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.

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.

Why is my Kernohan 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.

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.

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 Kernohan 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.

Mineral wool and fibreglass batts in Kernohan walls and ceilings

Most of what separates good batt work from bad in Kernohan 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 a Kernohan basement wall against concrete

Not the same as a framed wall above grade

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

Kernohan drywall in context

About Kernohan

Named for an early pioneer farmer who operated a grocery store here in the 1880s and 90s, Kernohan was not annexed until 1961.

What we see in Kernohan

In Kernohan 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.

Sound as a side effect of insulating

You get some for free

Filling an interior Kernohan 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.

Friction fit, not stapled tight

How a batt is meant to sit

An unfaced batt holds itself in an Kernohan bay by friction across its full width, touching the framing on both sides and the sheathing behind.

The common shortcut

Pulling a faced batt tight and stapling the flanges to the face of the stud, which dishes the middle and leaves a void behind. It looks tidy from the room and performs worse than it measures.

Mineral wool against fibreglass in Kernohan

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 Kernohan, fibreglass fitted well beats mineral wool fitted badly.

Cathedral ceilings and leaving the air gap

Do not fill it completely

A vented cathedral ceiling in an Kernohan 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.

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 Kernohan space at the end of the day rather than at the end of the job.
