13330 Amberly Road     PO Box 273    Waverly, NE 68462    402-786-5017 Protection from the intrusion of airborne, footfall and other impact sounds starts with floors that reduce the passage of sound. Levelrock® brand floor underlayment systems are tested for their ability to isolate sound from multiple sources, providing an affordable acoustical solution that can significantly improve the privacy and comfort of any space. Minimizing sound intrusion can be complicated. Designing assemblies requires a fine balance between acoustic separation and fire protection - both elements are important to prevent owner and builder liability. Insulation thickness, placement in the cavity, and resilient channel spacing must all conform to the limits specified in the UL design. It is critical not to sacrifice fire ratings for sound ratings. The best way to improve sound performance for various floor coverings and still achieve a fire rating is to use a sound reduction mat or board beneath the floor underlayment.
