Home Addition Spray Foam Insulation In Doon, Ontario

Additions Lose Heat Faster Than The Rest Of The House

An addition usually has three outside walls, a new roof and a new floor. That leaves far more surface open to the cold than a room in the middle of the house. Addition spray foam insulation seals the seams between new framing and old, which is where drafts usually begin.

Spraying Right After Framing

The best moment for addition spray foam insulation is after the framing, wiring and plumbing are in and before the insulation inspection. We line up with your contractor so the foam goes in on schedule and the drywall can follow.

Closed cell foam in exterior walls adds stiffness and controls vapour. Open cell can go in interior walls to soften sound between rooms.

Four-Season Sunrooms Need Insulated Walls And Roofs

A sunroom is mostly glass, so every other surface has to pull extra weight, and addition spray foam insulation is how those surfaces keep up. We insulate the knee walls, the roof and the floor so the room stays usable in winter. Addition spray foam insulation also keeps the room cooler on summer afternoons.

Meeting Code For A New Addition

New additions in Ontario must meet current energy rules, which call for roughly R-24 in above-grade walls. Foam reaches that level in a thinner wall than batts can. The building department decides what your project needs, and we hand your builder the product details they request.
