Today's lightweight structures pose many challenges for architects
and engineers. Impact sound reduction within multi-level 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 achieves higher impact sound reduction
ratings then 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.
Guaranteed Results QT- Sound Insulation's
Certified System Guarantee assures a required IIC rating for your
specified construction
