About Spray Foam for Garage Attics

An insulated garage attic insulation home comfort while protecting stored items and reducing energy costs. While upfront costs are higher than fiberglass or cellulose insulation, long-term energy savings make the upgrade well worth it.

Garage walls require R13-R21, while ceilings and rafters require R30-R40. The R-value depends on the area of the garage and target temperature. Closed-cell spray foam reaches these levels with less thickness than fiberglass and cellulose, lowering installation time and cost. It also resists moisture and mold, preserving the integrity of your home.

Spray foam insulation can be installed in a finished or unfinished garage, but an insulated ceiling is most common. To install the insulation, a professional drills small access holes into wall studs and injects foam in each hole. This process is faster than removing and replacing drywall, and it doesn’t affect the strength of the studs or structure.

Using Spray Foam in Older Buildings: What to Consider

Insulating an existing finished garage may be less expensive. If the existing drywall is in good condition, installers simply reinstall it. They may use a different technique, however, to ensure that the insulation is properly secured.

Builders often skip insulating the ceiling between a garage and living space above. This is because drywall acts as an air barrier, but it doesn’t seal gaps and voids. Insulating the ceiling with spray foam solves this problem, providing a complete air and thermal seal. It also keeps a consistent R-value and withstands Wisconsin’s weather conditions.
