A third of the air.

Roughly 33% of the conditioned air you paid for leaves through holes, cracks and seams in the envelope.

Fill vs seal.

Fiberglass fills cavities. It does not seal them. Air still moves. Spray foam adheres and closes the envelope.

[03]

Closed cell, R-6.

2 lb closed cell is about R-6 an inch — air barrier, moisture control, vapour retarder, and a bit of structure.

[04]

Tight, then vent.

Make it tight and ventilate right. About 90% of moisture problems start with air movement — mould, rot, the usual.

Where it goes.

Closed cell only, unless a spec says otherwise. Open cell has not got the vapour resistance for a Manitoba winter.

The envelope

Spray polyurethane foam seals holes, cracks and seams so indoor air stays in and outdoor air stays out — including the hard-to-reach interfaces that leak energy.

Walls, floors, ceilings

New builds and renovations. Foam fully adheres to almost any surface. We spray the cavities, the rim, the underside — wherever the envelope actually is.

Basements, rims, crawls

Basements, rim joists and crawlspaces are where a lot of that 33% leaves. Closed cell here cuts air leakage and the moisture that rides with it.
