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 it stop footsteps from upstairs?

Not on its own. Footsteps are structure-borne — they travel through the framing, not the air in the cavity. That needs decoupling, such as resilient channel, with the insulation as one part of the assembly.

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 stop footsteps from upstairs?

Partly. Insulation in the joist space handles the airborne half — voices, television. Footsteps are impact noise through structure, which needs decoupling or floor treatment above. We explain which half we can address from below.

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.

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 Queen Alexandra Edmonton | Sound Batts

Sound batts in Queen Alexandra 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 Queen Alexandra we ask what you are hearing before quoting, because insulation alone is the wrong answer to half the problems people call about.

Home offices and the calls you do not want overheard

Two directions, not one

An Queen Alexandra home office has two sound problems: the household hearing your calls, and your calls picking up the household. Both are airborne, which is exactly what cavity insulation addresses well.

The door is the weak point

Once the wall is filled, the door becomes the limiting factor — a hollow-core door with a gap under it undoes much of the wall. We will say so rather than let you pay for a wall and be disappointed by a door.

Queen Alexandra drywall in context

About Queen Alexandra

Queen Alexandra, named for the wife of Edward VII of England, was once part of the original Town of Strathcona.

What we see in Queen Alexandra

In Queen Alexandra the drywall work is plaster and lath repair, popcorn and stipple ceiling removal, careful patching into original surfaces. We confirm what your home actually needs on site, in writing, before anything starts.

Nurseries and bedrooms next to living space

The most common real request

A bedroom sharing a wall with a living room or kitchen in Queen Alexandra is the case where acoustic batts perform best: the noise is airborne, the wall is usually being opened anyway, and the improvement is immediately obvious.

Cheap to add during other work

If that wall is open for electrical or a renovation, upgrading the cavity is a small addition to work already scheduled. It is the single best value acoustic job we do.

Doors and the gap at the bottom

The cheapest big win

A hollow-core door with an inch of air under it passes more sound than the entire wall around it.

Order of operations

On an Queen Alexandra room where the wall is staying closed, a solid door with a seal and a sweep often does more than any insulation upgrade would have, for less money. We say so even though it is not drywall work.

Flanking paths around a good wall

Sound goes around

A well-built acoustic wall in an Queen Alexandra 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.

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 Queen Alexandra cavity edge to edge and top to bottom, friction-fit, cut around wiring rather than stuffed past it.

Mineral wool versus fibreglass for sound

Density is the point

Both slow heat; for sound the denser mineral wool batt absorbs more energy inside the cavity, and it holds its shape in the bay without sagging.

Where it earns its cost

In an Queen Alexandra bedroom, office or shared wall it is a small material upgrade on a wall that is already open. On a wall you are not opening anyway, the labour dominates and the material choice matters less.
