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.

Do you insulate knee walls and attic hatches?

Yes, and they matter more than their size suggests. They are direct openings between heated and unheated space, and a well-insulated wall next to a bare knee wall performs like the weaker of the two.

Why is my Glenwood 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.

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

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.

Mineral wool and fibreglass batts in Glenwood walls and ceilings

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

Glenwood drywall in context

About Glenwood

Glenwood is a large neighbourhood in the City's west end, and represents both residential and commercial land uses.

What we see in Glenwood

In Glenwood 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.

Mineral wool against fibreglass in Glenwood

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 Glenwood, fibreglass fitted well beats mineral wool fitted badly.

Compression is the most common Glenwood 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

Glenwood 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.

Cathedral ceilings and leaving the air gap

Do not fill it completely

A vented cathedral ceiling in an Glenwood 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 Glenwood 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.

Sound as a side effect of insulating

You get some for free

Filling an interior Glenwood 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.
