Soundproofing Insulation in the Lower Mainland, BC
Western Insulation installs sound-rated insulation in ceilings, floors and walls for legal basement suites, home theatres, bedrooms and offices across Langley, Metro Vancouver and the Fraser Valley. For suites, we build toward the BC Building Code’s STC 43 separation between units, working with your contractor on drywall and resilient channel.
How Soundproofing Insulation Works
Sound-absorbing insulation stops noise echoing inside wall and ceiling cavities. On its own it adds only a few STC points – the big gains come when it’s combined with heavier drywall, resilient channel and sealed gaps.
Absorbs airborne noise in the cavity
Works with mass and decoupling
Seals flanking paths
Where Soundproofing Makes the Biggest Difference
Legal basement suites
The ceiling and shared walls between the suite and the main home.
Home theatres and media rooms
Keep movie sound in and household noise out.
Bedrooms and home offices
Quieter rooms next to bathrooms, laundry or busy streets.
Townhouses and strata units
Shared walls and floors between units – see strata and commercial insulation.
Soundproofing Materials We Use
Insulation Options
Mineral wool batts
Dense, non-combustible batts that absorb sound well – our first choice for suite ceilings.
Acoustic fibreglass batts
Lighter, cost-effective cavity fill for interior walls; see batt insulation.
Acoustic sealant
Seals perimeter gaps and penetrations so sound can't leak around the assembly.
Coordination with drywall
We install insulation ready for resilient channel and double Type X drywall by your contractor

What Our Customers Say
Are There Rebates for Soundproofing?
No. BC Hydro’s rules say insulation installed for soundproofing isn’t eligible for insulation rebates. If you’re renovating anyway, insulating exterior walls or crawlspace walls at the same time can qualify – see our rebates page.
Current BC Rebates Include
Potential rebates for dual-purpose acoustic and thermal insulation
Additional incentives when combining with other energy improvements
Limited-time bonuses for comprehensive home energy retrofits

Frequently Asked Questions
How much does soundproofing insulation reduce noise?
Sound-absorbing insulation in a wall or ceiling cavity usually adds only a few STC points on its own. Combined with resilient channel, two layers of 5/8-inch Type X drywall and sealed gaps, a typical suite ceiling can reach the BC Building Code’s STC 43 minimum. Footstep noise also depends on the flooring above.
What does BC require between a legal suite and the main house?
Under the BC Building Code, a house with a secondary suite needs a sound separation of at least STC 43, or ASTC 40 for the complete assembly, plus a fire separation, generally 45 minutes. Check with the Township or City of Langley before you build or legalise a suite.
Can you soundproof existing walls without opening them?
For walls that are already closed, meaningful soundproofing needs the drywall opened so sound insulation, resilient channel and new drywall can be installed. Ceilings for legal suites are usually opened.
Does soundproofing insulation qualify for BC Hydro rebates?
No. BC Hydro’s insulation rebate rules say insulation installed for soundproofing is not eligible, because rebates are for reducing heat loss from the home. Insulating exterior walls, the attic or crawlspace walls during the same renovation can still qualify when an HPCN contractor does the work.
Which rooms benefit most from soundproofing?
The ceiling and shared walls of basement suites benefit most, followed by home theatres, bedrooms next to bathrooms or laundry, home offices and walls shared with a neighbouring townhouse. Improving the floor above with carpet and underlay helps a lot with footsteps.
