NEW Acousti-Mat? 3 is the sound deadening solution for floor systems that have been impossible to control! Now you can put an end to those “noise” complaints – even with open beam, concrete slab and conventional wood frame systems. Acousti-Mat? 3 consists of a nylon core of fused, entangled filaments attached to a non-woven fabric, similar to Maxxon”s Acousti-Mat II , only three times thicker. It”s a proven fact that the larger the air space, the greater the sound control – and this system creates the largest air void of any sound control mat. The results – up to an additional 5 db improvement in impact noise control, over the already high sound control provided by Acousti-Mat II . This is a 15 IIC (impact noise) rating point improvement over a conventional wood frame construction! And 10 points represents a doubling of performance and would sound twice as good to the human ear. The additional mass of the floor system also increases the STC (airborne noise) rating. [URL=][/URL]
