STC 61

Airborne sound transmission — voices, TV, music — tested on a wood floor assembly with no separate sound mat.

IIC 56

Impact insulation — footsteps and dropped objects — with the acoustic backing attached directly under the wear layer.

HIIC 68

High-frequency impact — the metric that best predicts the quiet occupants actually perceive.

Headline results: Soundstop Glue Down, no soundmat, wood assembly. The full certified matrix — by report number — is below.

The Technology

Sound Control Built Into the Plank

Soundstop uses a BA-cored construction with an integrated acoustic backing, so the sound-dampening layer is bonded to the plank rather than shipped and installed separately. Painted beveled edges give a finished, monolithic look while the core does the acoustic work.

Integrated soundmat — no loose underlayment to source or install
Painted beveled edges for a clean, seamless visual
Deletes a material and a trade vs. a separate mat below gypsum
Commercial-grade wear layer for high-traffic multi-family and hospitality

Where Soundstop Performs

Built for the Buildings That Need Quiet

Multi-Family

Apartments and condos with unit-to-unit sound requirements between floors.

Hospitality

Hotels and short-term rentals where guest comfort depends on quiet rooms.

Senior & Student Housing

High-occupancy residential where footfall noise is a constant complaint driver.

Mixed-Use

Residential over retail or amenity space, where assemblies must control transmission.
