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.

Will insulation stop the echo in my room?

No — that is a different problem. Cavity insulation reduces sound passing through a wall; echo inside a room needs surface treatment. We ask which one you have before quoting, because buying the wrong one is common.

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.

Will it stop the bass from my basement theatre?

Not on its own. Batts work well on speech and mid frequencies; low frequency travels through structure and needs mass and decoupling too. We would rather set that expectation at the quote than after.

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.

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.

Acoustic Insulation Hollick-Kenyon Edmonton | Sound Batts

Acoustic insulation in Hollick-Kenyon, the cavity half of the job

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 Hollick-Kenyon we ask what you are hearing before quoting, because insulation alone is the wrong answer to half the problems people call about.

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 Hollick-Kenyon bi-level we explain which half we can address from below.

About Hollick-Kenyon

The neighbourhood was named after Herbert "Bertie" Hollick-Kenyon, who piloted flights over the Antarctic as part of the first mapping of that territory.

What we see in Hollick-Kenyon

In Hollick-Kenyon the drywall work is first-year settling, basement dev for first owners, Level 5 over builder-grade. We confirm what your home actually needs on site, in writing, before anything starts.

Between-floor cavities in a Hollick-Kenyon 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.

Absorption is not blocking

Two different problems

Batts in a cavity reduce sound passing through a wall. Panels on a wall surface reduce echo inside the room. People often buy one expecting the other.

Getting the right one

If your Hollick-Kenyon room sounds boomy and hard, that is reverberation and cavity insulation will not fix it. If you hear the next room clearly, that is transmission. We ask which one you actually have before quoting.

What acoustic batts actually do

Absorption inside the cavity

A dense batt in a Hollick-Kenyon wall cavity absorbs sound energy that would otherwise resonate in the empty space between the two board faces. For airborne noise — speech, television, music — that is a real and measurable improvement.

What they do not do

They do not decouple the wall. Footsteps overhead and bass through a shared wall travel through the framing itself, and no amount of cavity insulation interrupts that path.

Floors and ceilings between Hollick-Kenyon 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.

Where it is worth doing on a whole house

Prioritising

Insulating every interior partition in an Hollick-Kenyon home is rarely the best use of the budget.

What we suggest

Bedrooms, the wall between a bathroom and living space, an office, a media room, and the ceiling under an upstairs bedroom. Those five carry most of the benefit; the rest is largely unnoticed once you are living in the house.
