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 St. Albert bays and cut to fit rather than forcing a standard batt in.

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.

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.

Do you insulate knee walls and attic hatches?

Yes, and they matter more than their size suggests. They are direct openings between heated and unheated space, and a well-insulated wall next to a bare knee wall performs like the weaker of the two.

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.

Do you cut batts to fit?

Yes. Real St. Albert 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.

Batt insulation in St. Albert, fitted rather than stuffed

Most of what separates good batt work from bad in St. Albert 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.

Insulating around plumbing on an exterior wall

Pipes belong on the warm side

A water line run in an St. Albert exterior wall cavity with the batt behind it is sitting on the cold side of the insulation. In February that is a freeze risk.

What we do

Wherever the plumbing allows, the insulation goes behind the pipe so the pipe stays in the heated space. Where it does not, we flag it rather than boarding over a line we know is exposed.

St. Albert drywall in context

About St. Albert

Albert has a genuine mix of older and newer homes (about 54% pre-1991, 25% since 2000), so we see both plaster and stipple repair and new-build basement development.

What we see in St. Albert

In St. Albert the drywall work is both plaster and stipple repair and new-build basement development. We confirm what your home actually needs on site, in writing, before anything starts.

Sound as a side effect of insulating

You get some for free

Filling an interior St. Albert wall cavity with batts noticeably reduces voice and television noise between rooms, even when sound was not the reason for the job.

Where to spend a little more

If a bedroom, office or bathroom wall is being opened anyway, upgrading that specific cavity to a denser acoustic or mineral wool batt costs very little on top of work already happening. We will point out which walls those are while we are quoting.

Compression is the most common St. Albert 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

St. Albert 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.

Batts around ducts and services

What is on the cold side

A duct or pipe run through an exterior St. Albert bay must have insulation behind it, between it and the outside, not merely stuffed in around it.

Consequence of getting it wrong

A water line on the cold side of the batt is a freeze risk in an Alberta winter, not just an efficiency question. It is worth the extra few minutes on each bay.

Kneewalls and the rooms in the roof

A cold face nobody sees

A kneewall in an St. Albert 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.

Vapour control, and why the order matters

Warm side, always

In St. Albert 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.
