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.

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.

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

My room is cold and draughty. Will batts fix it?

Probably not on their own. Draughts around windows, an unsealed rim joist or gaps at the top plate are air leaks, and insulation does not stop air. We would rather diagnose the draught and quote the sealing, which is usually the cheaper half.

Can batts go straight against my High Park 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 cut batts to fit?

Yes. Real High Park 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.

Batt insulation in High Park before the vapour barrier goes on

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

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 High Park space at the end of the day rather than at the end of the job.

High Park drywall in context

About High Park

High Park is a smaller neighbourhood laid out in a grid pattern and the lots are of a generous size.

What we see in High Park

In High Park 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.

Wiring, boxes and the gaps behind them

Where the cold gets in

The fastest way to ruin a wall in High Park 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.

Attic hatches, knee walls and the bits at the edges

Small areas, outsized effect

Knee walls in a High Park 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.

Sound as a side effect of insulating

You get some for free

Filling an interior High Park 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.

Cathedral ceilings and the ventilation gap

Do not fill it to the deck

In a vaulted High Park 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 High Park

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 High Park, fibreglass fitted well beats mineral wool fitted badly.
