Redupax®

Acoustic Underlayment for Floated Engineered Hardwood & Laminate Flooring.

Redupax is a 100% recycled wood fiber based underlay that will not bounce or flex like many foams, felts, and rubber underlays—resulting in a more stable and robust sound when walked upon, and eliminating the disagreeable “hollow sound” attributed to many floated engineered hardwood and laminate floors.

Redupax has a thickness of 9 mm and a density of 13 lbs per cubic foot and offers true stability, acoustics and thermal qualities. In addition, Redupax is also environmentally friendly FCS certified and bio degradable. Installed under floated engineered hardwood and laminate floors, Redupax proves time and again high quality, acoustic performance and reliability.
