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.

Will insulating an interior wall help with noise?

Yes, noticeably for voices and television, even when sound was not the reason for the job. If a bedroom or office wall is open anyway, upgrading that cavity to a denser batt costs very little on top.

What about the pipes in my exterior wall?

Insulation goes behind them, between the pipe and the outside, not stuffed in around them. A water line on the cold side of the batt is a freeze risk in an Alberta winter, not just an efficiency question.

My room is cold and draughty. Will batts fix it?

Probably not on their own. Draughts around windows, an unsealed rim joist or gaps at the top plate are air leaks, and insulation does not stop air. We would rather diagnose the draught and quote the sealing, which is usually the cheaper half.

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.

Should batts be stapled tight to the studs?

The face-stapling shortcut dishes the middle of the batt and leaves a void behind it. A batt should sit by friction across its full width, touching framing on both sides and the sheathing behind.

Batt insulation in Decoteau before the vapour barrier goes on

Most of what separates good batt work from bad in Decoteau is invisible once the drywall is on. That is exactly why it is worth doing carefully: nobody can inspect it later without opening the wall, and the difference shows up as a cold room rather than as a visible defect.

Friction fit, not stapled tight

How a batt is meant to sit

An unfaced batt holds itself in an Decoteau bay by friction across its full width, touching the framing on both sides and the sheathing behind.

The common shortcut

Pulling a faced batt tight and stapling the flanges to the face of the stud, which dishes the middle and leaves a void behind. It looks tidy from the room and performs worse than it measures.

Cathedral ceilings and the ventilation gap

Do not fill it to the deck

In a vaulted Decoteau ceiling there has to be an air channel between the insulation and the roof sheathing. Packing batts tight to the deck closes it, and the roof has no way to dry.

What that costs later

Damp sheathing, mould and in the worst cases rot — none of it visible until it is expensive. The batt is sized so the channel stays open, which means accepting slightly less insulation depth in exchange for a roof that lasts.

Cutting to the bay, not the label

Real framing is not nominal

Decoteau walls, especially in older homes and renovations, carry bays that are wider or narrower than standard, plus cripples, blocking and services.

What we do

Measure and cut. A batt forced into a narrow bay is compressed and underperforms; one left short in a wide bay leaves a gap that convects. Both are invisible after boarding.

Compression is the most common Decoteau mistake

A squashed batt is a weaker batt

Batt insulation works because of the still air trapped in it. Compress it into a narrower bay and you lose a meaningful share of its performance while paying for the full product.

The fix is measurement

Decoteau framing is not always at a standard spacing, especially in older homes and renovations. We measure the bays and cut to fit rather than forcing a standard batt into a non-standard cavity.

Kneewalls and the rooms in the roof

A cold face nobody sees

A kneewall in an Decoteau storey-and-a-half has attic space directly behind it, so the back of that batt is exposed to outdoor air.

What it needs

The batt supported and its back face covered, rather than left open to the attic where air washes straight through it. Uncovered kneewall insulation is one of the most common finds in older homes.

Rim joists, the coldest part of a Decoteau basement

Small area, large loss

The rim joist is the band of framing where the floor meets the foundation. It is thin, it is directly exposed to outside, and in most Decoteau basements it is either bare or has a batt tucked loosely against it.

Air sealing first

A batt alone against a rim joist can trap moist air against a cold surface. The joint gets sealed first, then insulated, so warm household air is not reaching the cold band behind the insulation.
