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.

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.

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.

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.

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.

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.

Batt insulation in Dovercourt, fitted rather than stuffed

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

What batts will not fix

Insulation is not air sealing

If a Dovercourt room is cold because of draughts around windows, an unsealed rim joist or gaps at the top plate, filling the cavity with batts will disappoint you.

Why we say it first

We would rather diagnose the draught and quote the sealing than sell you insulation that does not solve the complaint. The two jobs go together, and the sealing is usually the cheaper half.

Dovercourt drywall in context

About Dovercourt

Dovercourt and surrounding area was annexed to Edmonton in 1913 but remained practically undeveloped until after the Second World War.

What we see in Dovercourt

In Dovercourt the drywall work is plaster and lath repair, popcorn and stipple ceiling removal, careful patching into original surfaces. We confirm what your home actually needs on site, in writing, before anything starts.

Friction fit, not stapled tight

How a batt is meant to sit

An unfaced batt holds itself in an Dovercourt 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.

Vapour control, and why the order matters

Warm side, always

In Dovercourt the vapour barrier goes on the warm side of the insulation. Putting it in the wrong place, or having two of them, traps moisture inside the assembly where it cannot dry.

Sequencing

Insulation is completed and inspected before the barrier goes on, and the barrier is sealed at penetrations before boarding. Once drywall is up, none of this can be corrected without taking the wall apart again.

Cathedral ceilings and the ventilation gap

Do not fill it to the deck

In a vaulted Dovercourt 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.

Rim joists, the coldest part of a Dovercourt 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 Dovercourt 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.

Wiring, boxes and the gaps behind them

Where the cold gets in

The fastest way to ruin a wall in Dovercourt is to stuff the batt behind the wiring and the electrical boxes. It leaves an uninsulated void exactly where there is already a hole in the vapour barrier.

Split, do not stuff

The batt is split so half sits behind the cable and half in front, and it is cut around boxes rather than compressed past them. It is slower and it is the difference between a wall that performs and one that only looks insulated.
