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.

What about the wiring in the wall?

The batt gets split so part sits behind the cable and part in front, and it is cut around boxes. Stuffing it behind the wiring leaves an uninsulated void right where there is already a hole in the vapour barrier.

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.

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.

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.

Batt insulation in Evergreen before the vapour barrier goes on

A batt only performs if it fills the cavity completely and is not squashed. In Evergreen 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.

Cathedral ceilings and the ventilation gap

Do not fill it to the deck

In a vaulted Evergreen 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.

Evergreen drywall in context

About Evergreen

Evergreen is a mobile home park is nested in a beautiful, naturally wooded ravine in north east Edmonton.

What we see in Evergreen

In Evergreen the drywall work is verify dominant band before writing notes. We confirm what your home actually needs on site, in writing, before anything starts.

Compression is the most common Evergreen 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

Evergreen 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.

Mineral wool against fibreglass in Evergreen

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 Evergreen, fibreglass fitted well beats mineral wool fitted badly.

Cutting to the bay, not the label

Real framing is not nominal

Evergreen walls, especially in older homes and renovations, carry bays that are wider or narrower than standard, plus cripples, blocking and services.

What we do

Measure and cut. A batt forced into a narrow bay is compressed and underperforms; one left short in a wide bay leaves a gap that convects. Both are invisible after boarding.

Garage-to-house walls and ceilings

Two jobs at once

The wall between an Evergreen garage and the house, and the ceiling under living space, usually need a fire separation as well as insulation. The two have to be planned together because the board and the assembly are specified.

Sequencing

Insulation and vapour control go in, get inspected, then the rated board goes on. Doing it in the wrong order means opening a finished rated assembly, which is the expensive way to discover the sequence.

Batts around ducts and services

What is on the cold side

A duct or pipe run through an exterior Evergreen 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.
