Mineral wool and fibreglass batts in Strathearn walls and ceilings

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

Rim joists, the coldest part of a Strathearn 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 Strathearn 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.

What we see in Strathearn

In Strathearn 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 Strathearn space at the end of the day rather than at the end of the job.

What batts will not fix

Insulation is not air sealing

If a Strathearn room is cold because of draughts around windows, an unsealed rim joist or gaps at the top plate, filling the cavity with batts will disappoint you.

Why we say it first

We would rather diagnose the draught and quote the sealing than sell you insulation that does not solve the complaint. The two jobs go together, and the sealing is usually the cheaper half.

Insulating a Strathearn basement wall against concrete

Not the same as a framed wall above grade

A basement wall in Strathearn 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 Strathearn basement smells musty a year later.

Cathedral ceilings and the ventilation gap

Do not fill it to the deck

In a vaulted Strathearn 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.

Mineral wool against fibreglass in Strathearn

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 Strathearn, fibreglass fitted well beats mineral wool fitted badly.

Batt Insulation Strathearn Edmonton: your questions answered

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.
Can you fill my vaulted ceiling completely?
No, and it matters. There has to be an air channel between the insulation and the roof sheathing so the roof can dry. Packing it tight leads to damp sheathing and eventually rot, none of it visible until it is expensive.
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.
Do you cut batts to fit?
Yes. Real Strathearn 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.
Does the garage wall need anything special?
Usually yes — a fire separation as well as insulation, planned together because the board is specified. Insulation and vapour control go in and get inspected, then the rated board goes on.
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.
