Most garages around Sapulpa were built with little or no insulation. That is fine for parking a car, but it causes real problems in two situations. An attached garage that shares a wall or ceiling with living space pulls heat out of the house in winter and pushes heat in all summer, which is why the bedroom over the garage is so often the hottest room in the house. A detached garage or workshop that you actually spend time in becomes unusable from June through August and miserable in January.
Garage spray foam insulation seals and insulates the walls and ceiling in one step. Foam fills every gap around the framing and the rim, stops drafts and dust, and slows the heat flow that makes the space follow the outdoor temperature. Closed-cell foam also resists moisture and adds rigidity, which helps in older detached garages and shops with metal siding.
Every garage project starts with a free estimate. We look at which walls are shared with the house, what is above the ceiling, how the garage door and openings are sealed, and whether the walls are open or finished.
TipFoam the ceiling under a bonus room first. If there is a room over your garage, the garage ceiling and the floor of that room usually matter more than the garage walls for comfort upstairs.
Signs You Need Garage Spray Foam Insulation
- The room over the garage is always hotter or colder than the rest of the house
- The garage is too hot or cold to work in
- Drafts and dust come in around the walls and rim
- You plan to add a mini-split or heater to the garage
- Condensation forms on a metal garage or shop roof
- You are converting the garage into a gym, office or living space
Insulating Garage Walls, Ceilings and Doors
Open garage walls and ceilings can take open-cell foam at about 3.5 inches in 2x4 framing for roughly R-13, a cost-effective choice for attached garages. Closed-cell foam at about 2 inches gives similar R-value plus moisture resistance and strength, and it is the better fit for detached shops, metal garages and garages that see a lot of humidity.
Garage doors are usually handled with an insulated door or a door insulation kit rather than spray foam, plus good weatherstripping. Fire safety matters too: foam in a garage generally needs to be covered by drywall or an approved thermal barrier coating, and the wall between an attached garage and the house has its own fire separation rules. We plan the foam so it fits those requirements.
