Acoustic Underlayments for Nail Down Solid Hardwood

Soundeater underlayment for nail down hardwood is the most recent development in the field of sound reducing sub-flooring designed for 3/4" solid and 14-15mm semi-solid hardwood flooring.

Soundeater combines a specially designed tongue and groove impact absorbing soft board with a mating wooden profile. The profile is placed free from the substrate between the soft boards every 10 1/2". The top side of the profile will accept a 1 1/2" flooring nail on a 45 degree angle through 3/4" hardwood without touching the sub floor. The result is a totally free floating hardwood floor.

Soundeater systems have been installed in condominiums, apartments, hotels and resorts in living areas. In addition, it has been installed in commercial and public buildings to prevent high-traffic passages on the floors above from intruding conference, office, and meeting areas.
