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.

Can you insulate my finished walls without removing the drywall?

Not with batts — they need an open cavity. That is a job for a blown-in or injected product, or for adding insulation on the room side. We will tell you that rather than sell you a partial job.

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.

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.

Does the garage wall need anything special?

Usually yes — a fire separation as well as insulation, planned together because the board is specified. Insulation and vapour control go in and get inspected, then the rated board goes on.

Do you cut batts to fit?

Yes. Real Rapperswill 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.

Batt insulation in Rapperswill, fitted rather than stuffed

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

Batts friction-fit to full cavity width, not compressed
Vapour control detailed before the board goes on

Kneewalls and the rooms in the roof

A cold face nobody sees

A kneewall in an Rapperswill storey-and-a-half has attic space directly behind it, so the back of that batt is exposed to outdoor air.

What it needs

The batt supported and its back face covered, rather than left open to the attic where air washes straight through it. Uncovered kneewall insulation is one of the most common finds in older homes.

Cutting to the bay, not the label

Real framing is not nominal

Rapperswill 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.

Sound as a side effect of insulating

You get some for free

Filling an interior Rapperswill wall cavity with batts noticeably reduces voice and television noise between rooms, even when sound was not the reason for the job.

Where to spend a little more

If a bedroom, office or bathroom wall is being opened anyway, upgrading that specific cavity to a denser acoustic or mineral wool batt costs very little on top of work already happening. We will point out which walls those are while we are quoting.

Handling, dust and leaving it clean

Practical realities

Batt work makes airborne fibre and it settles everywhere if the space is not controlled.

How the site is run

Covered openings, the crew in proper protection, offcuts bagged rather than swept into the cavity, and a vacuum through the Rapperswill space at the end of the day rather than at the end of the job.

Insulating around plumbing on an exterior wall

Pipes belong on the warm side

A water line run in an Rapperswill 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.

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 Rapperswill 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.
