Insulating parking structures protects the structure from outside elements while creating an airtight seal to the livable space. Closed cell spray foam on structure ceilings is being embraced by multi-family property builders and property managers as a smarter investment. Call SprayTight — get it done right!
Comfort Above, Protection Below
When apartments, condos, or offices sit above a parking deck, every degree of winter cold radiates straight up through the slab into the space above. Cold floors, overworked furnaces, and complaints from tenants are the result. Applying closed cell spray foam to the parking structure ceiling puts a seamless thermal and air barrier between the garage and the conditioned space above it.
Closed cell foam adheres 100% to concrete and steel decks, fills every gap around beams, pipes, and penetrations, and resists the moisture and temperature swings a Michigan parking structure sees all year. It is the same proven approach we use on basements & crawl spaces and apartment & condo projects across the state.

Why Builders & Property Managers Choose Spray Foam
Airtight Seal to Living Space
Foam seals the deck ceiling and every penetration, stopping cold air, fumes, and moisture from migrating into the occupied floors above.
Element Protection
A monolithic closed cell layer shields the structure itself from outside elements, moisture, and freeze-thaw stress.
A Smarter Investment
Multi-family builders and property managers are embracing spray foam because it lowers energy costs and tenant complaints in one application.

Frequently Asked Questions
Why insulate a parking structure with spray foam?
Insulating parking structures protects the structure from outside elements while creating an airtight seal to the livable space above or beside it. Residents stay comfortable, floors above the deck stay warm, and the building's mechanical systems work less.
Who typically orders parking structure insulation?
Closed cell spray foam on parking structure ceilings is being embraced by multi-family property builders and property managers as a smarter investment for condos, apartments, and mixed-use buildings.
Where is the foam applied in a parking garage?
The most common application is the parking deck ceiling — the underside of the floor separating the garage from conditioned living or working space — along with rim areas and penetrations that leak air between the garage and the building.
Does spray foam meet the demands of a parking environment?
Yes. Closed cell foam is rigid, moisture-resistant, and adheres fully to concrete and steel, making it well suited to the temperature swings, humidity, and exhaust exposure of an open or enclosed parking structure.
