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 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.

Do you cut batts to fit?

Yes. Real Starling framing carries bays wider or narrower than nominal, plus cripples and blocking. Forced batts are compressed and underperform; short ones leave gaps that convect. Both are invisible after boarding.

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.

Will insulating an interior wall help with noise?

Yes, noticeably for voices and television, even when sound was not the reason for the job. If a bedroom or office wall is open anyway, upgrading that cavity to a denser batt costs very little on top.

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.

Mineral wool and fibreglass batts in Starling walls and ceilings

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

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

Vapour control, and why the order matters

Warm side, always

In Starling 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.

Mineral wool against fibreglass in Starling

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 Starling, fibreglass fitted well beats mineral wool fitted badly.

Friction fit, not stapled tight

How a batt is meant to sit

An unfaced batt holds itself in an Starling 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.

Garage-to-house walls and ceilings

Two jobs at once

The wall between an Starling 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.

What batts will not fix

Insulation is not air sealing

If a Starling 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.

Rim joists, the coldest part of a Starling 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 Starling 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.
