Do you cut batts to fit?

Yes. Real Riverdale 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.

What about the wiring in the wall?

The batt gets split so part sits behind the cable and part in front, and it is cut around boxes. Stuffing it behind the wiring leaves an uninsulated void right where there is already a hole in the vapour barrier.

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.

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.

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.

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.

Batt insulation in Riverdale before the vapour barrier goes on

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

Insulating around plumbing on an exterior wall

Pipes belong on the warm side

A water line run in an Riverdale 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.

Riverdale drywall in context

About Riverdale

Just east of City Hall and bounded to the south and east by the river, this large flat area is an important part of Edmonton's history.

What we see in Riverdale

In Riverdale the drywall work is infill new-build settling beside original-stock plaster/popcorn work. 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 Riverdale 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.

Wiring, boxes and the gaps behind them

Where the cold gets in

The fastest way to ruin a wall in Riverdale 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.

Batts around ducts and services

What is on the cold side

A duct or pipe run through an exterior Riverdale 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.

Vapour control, and why the order matters

Warm side, always

In Riverdale 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.

Attic hatches, knee walls and the bits at the edges

Small areas, outsized effect

Knee walls in a Riverdale storey-and-a-half, the back of an attic hatch and the ends of joist bays are commonly left bare because they are awkward.

Why we do them anyway

They are direct openings between heated and unheated space. A wall insulated to a high standard with an uninsulated knee wall beside it performs like the weaker of the two, and those edges are where cold rooms usually trace back to.
