Attached garages and the room above
Bonus rooms over garages are the coldest space in thousands of Minnesota homes because the floor cavity is open to outside air at the perimeter and the batts fell out years ago. Foaming the garage ceiling seals that cavity and finally makes the room upstairs livable.
Foam at the shared wall also blocks exhaust fumes, solvents and other garage air from being pulled into the house, which is a genuine indoor air quality upgrade.

Heated detached garages
For a detached garage you plan to heat, foam on the walls and roof deck lets a small heater hold temperature economically instead of running nonstop. Overhead door framing, headers and the top plate get sealed as part of the job.
Most single- and double-stall garages are completed in one day.
Frequently asked questions
- Will foaming the garage ceiling fix my cold bonus room?
- In almost every case it is the single most effective fix, because the real problem is outside air moving through the floor cavity.
- Does exposed garage foam need to be covered?
- Code generally requires an ignition barrier over exposed foam in a garage. We explain the options and include them in the estimate.
