Batt Insulation Bonnie Doon Edmonton

Batt insulation in Bonnie Doon, fitted rather than stuffed

A batt only performs if it fills the cavity completely and is not squashed. In Bonnie Doon 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.

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

Batt Insulation Bonnie Doon Edmonton: your questions answered

Why is my Bonnie Doon 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 the garage wall need anything special?

Usually yes — a fire separation as well as insulation, planned together because the board is specified. Insulation and vapour control go in and get inspected, then the rated board goes on.

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 Bonnie Doon bays and cut to fit rather than forcing a standard batt in.

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.

Do you cut batts to fit?

Yes. Real Bonnie Doon 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.

Do you install the vapour barrier as well?

Yes, and the order matters. Insulation is completed first, the barrier goes on the warm side and is sealed at penetrations before boarding. None of it can be corrected once the drywall is up.
