Batt Insulation Cavanagh Edmonton

Batt insulation in Cavanagh before the vapour barrier goes on

A batt only performs if it fills the cavity completely and is not squashed. In Cavanagh the two things that ruin it are compression — jamming a wider batt into a narrow bay — and gaps around wiring and boxes, where the insulation is stuffed behind rather than split around.

• Vapour control detailed before the board goes on
• Split and fitted around wiring and electrical boxes
• Rim joists insulated and air-sealed
• Mineral wool where fire or sound performance matters
• Odd bays cut to fit rather than packed
• Batts friction-fit to full cavity width, not compressed

Batt Insulation Cavanagh Edmonton: your questions answered

Can you insulate my finished walls without removing the drywall?

Not with batts — they need an open cavity. That is a job for a blown-in or injected product, or for adding insulation on the room side. We will tell you that rather than sell you a partial job.

Why is my Cavanagh basement cold along the floor edge?

Usually the rim joist. It is thin, directly exposed to outside, and in most basements it is bare or has a batt tucked loosely against it. It needs air sealing first, then insulating.

Does it matter if the batt is squashed in a bit?

Yes, more than most people expect. Batts work through trapped still air, so compressing one into a narrow bay costs a real share of its performance. We measure the Cavanagh bays and cut to fit rather than forcing a standard batt in.

Do you cut batts to fit?

Yes. Real Cavanagh framing carries bays wider or narrower than nominal, plus cripples and blocking. Forced batts are compressed and underperform; short ones leave gaps that convect. Both are invisible after boarding.

Faced or unfaced batts?

One system per wall. Faced batts carry their own vapour retarder; unfaced are paired with a separate poly barrier. Using both in one assembly can trap moisture between two retarders.

There is a water pipe in my exterior wall. What happens to it?

Wherever the plumbing allows, the insulation goes behind the pipe so the pipe stays on the heated side. If it cannot, we flag it rather than boarding over a line we know is exposed to freezing.
