Artsonic® creates sound-rated floors with the high IIC and STC level required by ICBO, UBC and FHA for luxury developments. It is a durable and proven solution - the only mat that has been tested after 10 years of use. (Artsonic® retained 97% of original thickness, was as pliable as a new roll, and performed equally to a newly manufactured roll.) It increases IIC levels up to 12 points over wood frame, and up to 20 points over concrete. It also increases the STC rating 6-15 points over a bare wood frame system. Artsonic® is always "Green" with 40% pre-consumer recycled content. It is also offered with optional water resistant fabric.
