3 Things You Should Know About Garage Door Insulation

3 Things You Should Know About Garage Door Insulation

Is your home insulated? Of course it is and you probably have an idea of the type of insulation and it’s R-value

In your garage door insulated? Chances are that you don’t know the answer. So you wouldn’t know the type or R-value of the insulation either, and you probably don’t care.

But you should. An insulated garage door offers many of the same benefits as your home’s regular insulation, and a few more.

First, R-value is the measure of how well any insulation prevents the transit of heat from one side of the insulation to the other. The higher the R-value, the better the insulation.

There are lots of reasons for you to pay more attention to your garage door’s insulation and it’s R-value.

1. It Saves You Money

Just like your regular home insulation, the stuff in your garage door prevents heat from getting out in the winter and prevents it from getting in during the summer. It doesn’t matter that you don’t heat or air condition you garage. The heated and cooled air from your home gets into your garage. Without an insulated door, that expensively heated or cooled air is lost much faster.

2. It Protects Your Belongings

Many of the things you keep in your garage, like a lawn mower, can suffer from exposure to freezing temperatures. But even worse than temperature extremes, the fluctuation from cool to warm temperatures, like in the spring and fall when nights can be quite cool, but the days much warmer, can be even worse. That relatively quick shift from cool to warm can cause condensation on the objects in your garage. Condensation that could cause metal objects, again like your lawn mower, to rust or mold to grow just about anywhere.

3. You May not Have the R-value You Think

The two main types of garage door insulation are polystyrene foam and polyurethane foam. Polystyrene comes in sheets (you might call it Styrofoam) and, even when it is well fitted to your garage door panels, it can’t get into every space and crack, leaving areas that might be almost fully exposed to outside air. Polyurethane foam is sprayed on and it expands to fill every gap.

But no matter which type of insulation you have, if the gaps between the door panels and around the outside of the door aren’t properly sealed, then air can get out and in with nothing in its way. That means you could have a certain R-value for your insulation, but that wouldn’t be the effective R-value of the overall door.

From making it easier for your car to start in winter, to reducing the noise in your garage all the time, there are many other benefits to an insulated garage door. So the next time you look at your door, or are in the market for a new one, make sure it’s well insulated and well-sealed.
