Frequently Asked Questions About Garage Door Insulation

Insulating the garage door can help you save money in a lot of ways. Here’s four reasons why we believe it is totally worth it to insulate garage door:

  • Lower Energy Costs. The temperature in the garage can impact the temperature in your house if it is attached to it. This can potentially result in higher electricity or fuel being used to keep your home cool or hot. Insulated doors can keep your garages significantly cooler in summer and warmer in winter.
  • Long-Lasting HVAC Equipment. Keeping your home cool in summer and warm in winter will not only save you on energy costs; it will also prevent your air conditioning or heating equipment from switching on and off that frequently.
  • Reduce Overall Stress on Your Car. Even if your car starts with ease in the cold weather, it does have a negative impact. Having insulated doors on your garages means your car will start in less extreme weather, helping keep the engines in a good shape and stress free.
  • Added Value for the Home. Insulated garages add value to your home’s worth, should you ever decide to sell it. It will show prospective buyers that they’ll be able to save on energy costs, equipment costs as well as extend the life of their car. It will also make the garages quieter, keep the pollution out more and make them look good and last longer.

The spring on your garage door is designed to carry a bit of extra weight although we have found in some cases doors need the spring and Motor adjusted. This can be carried out by having your door serviced by your local Garage Door Company.
No, this is the beauty of KoolDoor, the product is secured behind the lip of the panel, this gives it a tight secure fit without the use of adhesive.

Kooldoor is a rigid Closed cell hard Foam PIR that has an embossed foil both sides, we recommend you use a retractable snap off knife available at Bunnings the “Tojan“ brand is great for the job and easily slices through the lightweight KoolDoor.

The 25mm Trajan snap off knife is low cost ( under $12.00 with 5 extra blades) but very effective, simply extend the blade 20mm do the first cut and then extend 40mm to finish off the cut.
