When looking for a new garage door, you will want to make sure that it is energy efficient. Energy efficiency levels can help you save a lot of money in heating costs in the long run and help the climate. Proper insulation is essential in this case, but not all insulation is created equal. Thankfully, there is an indicator that can measure how energy efficient garage doors are.
What Is the R-Value?
The R-value measures the thermal resistance (=R) of a two-dimensional barrier against the flow of heat. In other words: how well does your door or window keep heat in or out? The higher your R-value, the better insulated your door or window is.
The value is based on the thickness of your installed insulation. Be sure to look for garage doors with a higher R-value.
Other Factors Influencing R-Value
Of course, your garage door’s insulation plays a big role in determining the R-value. However, the door’s construction also plays a role. A garage door without windows, for example, is more energy-efficient since it requires less insulation. However, you also want your garage door to fit your home’s overall presentation and style.
Therefore, make sure that the garage door of your choice is constructed to maximize its energy efficiency levels. The better your garage door is constructed, the more efficient the insulation will be. The more efficient the insulation, the higher your garage door’s R-value and overall energy efficiency level will be.
Make sure to check the R-value of your current garage door. If it is not sufficient, you may want to contact a professional to help you insulate it properly or replace it with a more energy efficient garage door.
