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.

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.

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 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.

Should batts be stapled tight to the studs?

The face-stapling shortcut dishes the middle of the batt and leaves a void behind it. A batt should sit by friction across its full width, touching framing on both sides and the sheathing behind.

Batt insulation in Hairsine, fitted rather than stuffed

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

Batts around ducts and services

What is on the cold side

A duct or pipe run through an exterior Hairsine bay must have insulation behind it, between it and the outside, not merely stuffed in around it.

Consequence of getting it wrong

A water line on the cold side of the batt is a freeze risk in an Alberta winter, not just an efficiency question. It is worth the extra few minutes on each bay.

Hairsine drywall in context

About Hairsine

Hairsine was named for the first mayor of the town of Beverly and includes the Victoria Trail, which once led to the Old Victoria Settlement.

What we see in Hairsine

In Hairsine 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 Hairsine 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

Hairsine 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.

Insulating around plumbing on an exterior wall

Pipes belong on the warm side

A water line run in an Hairsine exterior wall cavity with the batt behind it is sitting on the cold side of the insulation. In February that is a freeze risk.

What we do

Wherever the plumbing allows, the insulation goes behind the pipe so the pipe stays in the heated space. Where it does not, we flag it rather than boarding over a line we know is exposed.

Attic hatches, knee walls and the bits at the edges

Small areas, outsized effect

Knee walls in a Hairsine 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 Hairsine 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.

Friction fit, not stapled tight

How a batt is meant to sit

An unfaced batt holds itself in an Hairsine 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.
