How to Insulate your Garage Door

Difficulty: Easy • 7 Steps

Here we detail how to Insulate your Garage Door effectively, without professional or great expense.

This is a cost effective way to start enjoying your garage space. We use a highly reflective multifoil insulation to ensure you get the results you desire and can enjoy a more ambient temperature all year round.

By insulating your garage door you are preventing the cold bridging, via the door. This is the area of the garage that is most prone to cold bridging as it is metal, which is susceptible to this. However, if you use your Garage frequently – we would strongly recommend insulating your entire garage. You’ll benefit from a space that is comfortable all year round. Just press HERE.

Once you have installed the Garage Door Insulation Kit you will notice a significant decline in drafts and if present, condensation. Your energy bills will reduce, if you ordinarily have a heat source in there as you will require less heat energy to achieve the same temperature one insulated. A quick, simple way to make a massive improvement to your garage space.


Method Steps

  1. Clean the Garage Door

    The back of the garage door, that faces internally should be completely clean. It should be free from grease, dirt and debris. You should first use a brush to wipe away any of the loose dirt. Follow with a damp cloth and clean until there is no dirt. Allow the door to dry prior to installation. NOTE: This step is critical, as a clean surface will enable the multifoil to hold securely in place.

  2. Measure the Garage Door

    Measure the Garage Door, both width and height and note these dimensions. This will ensure you cut the correct amount of material.

  3. Roll the Insulation out and Cut

    Use the Multifoil Insulation Scissors and cut the insulation to size so that the first run covers the entire width.

  4. Install Double Sided Tape

    Install the double sided tape, at regular intervals distributing evenly on the door edge or bracing. Press down firmly on the tape to ensure you get a good secure bond between the multifoil insulation and the garage door.

  5. Remove the Backing Paper and Secure

    Start at the bottom right hand side and remove the backing paper, just before insulating. Ensure the insulation is pulled tort and then put pressure where the insulation meet the double sided adhesive tape.

  6. Repeat

    Repeat steps until you have full coverage, overlap each layer slightly to ensure continuous to get the best outcome. You may need to cut the multifoil insulation to ensure you do not have an overhang and that it is the perfect fit.

  7. Thermaseal Foil Joining Tape the Joints

    To finish, apply the Thermaseal Foil Joining Tape to the joins on the insulation (between each strip) We always advise using foil joining tape all around the edges too - at the top of the garage door tape along the insulation - but also wrap it over the edge of the garage door - for both support and to ensure an effective seal.
