Should we insulate between floors?

It helps a lot with voices and television between levels and is straightforward while a ceiling is open. It does much less for footsteps, which need the ceiling decoupled — worth knowing while the ceiling is still accessible.

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.

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.

Is acoustic batt different from ordinary insulation?

Yes, it is denser, which is what makes it better at absorbing sound. Ordinary fibreglass in a cavity still helps compared to an empty bay, but acoustic or mineral wool batts do more per inch.

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.

Which rooms in Wellington are actually worth doing?

Bedrooms against living space, a home office, a theatre, and any wall between two dwelling units. An interior wall between two similar rooms rarely justifies the upgrade, and we will say so.

Acoustic Insulation Wellington Edmonton | Sound Batts

Sound batts in Wellington bedrooms, offices and theatres

Acoustic batts absorb airborne noise inside a wall cavity — voices, television, music. They do very little for footsteps or bass, which travel through the structure. In Wellington we ask what you are hearing before quoting, because insulation alone is the wrong answer to half the problems people call about.

Filling the cavity completely

Gaps undo it

An acoustic batt with a gap at the top of the bay leaves an open air path across the wall. Sound follows it exactly as heat would, and the wall performs closer to an empty one than a filled one.

Compression too

Squashing a batt in also reduces performance. The batt should fill the Wellington cavity edge to edge and top to bottom, friction-fit, cut around wiring rather than stuffed past it.

Flanking paths around a good wall

Sound goes around

A well-built acoustic wall in an Wellington 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.

Media rooms and the low-frequency problem

Bass is the expensive part

Acoustic batts in an Wellington media room wall do good work on dialogue and mid-range. Low frequency passes through cavity insulation almost unaffected because it moves the structure itself.

Setting the budget honestly

If the goal is that nobody upstairs hears the movie, the assembly needs mass and decoupling as well, and the door and any ducting have to be dealt with. If the goal is that it is not intrusive, filled cavities and sealing get you a long way for much less.

Ducting, the path everyone forgets

A shared duct is a speaking tube

Two Wellington rooms connected by the same duct run will hear each other regardless of what is in the walls. Sound travels down the metal and through the openings.

What can be done

Lined duct, flexible sections and duct silencers all help, and they are a mechanical job rather than an insulation one. We flag it when we can see it, because filling the wall will not fix a path that goes around the wall.

Between-floor cavities in a Wellington two-storey

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.

Floors and ceilings between Wellington levels

The joist space

Insulating the floor cavity between levels helps meaningfully with voices and television from the room below or above. It is a common and worthwhile addition during a basement development.

Impact noise is different

It will do much less for footsteps. If that is the complaint, the ceiling needs decoupling — resilient channel or a similar assembly — and the insulation becomes one part of a larger build rather than the whole answer.
