QuietSound™ Acoustical Underlayment

QuietSound™ Acoustical Underlayment is the premium solution to abate noise transmission from foot traffic and electronics in multi-story buildings. Acting as a crack suppression membrane, QuietSound™ resists compression while offering superior underfoot comfort. Unlike natural cork and foam, this recycled rubber product will remain permanently resilient and impervious to the elements.

Whether used as a floating floor or bonded to the subfloor, QuietSound™ acoustical underlayment provides superior sound insulation that creates undisturbed living and working conditions for decades.

Why is QuietSound™ the premier solution to abate noise transmission from foot traffic and electronics in multi-story buildings?  It all starts with resilience.  QuietSound™ resists permanent compression while offering excellent underfoot comfort.  This acoustical rubber underlayment properly deflects compression when put under stress (e.g., the pressure of a footstep) and returns to its original form when not under stress.  Cork and foam underlayment products are not resilient and often remain permanently compressed just after a year of use. As a result, the sound insulation for these inferior underlayment products will decline significantly and rapidly following initial use.

QuietSound™ acoustical underlayment is suitable for all conventional subfloors and floor coverings.  QuietSound™ is easy to install using QuietGrip™ adhesive or an approved rubber bonding adhesive.

Installing Acoustical Underlayment

Proper installation of QuietSound™ Acoustical Underlayment is the responsibility of our customers. Unapproved adhesives can result in permanent damage and are not covered under our 25-year limited warranty. A premium grade adhesive, such as QuietGrip™, with high moisture resistance (up to 8 lbs./90% RH) that is specially formulated to provide maximum bond strength while helping to minimize plank shrinkage, is required for the offer the highest caliber tack and peel strength.
