Garage Spray Foam Insulation in Mississauga
Sealing the gap between the garage and the rest of the house
Attached garages are a common source of drafts, temperature swings, and, in some cases, exhaust or fume infiltration into living space above or beside them. The shared wall or ceiling between a garage and the house is often under-insulated compared to the rest of the exterior envelope, since it’s easy to overlook during original construction. Explore our residential spray foam insulation services for related applications and service areas.
Spray foam insulates and air seals this shared boundary in one step, which matters more here than in a typical exterior wall, since the goal is both thermal separation and sealing the garage off from the living space.
Attached versus detached garages
Attached garages are usually insulated primarily to protect the adjacent living space: the shared wall, the ceiling below a bonus room, and the door between the garage and the house. Detached garages are insulated more like a small standalone building, and the scope depends on whether the space is meant to be heated, used as a workshop, or just better protected from temperature swings.
What gets insulated
- The shared wall between an attached garage and the house
- The ceiling below a room located above the garage
- Garage doors and door surrounds, where air sealing is often weakest
- Detached garage walls and roofline, for spaces used as workshops or heated storage

Frequently Asked Questions
Often yes, if it shares a wall or ceiling with living space, since the goal is protecting the house rather than heating the garage itself.
Air sealing the shared wall and ceiling reduces air movement between the two spaces, which can reduce fume infiltration, though a working exhaust fan and a sealed door are also part of addressing this properly.
The approach is similar, but the scope depends on whether the detached garage will be heated or used as a workshop, which affects how much of the structure needs insulating.
