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.

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

Frequently Asked Questions
Does the SilentMat 15mm meet Building Regulations Part E?
Yes. The SilentMat 15mm Floating Floor System is designed to meet the requirements of Approved Document E of the UK Building Regulations for both impact and airborne sound insulation. Its 15mm construction delivers performance levels appropriate for use in residential conversions, new-build flats, and HMOs. We recommend confirming the complete system specification with your acoustic consultant for full building control sign-off.
What is the difference between impact noise and airborne noise?
Impact noise is generated by direct physical contact with the floor — footsteps, dropped objects, and furniture movement. Airborne noise is sound that travels through the air before passing through the floor structure, such as voices, music, and TV. The SilentMat 15mm addresses both types simultaneously, making it a complete acoustic solution for floors that need to meet dual performance requirements under Part E.
Is the SilentMat 15mm suitable for concrete or timber subfloors?
Yes — the SilentMat 15mm floating floor system is suitable for installation over both concrete and timber subfloors. It creates a floating floor assembly that is decoupled from the structural subfloor, which is the key mechanism for effective sound isolation. Installation guidance is provided with the product, and our technical team can advise on specific subfloor conditions that may require additional preparation before installation.
How much acoustic floating floor system do I need?
Calculate your floor area by measuring the length × width of each room in metres and multiplying together. Add 10% for cuts and wastage at perimeter edges and doorways. Select the quantity that covers your total area. For multi-room projects, calculate each room separately and sum the totals. Our team can provide quantity take-offs for larger projects if you supply floor plans or measurements.
Can the SilentMat 15mm be used with underfloor heating?
Please contact our technical team for specific guidance on UFH compatibility with the SilentMat 15mm floating floor system, as the interaction between floating floor assemblies and underfloor heating requires careful specification to ensure both acoustic performance and heating efficiency are maintained. We can advise on the appropriate system configuration for your specific project requirements.
