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.

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.

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 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.

Can batts go straight against my Suder Greens 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.

Batt insulation in Suder Greens before the vapour barrier goes on

Most of what separates good batt work from bad in Suder Greens 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 around plumbing on an exterior wall

Pipes belong on the warm side

A water line run in an Suder Greens 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.

Insulating a Suder Greens basement wall against concrete

Not the same as a framed wall above grade

A basement wall in Suder Greens 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 Suder Greens basement smells musty a year later.

Faced, unfaced, and the vapour question

Two systems

A kraft-faced batt carries its own vapour retarder; unfaced batts are paired with a separate poly barrier over the whole wall.

Why it matters here

Using both in the same Suder Greens assembly can trap moisture between two retarders. We pick one system for the wall and stay with it rather than mixing what is on the shelf.

Rim joists, the coldest part of a Suder Greens 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 Suder Greens 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.

Compression is the most common Suder Greens 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

Suder Greens 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.

Attic hatches, knee walls and the bits at the edges

Small areas, outsized effect

Knee walls in a Suder Greens 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.
