A cold floor over a crawl space in a Kamloops home usually traces back to an uninsulated rim joist and vented crawl walls. Closed-cell foam on the rim joist and the crawl walls turns the crawl space into a conditioned zone, stops the draft at the floor line and keeps pipes from freezing on the north-facing sides of Westsyde and Rayleigh homes.
A ground vapour barrier is laid first where the floor is dirt, and the crawl space vents are closed once the walls are foamed, per the current code approach for conditioned crawl spaces.
What is included
- Rim joists and sill plates, closed-cell foam
- Crawl space walls, with a ground vapour barrier
