The garage door is the largest opening in your home. Insulated doors will help 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 or maybe run a small business out of your home, comfort will be a top priority. An insulated garage door will help keep the temperature in the garage more consistent as compared to the extreme range of outside temperature. This will allow you to be more productive because your garage will be much more tolerable.
  3. If you have a bedroom above your garage, air can travel through the ceiling of the garage into the room above. An insulated door will keep temperatures in the garage more stable which will help to reduce the temperature fluctuation in the room above. Many new homes have very little insulation in the ceiling of the garage so this could go a long way to helping you keep your cooling and heating bills lower.
  4. An insulated garage door is generally quieter and has a more attractive interior than a non-insulated door. For example, a steel back garage door like the one picture below will have a smooth metal interior finish which is pleasing to the eye and easy to keep clean.

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.

A door's insulating capabilities can be greatly affected by the door's construction. For that reason, Amarr's insulated doors are built to maximize energy efficiency. Our thermal break, door section construction and insulation help keep your garage as comfortable as possible.
