I insulated the wall and still hear next door. Why?

Usually a flanking path — a shared floor, a continuous ceiling cavity, a duct crossing both rooms, or the gap under the door. The weakest path sets the result, so we look for it before recommending the wall.

Will acoustic insulation stop my neighbour's television?

It will make it substantially harder to follow, which for most people is the goal. It will not make the wall silent, and it does much less for bass than for speech.

Can you add acoustic insulation to a wall that is already finished?

Not without opening it. If the wall is staying closed, the practical route is adding mass and damping on the room side. We will tell you what that realistically achieves before you decide.

We insulated the wall and can still hear each other. Why?

Often a shared duct run. Sound travels down the metal and through the openings, going around the wall entirely. That is a mechanical fix — lined duct or a silencer — not an insulation one.

What should I realistically expect afterwards?

Conversation next door becomes an indistinct murmur rather than words you can follow, and television becomes background. It will not be silence, and bass will still come through.

Do I need to seal as well, or is the insulation enough?

You need to seal. A perfectly filled cavity behind an unsealed perimeter still leaks sound — gaps at the floor and ceiling and back-to-back outlets carry it straight past the batts.

Sound batts in Stewart Greens bedrooms, offices and theatres

Acoustic insulation is one lever of four. Mass, decoupling, damping and sealing are the others, and a cavity full of good batts behind an unsealed perimeter still leaks sound. We would rather explain that first than have you pay for batts and be disappointed.

Ceilings between floors

The most requested, the most complex

Footsteps overhead are impact noise transmitted through structure, not airborne sound passing through a cavity.

What actually helps

Insulation in the joist space helps the airborne half — voices, television. The impact half needs decoupling or floor treatment above. In an Stewart Greens bi-level we explain which half we can address from below.

Bathrooms, and the reason people actually ask

Plumbing noise as much as voices

In an Stewart Greens home the complaint about a bathroom wall is usually the drain stack rather than conversation. That is structure-borne noise travelling through the pipe and the framing it touches.

What helps

Wrapping the stack and filling the cavity both help; decoupling the pipe from the framing helps more. Insulation alone will soften it rather than remove it, which is worth knowing before the wall closes.

Sealing, which decides how much of it you keep

Sound follows air

A perfectly filled Stewart Greens cavity behind an unsealed perimeter still leaks. Gaps at the floor and ceiling, back-to-back outlets and unsealed penetrations carry sound straight past the insulation.

Order of work

Sealing happens before boarding, which means it has to be planned into the sequence rather than added afterwards. It costs little compared to the batts and it protects the money already spent.

Worth doing during a renovation

Insulating the floor cavity between levels makes a real difference to voices and television carrying between floors. It is straightforward while a ceiling is open and disruptive afterwards.

Footsteps are the exception

Impact noise from above needs the ceiling decoupled. If footsteps are the actual complaint, batts alone will underdeliver and we would rather tell you that while the ceiling is still open.

Flanking paths around a good wall

Sound goes around

A well-built acoustic wall in an Stewart Greens home can be undone by a shared floor, a continuous ceiling cavity, a duct crossing both rooms, or a gap under the door.

Why we walk it first

Spending on one wall while the sound arrives by another route is the most common wasted acoustic budget. The weakest path sets the result, so we look for it before recommending the wall.

Setting the expectation before we start

Reduction, not silence

Acoustic batts in an Stewart Greens wall make normal speech harder to follow and take the edge off television. They will not make a room silent, and they will not stop a subwoofer.

Why we say it first

The gap between what people expect and what a cavity full of insulation delivers is the usual reason a sound job disappoints. It is a better conversation before the wall is closed than after.
