A Different Job Than Thermal Insulation

Soundproofing insulation is about comfort and privacy, not energy loss, which puts it in a different category from attic or wall insulation work aimed at an R-value target. The goal here is reducing how much sound passes through an interior wall or floor assembly between two rooms, two units, or two levels of the same house. Because interior partitions are not part of the building envelope, an exterior-wall material chosen for its R-value is not automatically the right choice for an interior wall chosen for its sound-dampening properties, which is why we use a different material for this job.

Where Soundproofing Insulation Helps

Shared Walls, Floors & Ceilings Between Units

Duplexes, townhouses, and multi-unit properties where noise transfer between units is common. Insulation added within a floor cavity to reduce footstep and voice transfer.

Home Theatre or Music Rooms

Interior walls around a dedicated media room, practice space, or home studio.

Bedrooms Next to Noisy Areas

A bedroom or home office wall shared with a laundry room or stairwell.

Materials Used for Sound Control

Mineral wool is the material of choice here, and here is why.

Mineral Wool (Rock Wool) Batts

Denser than standard fiberglass batts.

Fitted to the Existing Cavity

Batts are cut and fitted into the stud wall or floor joist cavity you already have.

Soundproofing insulation reduces the amount of sound that transfers through a wall or floor assembly, it does not fully eliminate it, and the result depends on the rest of the assembly as much as the insulation itself. Pricing depends on the number of walls or floors involved and how accessible the cavity is, so we confirm the scope and price after a free on-site assessment.

Ottawa Insulation Experts provides professional soundproofing insulation throughout Ottawa, Ontario. We install acoustic mineral wool insulation in interior walls and floors between rooms or units, for homeowners dealing with noise transfer rather than a heat loss problem. This is a distinct job from thermal insulation, aimed at comfort and privacy instead of energy efficiency, and it uses a different material chosen specifically for sound-dampening rather than R-value.

Soundproofing Insulation FAQs

Does soundproofing insulation also improve temperature control?

It can add some thermal benefit to an interior wall, but that is not what it is chosen for. Interior walls are not part of the building envelope, so the goal here is sound reduction, not R-value.

What is the difference between soundproofing insulation and regular wall insulation?

Regular wall insulation targets exterior walls and an R-value for heat retention. Soundproofing insulation uses denser mineral wool in interior walls or floors specifically to dampen sound transfer between rooms.

Will this fully eliminate noise between rooms?

No single product eliminates sound transfer completely. Mineral wool insulation reduces how much sound passes through the assembly, and the overall result depends on the rest of the wall construction as well.

Can soundproofing insulation be added without removing drywall?

In most cases the wall or floor cavity needs to be opened to fit the insulation properly, so this is usually planned alongside a renovation or a wall you are already opening.

Is this the same material used in exterior walls?

No. We typically use denser mineral wool batts for sound control, rather than the fiberglass batts or spray foam used for exterior wall thermal insulation.
