Basement and rim-joist spray foam for Winnipeg foundations. Stop cold floors, drafts and moisture at the sill plate before you finish the basement.
Rim joists are a classic Winnipeg weak spot. Thin wood, lots of penetrations and direct exposure to outdoor temperatures. Closed-cell foam seals that band and basement walls so cold air is not pouring in at the foundation line.
Homeowners often notice warmer floors upstairs and fewer drafts after a rim-joist job. If you are finishing a basement, foaming first is one of the smartest steps before framing and drywall.
Walk across a Winnipeg basement in January and you will often feel it. Cold air pours in at the rim joist band where the floor framing sits on the foundation. That narrow strip of wood is full of penetrations for wiring, plumbing and ducts, and it is exposed to outdoor temperatures on the other side of the sill plate.
Fibreglass stuffed into rim bays rarely air-seals. Cold air still moves around the batt, and moisture can condense on cold wood. Closed-cell spray foam fills the bay, sticks to the foundation and joists, and creates a continuous seal along the perimeter of the house.
If you are framing a finished basement, foaming the rim and exterior walls first is one of the highest-value steps.
Closed-cell foam seals the band where the floor framing sits on the foundation, so cold air and drafts are not pouring into the basement and main floor.
Foaming exterior basement walls before studs and vapour details lock everything in gives you insulation and air sealing in one step.
On the River Heights Harris build in our portfolio we sprayed closed-cell foam at the main-floor rim joists, the band where the floor meets the exterior wall and cold air typically leaks in.
Closed-cell foam helps control moisture at the foundation line by stopping warm indoor air from condensing on cold wood and concrete at the sill plate.
New builds and additions may also need under-slab foam before the concrete pour, especially with radiant heat. That work has to be scheduled early, so talk to us while you are coordinating with your builder.
