Garage Insulation in Manhattan, KS
A garage is easy to overlook, but an uninsulated one doesn't just make the garage itself uncomfortable — on an attached garage, it can pull heat straight out of the room next to it. We spray foam garage walls and ceilings across the Flint Hills, whether you're converting the space into a workshop or just tired of a cold shared wall.
Why Garages Get Overlooked — and Why That's a Mistake
Garages are often the least finished part of a house, and it shows — bare studs, no insulation, and a garage door that's rarely airtight. On a detached garage or shop, that mostly just means the space itself is uncomfortable. On an attached garage, it's a different story: the wall shared between the garage and the house is a direct thermal connection to living space, and an uninsulated garage can pull heat out of the room next to it far more than most homeowners realize.
Spray foam fills the wall and ceiling cavities completely, sealing air movement in the same step, which matters whether you're trying to protect the room next door or just make the garage itself usable for more than parking a car.
The Fire-Rated Wall Requirement
Spray foam doesn't replace the fire-rated wall. Most building codes require a fire-rated wall assembly — typically 5/8-inch Type X drywall — between an attached garage and living space, since a garage is treated as a higher fire-risk area. Spray foam adds real thermal performance to that wall, but it's not a substitute for the fire-rated drywall itself. If your garage's shared wall doesn't currently meet that requirement, that's worth addressing alongside any insulation work, not instead of it.
Why People Insulate Their Garage
Converting to a Workshop
Turning the garage into a space you'll actually spend time in, year-round, not just park a car.
Protecting the Shared Wall
Stopping an uninsulated garage from pulling heat out of the room next to it.
Protecting Stored Items
Keeping temperature-sensitive tools, supplies, or a second refrigerator out of extreme swings.
Noise Control
