Is It Worth It to Insulate a Non-Insulated Garage Door?

Insulated Garage Door

You’re wrapping up your garage renovation project – you’ve added insulation to the walls and the ceiling to help reduce heating and cooling loss and utility costs. Now you’re contemplating the garage door. It’s not insulated. Is it worth it to go ahead and cover it in insulation, or should you replace it with a new door?

You can insulate a non-insulated garage door, but there are a few things you should know. If you opt to move forward, there are at least two ways that you can achieve your goal.

Mineral Wool

Mineral Wool Blanket

One option is to use mineral wool blankets. You can pick these up at most any renovation or construction material store, and the kit includes both rolled sheets of mineral wool, as well as a plastic, reflective film. You’ll spend between $75 and $100 on materials with this option.

Polystyrene Panels

Another option is to use polystyrene insulating panels. You’ll find these available in most big box DIY stores, and the kit is usually designed for a single garage door that’s between eight and nine feet in width. Note that polystyrene panels are flammable, and you’ll need to cover it with an inflammable material to prevent the risk of fire.

So, as you can see, it is possible to insulate a non-insulated garage door. However, there are some downsides that you should be aware of. For one, adding insulation to the garage door isn’t going to stop cold from seeping through the door. Non-insulated garage doors lack thermal breaks between the interior and exterior sections. So, be prepared for this. Perhaps the only real upside to insulating a non-insulated garage door is that you’ll be able to deaden some of the sound made when opening or closing the door.

Be Aware

If you use something other than the two materials we listed above, beware of adding any additional weight to the door. The springs on the door, as well as the opening system, are designed to handle a specific amount of weight. If you exceed this amount, it can cause serious damage. If you exceed the weight allowance, you’ll need to invest in new springs designed to handle the additional weight.

Should You Do It?

In the end, insulating a non-insulated garage door isn’t really worth it unless you really only wanted a little noise reduction. If you wanted to reduce heat and cold transfer in your garage, it’s a better option to buy a new garage door. This is particularly true if your old door is worse for the wear, and showing signs of its age.
