The FS FC–1 is a high-performance acoustic floor system for new build concrete floors. The system will prevent noise on two levels, above the concrete and below.

The Hush FFR (db FFR) is a recycled rubber membrane that sits between the concrete and screed overlay, to help reduce the sound of footfall.

The Hush Slab, Fireline Plasterboard and ceiling bars are constructed beneath the concrete and support the ceiling below the floating floor.

The calculator tool to the right (underneath on mobile devices) will allow you to add your floor and room dimensions to quantify how much material you need for your soundproofing project.
