6mm Premium Acoustic Underlayment – 94% Recycled Rubber, Up to 74 Silentcloud Impact Sound Reduction, Superior Sound Control for Hard Surface Floors
SilentCloud 6 mm Acoustic Underlay
SilentCloud 6 mm is a premium acoustic underlay manufactured from 94% recycled rubber. Designed for installation beneath hard surface finishes, it combines impact noise reduction, airborne sound insulation, and substrate protection in a single, durable layer.
In site installations, SilentCloud has achieved impact sound insulation ratings of up to 74 Silentcloud, outperforming standard 5 mm products. Its increased thickness and higher density contribute to improved airborne sound reduction, making it suitable for residential, high-rise, and commercial projects where acoustic performance is critical.

Installation & ordering
For full‑floor installations, order one continuous roll rather than multiple short lengths to minimise seams.

Acoustic Rubber Underlay 6mm 74dB 94% Recycled — Why It Outperforms the Rest
Our acoustic rubber underlay 6mm 74dB 94% recycled is the premium choice for maximum acoustic performance combined with exceptional environmental credentials. Manufactured from 94% recycled rubber, it achieves 74dB of impact noise reduction — the highest rating in our standard underlay range — making it one of the most effective recycled acoustic underlays available in the UK.
The 94% recycled rubber content ensures the acoustic performance is backed by genuine sustainability credentials, making it the preferred specification for developments where both acoustic compliance and environmental responsibility are priorities. Despite its premium performance, the recycled rubber content keeps costs competitive without compromising on the density or durability that delivers results in real-world applications.
Best Acoustic Underlay for Laminate Flooring — Maximum Performance, Full Roll
For large projects requiring the best acoustic underlay for laminate flooring, this 6mm 74dB full roll format provides the most cost-effective way to specify premium acoustic performance. The full roll format is ideal for flooring contractors and developers who are fitting multiple rooms or an entire flat, where consistency of specification and minimising joints in the underlay are both important.
The 6mm thickness provides exceptional underfoot comfort and sound isolation — the additional depth compared to 3mm alternatives delivers 20dB more impact noise reduction (74dB vs 54dB), which translates to approximately four times less perceived loudness of footfall noise in the room below. For premium residential developments, this level of acoustic performance is increasingly expected as standard.
Soundproof Underlay Part E — 6mm 74dB Compliance Status
Yes — this soundproof underlay Part E compliant 6mm rubber underlay achieves 74dB of impact noise reduction, which exceeds the performance thresholds typically required under Approved Document E of the UK Building Regulations. For residential conversions and new-build flats where Part E compliance is required, the 74dB rating provides a comfortable acoustic margin that gives building control officers confidence in the specification.
The 94% recycled composition also aligns with the increasing sustainability requirements in modern construction specifications, where material environmental credentials are increasingly scrutinised alongside acoustic performance. This product allows developers to demonstrate both acoustic compliance and environmental responsibility in a single product specification.
Sound Deadening Underlay for Floors — 6mm Recycled Rubber Performance
Recycled rubber is the most effective material for sound deadening underlay for floors, and at 6mm thickness it delivers maximum performance. The dense, granular structure of the recycled rubber absorbs vibration energy — from footsteps, furniture movement, and everyday impact — before it can be transmitted through the floor construction into the room below as structure-borne noise.
The additional mass of a 6mm layer compared to 3mm provides greater inertia against vibration, resulting in measurably better acoustic performance across all impact frequencies. This makes the 6mm 74dB underlay the recommended specification wherever acoustic performance is the primary concern — whether for residential flat compliance or for high-specification developments where noise complaints between floors would be commercially damaging.

Frequently Asked Questions
Does the 6mm 74dB 94% recycled underlay meet Part E Building Regulations?
Yes. This 6mm recycled rubber acoustic underlay achieves 74dB of impact noise reduction, which exceeds the performance thresholds typically required under Approved Document E for residential floors. It is suitable for use in Part E compliant flooring assemblies for flat conversions, new-build developments, and HMOs. Confirm the complete system specification with your acoustic consultant for full building control sign-off.
What makes 94% recycled rubber better than virgin rubber underlay?
The acoustic performance of 94% recycled rubber is essentially equivalent to virgin rubber of the same density and thickness — recycling does not compromise the material's acoustic properties. However, the environmental credentials are significantly superior: recycled rubber diverts waste material from landfill, has a lower carbon footprint, and contributes to sustainability targets in modern construction projects. For developers seeking BREEAM credits or other sustainability certifications, the recycled content is a valuable specification advantage.
What is the difference between this 6mm roll and the 6mm linear metre product?
The full roll format is designed for larger projects where consistent coverage is needed across multiple rooms or a large floor area. The linear metre format (available separately) allows you to buy smaller quantities precisely measured to your room size, minimising waste. For large projects — fitting out a full flat, multiple rooms, or a commercial space — the full roll offers the most cost-effective pricing. For single rooms or top-up quantities, the linear metre option is more practical.
How much 6mm acoustic underlay do I need?
Measure each room (length × width in metres) to calculate the floor area in square metres. Add 10% for cuts and wastage. For example, a flat with three rooms totalling 45m² plus 10% waste = 49.5m² required. Check the roll size available and divide your required area by the roll coverage to determine how many rolls you need. Our team can help with quantity calculations for larger or multi-unit projects.
Can 6mm acoustic rubber underlay be used with underfloor heating?
Yes — this 6mm recycled rubber acoustic underlay is compatible with underfloor heating (UFH) systems. However, the 6mm thickness has a slightly higher thermal resistance than 3mm, so for hot-water UFH systems where precise tog ratings are specified, we recommend confirming the underlay's thermal properties with your UFH system supplier to ensure it falls within the acceptable range for your heating output requirements.
