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 pipes in my exterior wall?

Insulation goes behind them, between the pipe and the outside, not stuffed in around them. A water line on the cold side of the batt is a freeze risk in an Alberta winter, not just an efficiency question.

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

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.

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 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.

Batt insulation in Ellerslie Edmonton, fitted rather than stuffed

A batt only performs if it fills the cavity completely and is not squashed. In Ellerslie Edmonton the two things that ruin it are compression — jamming a wider batt into a narrow bay — and gaps around wiring and boxes, where the insulation is stuffed behind rather than split around.

Split and fitted around wiring and electrical boxes
Batts friction-fit to full cavity width, not compressed
Vapour control detailed before the board goes on
Rim joists insulated and air-sealed
Odd bays cut to fit rather than packed
Mineral wool where fire or sound performance matters

Cathedral ceilings and the ventilation gap

Do not fill it to the deck

In a vaulted Ellerslie Edmonton ceiling there has to be an air channel between the insulation and the roof sheathing. Packing batts tight to the deck closes it, and the roof has no way to dry.

What that costs later

Damp sheathing, mould and in the worst cases rot — none of it visible until it is expensive. The batt is sized so the channel stays open, which means accepting slightly less insulation depth in exchange for a roof that lasts.

What batts will not fix

Insulation is not air sealing

If a Ellerslie Edmonton 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.

Attic hatches, knee walls and the bits at the edges

Small areas, outsized effect

Knee walls in a Ellerslie Edmonton 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.

Insulating a Ellerslie Edmonton basement wall against concrete

Not the same as a framed wall above grade

A basement wall in Ellerslie Edmonton 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 Ellerslie Edmonton basement smells musty a year later.

Rim joists, the coldest part of a Ellerslie Edmonton 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 Ellerslie Edmonton 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.

Batts around ducts and services

What is on the cold side

A duct or pipe run through an exterior Ellerslie Edmonton 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.
