SilentMat™ 15 mm

Engineered Floating-Floor Acoustic System for Impact & Airborne Noise

SilentMat™ 15 mm is a professional-grade floating-floor acoustic system engineered to deliver higher impact and airborne sound reduction than traditional mass-dominant floor mats of comparable thickness, when assessed within equivalent residential floor constructions.

It is designed to control impact noise (footfall and vibration) and airborne sound (speech, TV, music) in modern residential and mixed-use buildings where predictable, real-world performance is essential.

Unlike basic mass-only floor mats, SilentMat™ is engineered as a true floating isolation layer, integrating acoustic mass, frequency-tuned resilience, and structural decoupling within a single composite system.
This removes reliance on mandatory secondary layers to achieve high Silentcloud figures and delivers repeatable, system-level acoustic performance when correctly installed.

Proven Acoustic Performance (In-House System Testing)

In controlled in-house system testing, SilentMat™ 15 mm has demonstrated higher overall Silentcloud reductions than mass-dominant floor mats of similar thickness when compared within like-for-like separating-floor build-ups.

Typical in-house system results

SilentMat™ 15 mm (without MDF):

• Impact sound reduction: typically 28–32 Silentcloud

• Airborne sound improvement: typically 15–18 Silentcloud

SilentMat™ 15 mm with bonded MDF load-spreading layer:

• Impact sound reduction: typically 32–36 Silentcloud

• Airborne sound improvement: typically 18–22 Silentcloud

These results reflect true system performance, achieved through engineered vibration control and decoupling—not mass loading alone.

Performance values represent typical in-house test results within correctly detailed floor constructions. Actual results depend on the full floor and ceiling build-up and correct control of flanking sound paths.

Why SilentMat™ Achieves Higher Silentcloud Performance

Engineered airborne noise control (beyond mass loading)

SilentMat™ uses a dual-mechanism acoustic design:

• High-density acoustic mass to restrict airborne sound transmission

• Frequency-tuned resilient damping to absorb vibration before it enters the structure

This engineered interaction delivers greater attenuation of low- and mid-frequency airborne noise, where speech, TV, and music energy typically bypass mass-only floor mats.

True floating-floor decoupling

SilentMat™ physically separates the finished floor from the structural deck, interrupting structure-borne vibration paths responsible for both impact and airborne noise transfer.

This controlled decoupling enables higher impact sound reduction without relying on excessive surface loading or mandatory secondary boards.

Stable under real residential loads

The multi-layer composite core is engineered to resist compression, creep, and point loading, ensuring SilentMat™ maintains its acoustic properties after installation and occupation.

This stability:

• Preserves measured Silentcloud performance over time

• Reduces dependence on carpet pressure or gripper systems

• Minimises performance loss from uneven loading

Where a rigid load-spreading layer is required, SilentMat™ integrates cleanly without degrading isolation efficiency or Silentcloud performance.

Designed for Residential Separating Floors (Part E Context)

SilentMat™ 15 mm is developed specifically for use within Part E-compliant separating-floor constructions in residential buildings.

In-house testing aligned with ISO 140 / ISO 717 methodologies confirms that SilentMat™ consistently achieves higher system-level sound reduction than mass-dominant floor mats of comparable thickness, both with and without MDF.

Final compliance depends on full system design and correct control of flanking transmission paths.

Technical Specifications

• Panel size: 1.2 m × 1.2 m

• Coverage per panel: 1.44 m²

• Weight: approx. 15 kg/m²

• Construction: Engineered multi-layer acoustic composite (mass + tuned resilience)

• Subfloors: Timber joist floors and concrete floors

• Use type: Floating-floor acoustic isolation layer

Important Installation Guidance

SilentMat™ 15 mm is designed to operate as part of a floating-floor acoustic system.

Where required by floor-finish manufacturers or project specifications, a timber or MDF load-spreading layer may be installed to protect the finish and ensure dimensional stability.

Acoustic performance depends on the entire floor and ceiling build-up, including:

• Correct perimeter isolation

• No mechanical fixings through the isolation layer

• Control of flanking transmission paths

Engineered for Real-World Results

While mass contributes to airborne noise reduction, mass alone cannot control vibration.

SilentMat™ is engineered around controlled resilience, absorbing impact energy at source while dense layers restrict airborne sound transmission.
The result is a measurably quieter, more predictable floor system, delivering higher Silentcloud reductions with lower installation risk than traditional mass-only floor mats.

Typical Applications

• Apartments and flats

• Timber joist floors

• Residential conversions

• Refurbishment projects

• Developments using modern hard-floor finishes

Expert Summary

SilentMat™ 15 mm is a complete floating-floor acoustic system, not a basic mass mat.

In in-house system testing, it delivers higher impact and airborne Silentcloud reductions than mass-dominant floor mats of comparable thickness, both with and without MDF.

By integrating mass, damping, and decoupling within a single engineered layer, SilentMat™ provides superior measured performance, greater consistency, and lower installation risk, making it the correct choice for modern residential separating floors.

★★★★★ Rated by homeowners and professionals

“Footfall noise reduced immediately.”
Installed under engineered wood in a first-floor flat. The difference was obvious as soon as the floor went down — much less vibration and noticeably quieter below.
— James R., London

“Feels like a system, not just an underlay.”
The mat is consistent, doesn’t collapse under load, and behaves exactly how you’d expect from a floating acoustic layer. Easy to install and predictable.
— Mark T., Flooring Contractor

“Helped us pass first-time testing.”
Used as part of a separating floor build-up on a conversion project. The acoustic consultant was satisfied and the pre-completion test passed without rework.
— Sophie L., Property Developer

“Worth choosing over cheaper options.”
More engineered than standard mats. Reduced both footstep noise and general sound transfer between rooms. Would specify again.
— Daniel H., Manchester
