Product Information
Take the edge off footstep noise with Hush FFR 3mm Resilient Acoustic Underlay. Made from recycled rubber granules and fibres, it provides a thin, resilient layer beneath floor finishes on timber or concrete bases.
Each 20m x 1m roll covers 20m². At just 3mm thick, Hush FFR helps keep the floor build-up low in new builds and refurbishments.

Where to use Hush FFR 3mm
Use beneath floating laminate or engineered timber flooring, or beneath carpet. The fine rubber granulate is bonded with a PUR elastomer to combine resilience with resistance to compression.
For tiled finishes, Hush’s guidance specifies FFR beneath plywood and an anti-fracture membrane with flexible adhesive. Plan these extra layers into your floor height.
Acoustic performance for the 3mm underlay
Hush publishes 18 dB footfall sound insulation at 3mm under DIN EN ISO 140-8. This describes impact sound improvement from footfall; it is not an airborne sound rating.
Planning your installation
- Use Hush FFR 3mm as the resilient layer above a timber or concrete floor.
- Floating laminate and engineered timber can be laid directly over the underlay, following the floor-finish supplier’s fitting requirements.
- For stone or tiled finishes, include the specified plywood, anti-fracture membrane and flexible adhesive.
Hush supplies detailed FFR fitting instructions on request. Select the fixing or bonding method for your chosen floor finish before installation.
How many do I need?
Add your chosen allowance for joints and cuts to the room area, divide by 20m² and round up to whole rolls.
For example, a 35m² room with an optional 10% allowance needs 35 × 1.10 ÷ 20 = 1.925, rounded up to 2 rolls.
