Spray Foam Insulation King city | Insulation Contractor
King city winters drive stack-effect air leaks through rim joists, garages, and rooms over garages. We install closed-cell foam (≈R-6–R-7 per inch) where moisture and structural rigidity matter, and open-cell foam where sound control and value are the priority. All installs follow Ontario Building Code requirements for ignition barriers and ventilation.
Why Spray Foam Works Best in King City
King City’s mix of newer estate homes and older farmhouses sees big stack-effect losses in winter and humidity in summer. Closed-cell foam stops air and vapour at the shell; open-cell adds acoustic comfort and value inside. Here’s where spray foam outperforms other options in King City builds:
Ice/condensation control over living space
Closed-cell foam creates a continuous air & vapour barrier in garage ceilings or bonus rooms to prevent frost and dripping.
Rim-joist air sealing to stop drafts
Spray foam seals rim bays where most houses leak, cutting cold floors and stack-effect drafts.
Basement thermal break to dry up cold walls
Closed-cell foam adds R-value and moisture control on foundation walls for warmer, drier basements.
Shops, barns & outbuildings in King Township
Spray foam slashes heat loss and air leakage in metal or pole-barn structures along the Hwy 400 corridor.

What King City Homeowners Say
Real feedback from recent spray foam projects around King Township.
GTA Foaming sealed our rim joists with closed-cell and the difference was immediate—no more cold floors or drafts. Crew was quick and left everything spotless.
Had our vaulted ceiling sprayed with 5.5" closed-cell. No ice-dams last winter and the upstairs is finally even in temperature. Professional from quote to cleanup.
We insulated a metal workshop with 3" closed-cell. Noticeable drop in heating costs and way less dust coming in. Great advice on thickness and code.
