High-Performance Acoustic Floor Matting for Impact and Airborne Noise Reduction

Hushlay 15 Sound Matting is a high-performance acoustic floor mat designed to reduce impact noise and help improve airborne sound insulation through floor constructions.

Each sheet measures 1200mm x 1200mm x 15mm and covers 1.44m². The product uses a three-layer construction with two dense acoustic deadening layers and a frequency-tuned resilient core. This build-up helps reduce footfall noise, vibration transfer and sound movement through timber or concrete floor structures.

Hushlay 15 is suitable for residential and commercial flooring projects where stronger acoustic performance is required than a thinner underlay can provide. It can be used over timber or concrete floors and is commonly installed below carpet finishes. It can also be used with engineered or laminate timber flooring when installed with the correct Hush timber layer and full floor system specification.

For best results, Hushlay 15 should be installed as part of a complete acoustic floor build-up. Perimeter isolation, correct floor finish detailing and flanking noise control are important. Do not rely on the matting alone to solve all sound transfer issues.

5. Technical specifications

Hush confirms the key data: 1200 x 1200mm, 15mm thickness, 21.6kg per board, 15kg/m², use over timber or concrete floor structures, direct use under carpet, and use with engineered/laminate flooring when paired with the suitable Hush timber layer.

Acoustic performance

Hush Acoustics publishes typical acoustic performance figures of 47dB impact and 61dB airborne for Hushlay 15 when used as part of a tested floor structure. These results are based on the matting being installed over a floor structure with a suitable ceiling treatment and flanking paths removed.

Actual performance will depend on the full floor build-up, ceiling construction, floor finish, workmanship and flanking noise control.

Hush’s own page states the typical results and makes clear they are based on Hushlay 15 being used over a floor structure with suitable ceiling treatment and flanking paths removed.

Installation notes

Install Hushlay 15 over a clean, dry and level timber or concrete floor structure. Sheets should be laid tightly together with joints butted closely to avoid acoustic weak points.

Where the product is used below carpet, the carpet grippers should be isolated from the floor using suitable perimeter strips. This helps prevent rigid contact points that can reduce acoustic performance.

For engineered or laminate timber flooring, Hushlay 15 should be used with the correct timber layer or floor build-up specified by the manufacturer. Always check the final floor finish requirements before installation.

Avoid leaving gaps around walls, pipes, thresholds or service penetrations. Flanking paths can seriously reduce the performance of an acoustic floor system.

FAQ section

What is Hushlay 15 used for?

Hushlay 15 is used to reduce impact noise and help improve airborne sound insulation through floor constructions. It is commonly used in acoustic floor upgrades for homes, flats, offices and commercial buildings.

What size is each sheet?

Each sheet is 1200mm x 1200mm x 15mm and covers 1.44m².

How heavy is Hushlay 15?

Each sheet weighs approximately 21.6kg, equal to around 15kg/m².

Can Hushlay 15 be used under carpet?

Yes. Hushlay 15 can be laid directly below carpet floor finishes. Carpet grippers should be isolated using suitable perimeter strips.

Can it be used under laminate or engineered wood flooring?

Yes, but only when used with the correct timber layer or floor build-up. Do not install laminate or engineered timber directly without checking the required system.

Does Hushlay 15 meet Part E?

It can help a floor system meet acoustic requirements, but it should not be sold as a standalone Part E guarantee. Performance depends on the complete floor and ceiling construction, installation quality and flanking noise control.
