Saving on energy bills is a common goal for many homeowners. One of the best ways to achieve this is by focusing on elements that help keep your home's heat or air conditioning inside. An energy-efficient door can play a significant role in reducing energy consumption, but not all doors can lower heating and cooling costs. The material used to make the door plays a crucial role in its efficiency. To maximize efficiency, choose a door with low thermal conductivity.
Having an energy-efficient door in your home offers many benefits. Apart from reducing heating and cooling bills, it can also make cold winter days more bearable, save time when the air conditioning is on, and much more!
The U-factor and R-value are two metrics used to measure the efficiency of a door. The U-factor or thermal resistance measures how well the door seals out air and maintains indoor temperature, while the R-value measures how well it insulates against heat loss. Higher U-factor and R-value values indicate better performance in keeping your home cool or warm in extreme weather conditions.
A door with an R-value of 13 is considered energy-efficient by most standards, but it may use more energy than some doors with lower R-values. A U-factor between 0.2 and 0.4 is ideal for optimal performance in cold weather, while a U-factor between 0.7 and 1 is recommended for maximum performance during hot weather conditions.
When shopping for a new door, look for one with an R-value of at least 11. The R-value is determined by dividing the thickness of the material used in inches by its density in pounds per cubic inch (psi). The lower the psi number, the more efficient your door will be. For instance, a 3/8" thick aluminum garage door with a density of 6.0 psi will have an R-value of 11. Investing in an energy-efficient door can result in significant energy savings and a more comfortable living environment.
