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.

Is mineral wool worth it over fibreglass?

For sound, yes — it is denser, absorbs more energy in the cavity and holds its shape without sagging. It is a small material upgrade on a wall that is already open, which is where it earns its cost.

Which rooms in Lorelei 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.

Which single wall is the best value to do?

A bedroom sharing a wall with a living room or kitchen, especially if that wall is already open for other work. The noise is airborne, the improvement is obvious, and it is a small addition to work already scheduled.

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.

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.

Acoustic Insulation Lorelei Edmonton | Sound Batts

Acoustic insulation in Lorelei, the cavity half of the job

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.

Between-floor cavities in a Lorelei 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.

Lorelei drywall in context

About Lorelei

Lorelei is named for castle site on the Rhine in Germany.

What we see in Lorelei

In Lorelei 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.

Media rooms and the low-frequency problem

Bass is the expensive part

Acoustic batts in an Lorelei 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.

What acoustic batts actually do

Absorption inside the cavity

A dense batt in a Lorelei 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.

How we set the expectation before we start

What good looks like

After a properly filled and sealed Lorelei wall, normal conversation next door becomes an indistinct murmur rather than words you can follow. Television becomes background rather than content.

What it will not be

It will not be silence, bass will still come through, and a shared duct or a poor door will still let sound around it. Saying this before the wall closes is the difference between a good result and a disappointed one.

Home offices and the calls you do not want overheard

Two directions, not one

An Lorelei 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.

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 Lorelei 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.
