The dB Difference

Stopping sound waves is not just about a floor's thickness.

dB-4 is a unique material that combines a dense, flexible layer of protection with a fibrous insulation layer. This formula is able to trap sounds of all different wavelengths and keep them out of your space! Compatible with ceramic tile, wood and carpet.


dB-4 is made from high-quality raw materials to ensure optimum performance.

dB-4 is also 100% recyclable at end-of-life.

LEED credits are available with the use of dB-4.

Unlike PVC, our EVA does not harden over time or pose health risk if burned.

dB-4 Real-World Performance

The dB-4 out performs the untreated floors at each frequency, though the difference in performance varies by frequency. These values represent a single layer of dB-4. It is best to prepare your structure for all frequencies of sound to ensure the most comfort.
