Hush FFR Recycled Rubber Resilient Underlay

educationleisure
Hush FFR Acoustic Rubber Underlay is a fully recycled rubber designed for use with both soft and hard flooring, such as Engineered timber, Laminate, Stone flooring and carpet, designed to absorb footfall noise and increase living standards within the construction, whether in residential or commercial applications. The material also has a Zero OPD (Ozone Depleting Potential) and Zero GWP (Global Warming Potential).

The specially selected Rubber particles and fibres are designed to give excellent resilience yet upmost compressive strength.

Hush FFR Resilient Underlay Impact has an excellent performance characteristic both on Concrete and Timber Floors, is easy to lay and very cost effective.
