The Advantages of an Insulated Garage Door

April 2, 2015

Insulation is an important part of any home, as it is impossible to be entirely comfortable in a space that lacks sufficient climate control. Of course, heating and cooling systems go a long way towards ensuring that the temperature in a room is comfortable, or at least livable, for you, but those systems can sometimes turn out to be a massive waste of money if you do not take the proper precautions vis-à-vis preventing the exterior temperature from influencing the interior temperature. Doing so can be rather difficult, especially in those rooms that are less-used and not as well connected to your heating and cooling systems, such as your garage. However, with the aid of garage door insulation, you should be able to maintain the temperature you want in your garage!

The Insulation Difference

The most sure-fire way to insulate your garage is with R17 garage door insulation. Basically, when it comes to garage door insulation, two materials are used: either polyurethane or polystyrene, two terms you’ve surely heard before. These two materials are very different in what they do and do not accomplish for you, insulation-wise, and knowing the difference will help you to make the best possible choice when it comes to your own home.

First, understand that the “R value” of a door indicates who well the insulation, well, insulates. A higher number following the R indicates a stronger level of insulation. To that end, R17 insulation is ideal if you want maximum insulation.

Polystyrene v. Polyurethane

Polystyrene tends to rate a lower R value, but is waterproof and easy to install in the sections that an overhead garage door would demand. Meanwhile, polyurethane is a denser material, and thus, its R values tend to be higher, reaching towards the heights of R17. If you are planning to actively heat or cool your garage with a heating or cooling system of some kind, it behooves you to use polyurethane, as it will more efficiently contain the temperature you want while keeping exterior temperatures from having a large effect on the interior temperature. Furthermore, polyurethane is great at soundproofing! What more could you ask for?
