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.

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.

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.

Will acoustic batts stop my home office calls being overheard?

They work well on that, because voices are airborne. Once the wall is filled the door usually becomes the limiting factor — a hollow-core door with a gap underneath undoes a lot of the wall.

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.

Acoustic insulation in Mayliewan: what it fixes and what it does not

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.

Sealing, which decides how much of it you keep

Sound follows air

A perfectly filled Mayliewan 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.

Mayliewan drywall in context

About Mayliewan

Mayliewan, named after a body of water was taken from the Cantonese word meaning "beautiful day".

What we see in Mayliewan

In Mayliewan the drywall work is popcorn and stipple ceiling removal, settling+truss-uplift cracks, nail pops, Poly-B repipe patching repipe patching. We confirm what your home actually needs on site, in writing, before anything starts.

How we set the expectation before we start

What good looks like

After a properly filled and sealed Mayliewan 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.

Low frequency is the hard part

What insulation does not solve

Batts work well on speech and mid frequencies. Bass from a theatre, a subwoofer or a furnace travels through structure and is far harder to stop.

Being straight about it

If the goal in an Mayliewan basement is that nobody upstairs hears the movie, insulation alone will not get there — it needs mass and decoupling too. We would rather set that expectation at the quote.

Home offices and the calls you do not want overheard

Two directions, not one

An Mayliewan 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.

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 Mayliewan 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.

Where acoustic insulation earns its money in Mayliewan in Edmonton

The rooms worth doing

Bedrooms against a living space, a home office against a hallway, a theatre, and any wall between two dwelling units. In those the difference between an empty cavity and a filled one is easy to hear.

Where it is not worth it

An interior wall between two rooms used the same way rarely justifies the upgrade. We will say so rather than quoting acoustic batts through a whole Mayliewan house.
