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 Westmount 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.

Should I use mineral wool or fibreglass?

Fibreglass fitted well beats mineral wool fitted badly for an ordinary partition. Mineral wool is worth the difference on party walls, bedrooms and anywhere sound or fire performance matters — it is denser and holds its shape in the cavity.

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.

Can batts go straight against my Westmount 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.

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.

Batt insulation in Westmount before the vapour barrier goes on

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

Batts friction-fit to full cavity width, not compressed
Rim joists insulated and air-sealed
Mineral wool where fire or sound performance matters
Vapour control detailed before the board goes on
Odd bays cut to fit rather than packed
Split and fitted around wiring and electrical boxes

Cathedral ceilings and the ventilation gap

Do not fill it to the deck

In a vaulted Westmount 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.

Westmount drywall in context

About Westmount

Westmount likely takes its name from an affluent, predominantly Anglophone, city on the west island of Montreal.

What we see in Westmount

In Westmount 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.

Handling, dust and leaving it clean

Practical realities

Batt work makes airborne fibre and it settles everywhere if the space is not controlled.

How the site is run

Covered openings, the crew in proper protection, offcuts bagged rather than swept into the cavity, and a vacuum through the Westmount space at the end of the day rather than at the end of the job.

Kneewalls and the rooms in the roof

A cold face nobody sees

A kneewall in an Westmount 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.

Compression is the most common Westmount 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

Westmount 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.

Rim joists, the coldest part of a Westmount 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 Westmount 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.

Attic hatches, knee walls and the bits at the edges

Small areas, outsized effect

Knee walls in a Westmount 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.
