The dB Difference

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

dB-TOPSTOP is a unique material which 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!


dB-TOPSTOP is proudly made with post industrial recycled material that would otherwise be sent to a landfill.

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

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