We were speaking with a customer the other day who shared her desire for insulated garage doors because her master closet is directly above the garage and her clothes were very cold in the morning. During a new garage door consultation at her home, we discovered that she had two non-insulated garage doors. This means her garage doors were built from only steel sections. Without a layer of insulation or backing, her doors were not regulating the temperature of her garage, allowing the cold to seep into the closet above. However, with a set of high quality insulated garage doors on her home, the energy efficiency and noise control of her garage improved dramatically.
The most common measure of energy efficiency for garage doors is R-value. R-value is a numeric applied to doors based on how much they slow the transmission of heat. The higher the R-value, the slower the transmission of heat through the insulation. This means your garage stays at a more comfortable temperature even on the worst days of summer and winter. To put it in perspective, a non-insulated door has an R-value of 0, providing little to no energy efficiency for your home. However, an insulated garage door can provide up to 19 R-Value. This means you get higher levels of energy efficiency, noise control, and temperature moderating for your home.
Insulated Garage Doors
If you decide to invest in an insulated garage door, there are two options. The first is a two-layer insulated door. These doors feature steel sections with exposed polystyrene on the interior. This means you can see the insulation when inside your garage, even poke holes in it. For this reason, we don’t typically recommend a two-layer insulated garage door. Also, this door variety doesn’t offer as much energy efficiency and noise control as a three-layer insulated garage door.
The best option you can choose for garage door insulation is a three-layer insulated door. This is commonly known as a sandwich door. It has steel on the front and back with insulation in the middle. This insulation can be either blocks of polystyrene or a foam compound that hardens inside the door frame called polyurethane. Either of these provide the insulation you need to protect your garage, but polyurethane is suggested for the best energy efficiency. If you want to upgrade your garage with insulation, a sandwich door is your best bet, especially with polyurethane. Although it is more of an investment, you can’t beat the long term benefits.
Other Energy Efficiency Suggestions
Looking for another way you can prevent cold air from entering your garage? Replace your weather stripping along the bottom of the door. Weatherstripping adjusts the door so it is flush to the ground and seals the gaps around the top and sides of the closed door. However, over time the weather stripping wears out and creates gaps. As these gaps grow, cold or hot air can enter your garage, making it more uncomfortable. But if you replace your weatherstripping regularly, less hot or cold air will enter your garage, creating better temperature regulation.
