Do you cut batts to fit?

Yes. Real Mactaggart 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.

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.

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.

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

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.

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.

Batt insulation in Mactaggart, fitted rather than stuffed

A batt only performs if it fills the cavity completely and is not squashed. In Mactaggart 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
Batts friction-fit to full cavity width, not compressed
Mineral wool where fire or sound performance matters
Split and fitted around wiring and electrical boxes
Rim joists insulated and air-sealed
Odd bays cut to fit rather than packed

Wiring, boxes and the gaps behind them

Where the cold gets in

The fastest way to ruin a wall in Mactaggart 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.

Mactaggart drywall in context

About Mactaggart

The MacTaggart neighbourhood takes its name from Sandy Auld Mactaggart, a local entrepreneur and philanthropist with provincial, national and international achievements in business, the arts, and education.

What we see in Mactaggart

In Mactaggart the drywall work is first-year settling, basement dev for first owners, Level 5 over builder-grade. We confirm what your home actually needs on site, in writing, before anything starts.

Vapour control, and why the order matters

Warm side, always

In Mactaggart 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 Mactaggart 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.

Batts around ducts and services

What is on the cold side

A duct or pipe run through an exterior Mactaggart 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.

Sound as a side effect of insulating

You get some for free

Filling an interior Mactaggart 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.

Kneewalls and the rooms in the roof

A cold face nobody sees

A kneewall in an Mactaggart 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.
