Professional Floor Soundproofing Installation Services
At Quiet Acoustics, we specialise in high-performance floor soundproofing solutions that eliminate the daily disturbance of footfall and airborne noise. Whether you are living in a timber-joist house or a modern concrete apartment, our systems provide the necessary resilience and mass to restore peace to your property.
Based in Henlow, our expert team provides specialist floor soundproofing across London, Hertfordshire, Buckinghamshire, Bedfordshire, and Cambridgeshire, serving major hubs including Milton Keynes, St Albans, Cambridge, Luton, and Watford.
Advanced Floor Insulation & Decoupling Systems
Effective floor soundproofing requires a dual approach: adding mass to block airborne sound (speech, TV) and introducing resilience to dampen impact vibrations (footsteps). We ensure all installations meet or exceed UK Building Regulations Part E standards.
-
Acoustic Floating Floor Systems: We install high-density floating floors that physically decouple your floor finish from the subfloor. Using engineered mats and acoustic decks, we interrupt the path of vibration, significantly reducing the "drum effect" typical of timber floors.
-
High-Mass Acoustic Underlays: For projects where floor height is a priority, we utilise slim-line, high-mass underlays. These composite layers add significant weight to block airborne sound without requiring extensive structural changes or door trimming.
-
Joist Infill & Isolation: For a comprehensive solution, we can treat the void between your floor joists with 100mm/60kg/m³ mineral wool insulation. Combined with isolation strips on top of the joists, this method achieves the highest possible level of acoustic isolation.

QuietMat Floor Underlay System

The Quietmat floor system is a premium floor soundproofing product that features strong performance against both airborne and impact noise. It is available for install on for both timber and concrete structures, and it is both slim and straightforward to install. To achieve the best possible solution for soundproofing, you will need to incorporate them into 'Systems'. Each offers ways of increasing acoustic performance, for example, by fitting them alongside acoustic cradles to create a fully floating floor, by adding them to joist structures alongside sound insulation for a vast improvement for airborne and impact noise or use in concrete buildings as a standalone for impact reduction. Contact us today to learn more about this acoustic underlayment for hardwood floors, tile floors, carpeted floors, and other types of flooring!
QuietMat Floor Underlay System

Quiet Cradle 16/30mm is our dual-height acoustic cradle system that offers a soundproof floating floor system that isolates away from concrete and timber floors, effective for the reduction of both impact and airborne sound. QuietCradle also allows you to produce a flat floor without the use of screed. Screed layers can often be an impractical form of underfloor soundproofing due to the long lead times, the use of sizeable machinery, and the cure times. Our QuietCradle Packers come in a range of sizes to help in fine-tuning any unevenness in the concrete floor.
Independent Floor System

Our Diamond independent Floor is our Best performing system. We construct a Timber frame completely detached from the current floor. With a minimum of 25mm space / gap between the ceiling below. The void is then filled with 100mm Acoustic insulation. The Floor is then lined with 1 layer of Acoustic plank then the Floor deck laid over with green glue sandwiched between.
