The Importance of Insulated Garage Doors

You wouldn’t leave your walls or front door uninsulated, so why would you not insulate the largest opening to your home?! If your garage is attached to your home, air can travel through the doorway to your living area.

Insulated doors will help to reduce the transfer of heat or cold air into your garage while saving you money on your electric bill. (just don’t spend all of the savings in one place!)

The Garage Craftsman

If you use your garage as a workshop, you don’t want to be shivering from the cold as you meticulously use the bandsaw. 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. (so count your fingers safe.)

The “Bonus” Room

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, making an awesome sauna or icebox. An insulated garage door will keep temperatures in the garage fairly stable to reduce the temperature fluctuation in the room above.

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. Got all that?

The higher the R-value number, the better the insulated your garage will be. Here is where it gets tricky, an R-16 value is not twice as good as an R-8 Value. The chart below does a great job at detailing this out.

As always, if you have questions about R-value, or anything, contact us at any time! We are happy to answer your questions.
