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.

Many floor underlayment manufacturers rely on field tests to promote products. However, since all buildings are constructed differently, consistent test methods and conditions are essential to ensure that products meet the requirements of the 2003 International Building Code (IBC). All Levelrock floor underlayments are tested under laboratory conditions at NVLAP-accredited facilities in accordance with ASTM E492 and Section 1207 of the 2003 IBC. It may be more expensive to test in a laboratory, but the reliability of the results is more important than cost.
