This is EnkaSonic
The EnkaSonic product portfolio encompasses a range of acoustic sound insulation underlays designed for use in the most diverse floor systems. They all consist of a three-dimensional mat made of fused entangled synthetic monofilaments. These are thermally bonded to a nonwoven fabric.
EnkaSonic complies with relevant construction and building codes in the US and many European countries. If and as required the underlay can be customized to meet new national codes. EnkaSonic is highly compression resistant. Testing after 10 years of use has shown that the sound control mat had retained over 95% of its original thickness.
EnkaSonic is installed between the concrete or wood subfloor, and a gypsum or lightweight concrete topping to build a floating floor. It creates a void area within the floor construction.
This void isolates noise and prevents it from spreading. EnkaSonic so reduces the transmission of both airborne and impact sound.
The acoustic insulation underlay significantly increases Impact Insulation Class (IIC) ratings and Sound Transmission Class (STC) levels over wood frame and IIC over concrete.
