Garage Attic Insulation

Garage attic insulation, also known as garage radiant barrier is a type of reflective insulation that blocks sunlight from penetrating into the roof of your garage and heating it up. Installing garage attic insulation along with garage door insulation will help keep garage temperatures stable. However, the only way to experience true comfort in your garage is to install a garage mini split heating and cooling unit. This way you can keep your garage whatever temperature you would like. For those looking to use their garage as a workshop, a garage ac unit can be priceless!

Insulating the garage attic, if you have one, is needed for cooling as well. You can’t insulate your garage without insulating the attic first. The hotter the attic is in your garage, the hotter your garage will be no matter what type of insulation or cooling mechanism you’ve installed.

Your garage’s attic is where most of the heat comes into your garage during warmer months of the year like July and August.

If you live in Sunny states like Arizona, Texas and Florida, insulating a garage attic is a must if you want to keep your garage cool enough to withstand for short periods of time.

However, if you plan on spending any real time in your garage, meaning hours or more, you are going to need a lot more than garage attic insulation to make the temperature manageable enough to withstand for long periods of time.

If you are planning on turning your garage into a workshop, your next step should be to insulate your garage door.

You should use garage attic insulation if:

• Your HVAC unit extends into your garage
• You have an air-conditioned room above your garage
• You’re turning the garage into a bedroom
• You’re planning on keeping pets in the garage
• You’re planning on turning your garage into a studio, man-cave or workshop

Installing garage attic insulation will cost you about $500 for a one car garage and about $800 for a two car garage. In general, it costs about $2 per sqft to install garage attic insulation.
