Do I really need an insulated garage door?

Does it make sense to insulate an unheated garage?

Engineering studies have shown that replacing a non-insulated garage door with an insulated one can reduce heat loss through the garage by more than 70%. Even if your garage is unheated that could mean a garage that’s warmer by as much as 20 degrees Fahrenheit on the coldest Colorado nights.

Does a detached garage need an insulated garage door?

There are cases where an insulated garage door is not needed, like if you have a detached garage that simply stores your vehicle or tools. If your space doesn’t require you to spend any length of time in it, it may make more sense financially to use a non-insulated door.

How important is R value for garage doors?

A garage door’s R-value represents its ability to slow the transmission of heat. A higher R-value means a slower transmission of heat, which means less cold air leaking into your garage in the winter and less heat invading your garage in the summer. When it comes to R-values for garage doors, the higher the better!

How can I insulate my garage cheaply?

Fiberglass roll insulation is the cheapest and easiest type to install, provided that your garage’s interior walls have not been constructed. Unroll the insulation between the wall studs with the vapor barrier facing the inside of the garage.

Will insulating my garage keep it warmer?

Garage Door Insulation Kits: The Best Way to Keep Your Garage Warm in the Winter and Cool in the Summer. While adding space heaters in the winter or portable fans in the summer can help regulate how warm or cool your garage is, insulation is ultimately the best way to keep your garage cool in summer and warm in winter.

What is the R-value of an insulated garage door?

Attached but not actively heated or cooled garages should have a garage door with an R-value between R-6 and R-9. Actively cooled or heated garages should have a garage door with an R-value of R-13 or higher to save on energy costs. In general, a higher R-value means better insulation, but there’s more to it than that.

How cold does a detached garage get?

In winter, even when it’s freezing outside, a well insulated garage will generally stay around 20 – 30 degrees. Metal tools will still be cold but it’s not uncomfortable to work in. And insulation helps prevent drafts.
