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.

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.

Will insulating an interior wall help with noise?

Yes, noticeably for voices and television, even when sound was not the reason for the job. If a bedroom or office wall is open anyway, upgrading that cavity to a denser batt costs very little on top.

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.

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 McKernan 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.

Mineral wool and fibreglass batts in McKernan walls and ceilings

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

What batts will not fix

Insulation is not air sealing

If a McKernan 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.

Wiring, boxes and the gaps behind them

Where the cold gets in

The fastest way to ruin a wall in McKernan 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.

Faced, unfaced, and the vapour question

Two systems

A kraft-faced batt carries its own vapour retarder; unfaced batts are paired with a separate poly barrier over the whole wall.

Why it matters here

Using both in the same McKernan assembly can trap moisture between two retarders. We pick one system for the wall and stay with it rather than mixing what is on the shelf.

Attic hatches, knee walls and the bits at the edges

Small areas, outsized effect

Knee walls in a McKernan 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.

Cathedral ceilings and leaving the air gap

Do not fill it completely

A vented cathedral ceiling in an McKernan home needs a clear air channel between the insulation and the roof sheathing.

Why

Packing the rafter bay full removes the ventilation that keeps the deck cold and dry, which is how a warm sloped ceiling ends up with a damp deck. Baffles hold the channel open.

Vapour control, and why the order matters

Warm side, always

In McKernan 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.
