Why You Need An Insulated Garage Door


garage door covers the largest opening in your home, an insulated door will help to reduce the transfer of heat or cold air into your garage. This is important for a number of reasons:

(1) If your garage is attached to your home, air in the garage can travel through the doorway to your living area. An insulated garage door will reduce the transfer of air from the outside to the inside.

(2) If you use your garage as a workshop, your comfort will be a top priority.  An insulated garage door will help keep the temperature in the garage within a narrower temperature range as compared to the extreme range of the outside temperature.

(3) If your garage is below another room in your home, air can travel through the ceiling of the garage into the floor of the room above. An insulated door will keep temperatures in the garage fairly stable to reduce the temperature fluctuation in the room above.

(4) An insulated garage door is generally quieter and has a more attractive interior than a non-insulated door.


What is R-Value?

R-Value is a measure of thermal resistance used in the building and construction industry. Specifically, R-value is thermal resistance to heat flow. Many manufacturers use R-values to show the energy efficiency of their product. This number is calculated based on the thickness of the insulation and its chemical properties. The higher the R-value number, the better the insulating properties of the material.

Bestar Model 5000 Series Garage Doors, with R Value 17.10, manufactured with 3 layer construction (steel+insulation+steel), provide exceptional strength, energy efficiency, rust resistance and noise reduction. The 2” thickness of polyurethane insulation and thermal break rubber makes those doors heat and cold resistant, while the tongue-and-groove joint helps seal out wind, rain and snow.
