Hear the Difference
These are actual recordings from independent acoustical lab tests — not simulations. Each clip captures real impact noise transmitted through the floor assembly. Soundstop was redesigned in 2024 for even higher performance.

All Four Tiers
Select the tier that matches your project's acoustical requirements and budget. Soundstop III and IV are the most specified for multi-family and hospitality.
Soundstop I
Entry Acoustical — Eliminates 1/8" Sound Mat
IIC 53
STC 61 / IIC 53 — Redesigned 2024. No separate sound mat required.
Soundstop I delivers certified acoustical performance with a 3mm profile and 12-mil wear layer. The factory-bonded acoustical backing eliminates the need for a separate 1/8" sound mat — saving $0.55/SF on every upper-floor unit.

Soundstop II
Mid-Grade Acoustical — Eliminates 1/8" Sound Mat
IIC 55
STC 62 / IIC 55 — Redesigned 2024. No separate sound mat required.
Soundstop II adds 0.5mm to the profile for improved dimensional stability and a slightly higher IIC rating. The 12-mil wear layer handles moderate commercial traffic while delivering STC 62 / IIC 55 — saving $0.65/SF versus a traditional LVT + 1/8" mat installation.

Soundstop III
Commercial Acoustical — Eliminates 1/4" Sound Mat
IIC 56
STC 63 / IIC 56 — Redesigned 2024. No separate sound mat required.
Soundstop III steps up to a 20-mil commercial wear layer and 4mm profile. It eliminates the more expensive 1/4" sound mat, saving $1.20/SF — the most popular tier for full-service hotels and mid-range multi-family developments.

Soundstop IV
Flagship Acoustical — Eliminates 1/4" Sound Mat
IIC 58
STC 64 / IIC 58 — Redesigned 2024. No separate sound mat required.
Soundstop IV is AFC's highest-rated acoustical product. The 5mm profile with 20-mil commercial wear layer achieves STC 64 / IIC 58 — the best acoustical performance available in a single-product glue-down LVT. Eliminates the 1/4" sound mat, saving $1.50/SF.

Why Soundstop Wins the Bid
One Product. One Install.
Traditional acoustical installations require two separate products (LVT + sound mat) and two separate installation steps. Soundstop's factory-bonded backing delivers both in a single glue-down operation.
Redesigned in 2024
The 2024 redesign improved the acoustical backing's bond strength and dimensional stability, resulting in higher IIC ratings and longer-term performance in high-traffic multi-family environments.
$0.55–$1.50/SF Savings
By eliminating the separate sound mat and its installation labor, Soundstop delivers $0.55–$1.50/SF in total installed cost savings. On a 182-unit project at 200 SF/unit, that's up to $54,600.
