piece. Aswell as around the perimeter, there is no harm to go overkill on the Double Sided Tape. You may want to create a cross also with the Tape. Once you stick the Double Sided Tape on the insulation, you should be able to peel of the sticky back, exposing a sticky side ready to fit on the garage door.

  5. Stick the insulation piece on the garage door

    Once the insulation has been fixed with the tape, it is ready to stick directly on the clean garage door. Start with the bottom half. Ensure the insulation is well installed on the door, to get a secure bond.

  6. Repeat steps 5 and 6

    Once the bottom half has been fitted, you need to repeat step to fit the bottom half.

  7. Seal the overlaps with Thermaseal Foil Tape

    The final step is the seal the overlap with Thermaseal Foil Joining Tape. To gain an even better seal, it is also recommended to seal around the perimeter.
