Quiet Step Combi-lay Acoustic Underlay

Quiet-Step Combi-Lay is a superior underlay, where reduced reflected foot noise and sound reduction in multi-story buildings are required. It is made of high-density polyolefin copolymer resin which effectively reduces the hollow and often “clunky” foot noise associated with floating floors. Quiet-Step Combi-Lay addresses this key negative of floating floor installations while performing all the tasks of a superior quality underlay including a continuous damp proof*.

Quiet-Step Combi-Lay is the first floating floor underlay in Australia to take reflected foot noise seriously. Independent University tests show a 30% or more reduction in reflected foot noise for the user, while the underlay has achieved an excellent L’ntw + C1 = 44 ratings in multi-story applications.

The integrated damp proof removes the need for additional damp-proof layers in most instances*, while the product’s strength and lay flat characteristics make it a pleasure to install.
