In any home, an R value will tell you how well something insulates. There are “guns” that you can get which measure the R value in your home, showing what areas of your home are well-insulated, and which ones are not. The higher the R value is, the better your home insulates.

If your home is not well-insulated, you may lose a great deal of heat, which can cost you anywhere from hundreds to thousands of dollars every year. If you’re someone who uses your garage a great deal, especially if you use it to do wood working or fixing machines, you will want to ensure that your door is very well insulated.

Many homes have a garage underneath the top floor, and normally this is not a problem. If you have a garage door that has a low R value to it, however, you may find that the room directly over the door is extremely cold, even if you have it carpeted. This is because heat is escaping from the garage door and cold is getting in, which is almost impossible to combat. In order to ensure that the room above a garage door stays warm, it is vital that you have good insulation, and a door that has a good R value.

What type of numbers should you look for when it comes to the R value on a garage door? The rule of thumb is the higher, the better. If you find a door, for instance, that is thick, the R value might be as high as 6.5. If, however, you find a lower priced door that is made with inexpensive materials, the R value might be something like 4.3. While the numbers may not seem that different, they are. With a door R value of 4.3, you would be letting a great deal of cold into your garage. When you’re shopping for a garage door, look for one that has a high R value so that you can keep your garage well-insulated.
