Garage Door Insulation: What You Should Know 

You’ll hear a lot about garage door insulation when you’re shopping for a new door or evaluating the energy efficiency of your home. Since your garage is one of your main entry and exit points, it’s natural to find yourself concerned about the potential energy loss from this doorway. Also, if you use your garage for anything other than simply housing your vehicles, you probably wish it would retain heat a little better. 

Garage Door Insulation

What do you need to know about garage door insulation as a Utah homeowner who has to take cold, brutal winter temperatures into consideration?

R-Values: What They Mean

R-values tell prospective garage door buyers how energy-efficient their door is.

The R-value is any given materials’ ability to slow heat transmission. This means the higher the R-value, the more insulating the material will be. Typically, garage doors with higher R-values are more expensive as well as heavier, but they are better equipped to trap the heat in the garage and therefore avoid placing a strain on your home’s furnace.

Two Main Types of Insulation

There are two main categories of garage door insulation: polystyrene and polyurethane.

Polystyrene is like solid plastic foam and is placed within the garage door panels. Polyurethane is a spray foam. It is sprayed inside the garage door panels then bonds to each surface. For the most part, polyurethane provides higher R-values than polystyrene.

Many Factors Affect Warmth

Beyond a door’s R-value, many other factors affect the real outcome and the actual heat loss.

For example, when the garage door is installed, a comprehensive weatherproofing system should also be put in place. This product goes a long way in blocking air flow and heat loss, and it should be sturdy enough to withstand all types of precipitation.

The tightness of the door’s fit, the caulking and other installation factors also play a role in the energy efficiency of a garage door. Heat loss can be reduced with an experienced, knowledgeable install team handling the project.

Thorough Insulation Has Many Benefits

Besides the obvious — lowering your heating bills and keeping your garage warmer — high-quality garage-door insulation can provide other benefits as well. It can deaden noise, making your garage and your home quieter. It keeps your car in better condition since it’s not subjected to subzero temperatures in the dead of winter. Comprehensive insulation also reduces the number of tiny holes and cracks small rodents can use to slip inside your home during the winter, causing infestation problems.
