QT IMPACT SOUND ISOLATION
|
A Big Impact On Interior Environment
Today's lightweight structures pose many challenges for architects and engineers. Impact sound reduction within multilevel units is imperative in meeting building codes and delivering high levels of acoustic control and privacy for interior space.
Highest IIC Rating
While many methods for reducing sound impact are available, no one product, on a stand alone basis, can match the IIC (Impact Insulation Class) ratings of QT- Sound Insulation. A sheet product, in continuous lengths, made from 100% recycled rubber, QT- Sound Insulation achieves higher impact sound reduction ratings than the industry according to ASTM standards E989-89 and E492-90. With IIC product ratings up to 25, QT- Sound Insulation outperforms cork, polyethylene, fiberglass and nylon matrix.
Lowest System Height
The QT- Sound Insulation single ply system not only ranks as the largest contributor to impact sound reduction, but also offers one of the lowest system heights in the industry. It doesn't need a suspended ceiling to produce required IIC ratings and eliminates the need for ramping between rooms while allowing floor and ceiling heights to be increased.
Typical QT - Sound Insulation Construction
Versatile
Product range and versatility are important to builders and architects alike. QT- Sound Insulation offers thickness options that produces exceptional results under hard surface flooring – over concrete and wood joist constructions. Custom thickness' are also available.
