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.

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

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.

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.

Can you insulate my finished walls without removing the drywall?

Not with batts — they need an open cavity. That is a job for a blown-in or injected product, or for adding insulation on the room side. We will tell you that rather than sell you a partial job.

Why is my Queen Mary Park 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.

Batt insulation in Queen Mary Park before the vapour barrier goes on

Most of what separates good batt work from bad in Queen Mary Park 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.

Insulating an existing Queen Mary Park wall without opening it

The honest limits

Batts need an open cavity. If a Queen Mary Park wall is finished and staying finished, batts are not the product — that is a job for a blown-in or injected material, or for adding insulation on the room side.

What we say

We would rather tell you batts are the wrong answer for a closed wall than sell you a partial job. Where the wall is already open for other work, that is the moment to insulate properly.

Queen Mary Park drywall in context

About Queen Mary Park

Lying just north of the City's business district in what was once the old Hudson Bay Company Reserve, this inner-city neighbourhood was not fully developed until the 1950s.

What we see in Queen Mary Park

In Queen Mary 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.

Compression is the most common Queen Mary Park 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

Queen Mary Park 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.

Wiring, boxes and the gaps behind them

Where the cold gets in

The fastest way to ruin a wall in Queen Mary 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.

Mineral wool against fibreglass in Queen Mary 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 Queen Mary Park, fibreglass fitted well beats mineral wool fitted badly.

Rim joists, the coldest part of a Queen Mary Park 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 Queen Mary Park 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.

Vapour control, and why the order matters

Warm side, always

In Queen Mary Park 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.
