Acoustic insulation in Legacy, for rooms that need to be quieter

Most of the noise that travels between rooms is airborne — voices, a television, a laundry machine — and the cheapest time to do anything about it is while the wall is open. In Legacy we install acoustic batt and mineral wool into wall and floor cavities, filled edge to edge and uncompressed, before the board goes up. Legacy is one of SW Calgary's newer communities, where fresh installation and first-year settling work are common, so basements here are typically open-concept with generous ceiling height for a drop grid. We cover Legacy, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of acoustic insulation in Legacy?

Area, material and access

Acoustic insulation cost in Legacy comes down to the wall or floor area being treated, the material — mineral wool costs more than standard batt and performs better for sound — and whether the cavity is already open or has to be opened up. We measure and give a fixed price before we start.

Open walls are far cheaper

Treating a Legacy wall that is already open during a renovation or a new build costs a fraction of coming back to it later.

What acoustic batt does — and what it does not

What it does

Acoustic batt absorbs airborne noise inside the cavity — conversation, television, music, appliances. A filled cavity is noticeably quieter than an empty one, and in most Legacy homes it is the single biggest improvement available for the money.

What it does not do on its own

Batt in the cavity will not stop impact noise travelling through the structure — footsteps overhead, a door slamming, something dropped on the floor above. It also will not help if sound is going around the wall through a shared duct, a gap under a door or a hollow-core door itself.

Where the assembly comes in

Stopping impact and structural noise takes changes to how the wall is built — that is our soundproofing work, and the two are usually done together on the same wall. Ceilings in Legacy are typically knockdown, and matching that pattern is the part of a repair people notice.

How we install acoustic batt in Legacy

Full cavity, cut to fit

We cut each piece to the cavity and friction-fit it so it fills the bay completely in your Legacy wall. Gaps at the top plate, around outlets or at the edges are where sound gets through, and a compressed batt performs worse than a correctly sized one.

The places most crews skip

The narrow bays beside doors and windows, the space behind electrical boxes and the cavity above a dropped ceiling all get filled — those are the gaps that undo the rest of the work. New homes in Legacy tend to have long unbroken wall runs and high ceilings, which changes how a seam has to be feathered.

Common acoustic insulation situations in Legacy

In Legacy, legacy is a community still building out. Homes there are current-build, so ceilings are typically knockdown and the work is new-build boarding and taping, basement development, and the first-season movement that shows up as a house dries out. One fixed price after an honest on-site look, and the job done right the first time.

Why Legacy homeowners have us do the acoustic insulation

We are the ones closing the wall

As a drywall company we install acoustic batt the way we want to board over it — full fill, no gaps — because we are the trade that closes the wall in Legacy and we do not get a second chance at it.

How Legacy homes affect the work

Because the homes in Legacy are still new, most of what we find is first-season movement rather than damage — hairline cracks at corners and the odd nail pop as the framing dries out.

Ceilings here are typically knockdown, and matching that spray pattern is the part people notice if it is done badly — so we test the match before committing to the whole ceiling.

Builder deficiency work is common in Legacy — nail pops, corner cracks and seams that only appeared after possession.

Acoustic Insulation Legacy: your questions answered

Will acoustic insulation make the room completely quiet in Legacy?
No — and anyone who tells you otherwise is overselling it. Filling the cavity makes a room noticeably quieter for airborne noise like voices and television. Getting further than that means changing how the wall is built, which we can also do.
How is acoustic batt different from regular insulation in a Legacy home?
Acoustic batt and mineral wool are denser than standard thermal batt, which is what makes them better at absorbing sound in the cavity. Standard batt does help, but the denser material does more for the same space.
Can you insulate between floors in Legacy?
Yes — the floor cavity between a main floor and a basement or an upstairs bedroom is one of the most common places we install acoustic batt, and it is straightforward while the ceiling is open.
Do I need resilient channel in my Legacy home as well?
It depends what is bothering you. For voices and television through a wall, filling the cavity is usually enough. For footsteps and impact noise from above, the cavity alone will not do it and the assembly has to change too.
Should acoustic batt go in both sides of a party wall in Legacy?
A party wall normally has one cavity, and we fill it completely rather than treating it as two jobs. If the wall is a double-stud assembly we fill both. We also cover Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant.
