Can the rafter bays be filled right up?

Not in a vented cathedral ceiling. A clear air channel has to stay between insulation and roof sheathing, held open with baffles, or the deck cannot stay cold and dry.

Why is my Woodcroft basement cold along the floor edge?

Usually the rim joist. It is thin, directly exposed to outside, and in most basements it is bare or has a batt tucked loosely against it. It needs air sealing first, then insulating.

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.

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.

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

Can batts go straight against my Woodcroft basement concrete?

No. Against bare concrete they sit on the cold side where moisture cannot dry, and that is the usual reason a finished basement smells musty a year later. The framing is held off, or a rigid layer goes on first, so the batts stay on the warm side.

Batt insulation in Woodcroft, fitted rather than stuffed

Most of what separates good batt work from bad in Woodcroft 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.

Kneewalls and the rooms in the roof

A cold face nobody sees

A kneewall in an Woodcroft 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.

Woodcroft drywall in context

About Woodcroft

Woodcroft contains Westmount Shopping Centre, a shopping centre built in 1955 which was the first of its kind built in Edmonton.

What we see in Woodcroft

In Woodcroft 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.

Mineral wool against fibreglass in Woodcroft

Different tools

Fibreglass batts are the common choice and perform well when fitted properly. Mineral wool is denser, holds its shape better in a cavity, handles fire differently and performs noticeably better for sound.

Where we would spend the difference

Party walls, bedrooms, mechanical rooms and any assembly where sound or fire matters. For an ordinary interior partition in Woodcroft, fibreglass fitted well beats mineral wool fitted badly.

Wiring, boxes and the gaps behind them

Where the cold gets in

The fastest way to ruin a wall in Woodcroft 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.

Insulating a Woodcroft basement wall against concrete

Not the same as a framed wall above grade

A basement wall in Woodcroft is concrete, cold, and can carry moisture from the ground. Batts pressed straight against bare concrete sit in exactly the wrong place: the cold side, where any moisture they pick up cannot dry.

How the assembly works

The framing is held off the concrete, or a rigid layer goes against the wall first, so the batts sit in a cavity that stays on the warm side. Getting that order wrong is the usual reason a finished Woodcroft basement smells musty a year later.

Rim joists, the coldest part of a Woodcroft 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 Woodcroft 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.

Cathedral ceilings and the ventilation gap

Do not fill it to the deck

In a vaulted Woodcroft 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.
