Manufactured from high-density recycled rubber, it achieves 54dB of impact noise reduction in a slim 3mm profile — making it one of the most effective eco-friendly acoustic underlays available for residential and commercial flooring in the UK.
The recycled rubber composition delivers long-lasting resilience that foam and fibreboard alternatives cannot match. It will not compress, crack, or lose acoustic performance over time — ensuring your floor continues to perform acoustically for its full lifespan. Its moisture-resistant surface makes it suitable for concrete and timber subfloors alike, offering true versatility across all domestic and commercial flooring applications.
Best Acoustic Underlay for Laminate Flooring — Recycled Rubber Performance
When selecting the best acoustic underlay for laminate flooring with sustainable credentials, this 3mm recycled rubber underlay is the clear choice. The density of recycled rubber provides superior grip and stability beneath laminate planks — preventing edge-lifting, movement, and the squeaking that is common with cheaper foam underlays over time.
Its 3mm profile adds minimal height to the floor build-up, making it ideal for renovations where doorway clearances are a constraint, or in properties where multiple rooms are being refloored simultaneously and consistent floor heights are required at doorway transitions. Despite its slim profile, the recycled rubber delivers 54dB of impact noise reduction — performance that foam underlays of similar thickness cannot approach.
Soundproof Underlay Part E — Recycled Rubber Compliance
Yes — this soundproof underlay Part E compliant product is suitable for use in acoustic flooring systems meeting the requirements of Approved Document E of the UK Building Regulations. Its 54dB impact noise reduction rating makes it appropriate for use in residential flat conversions, new-build properties, and HMOs where Part E compliance is required.
As a recycled rubber product, it also aligns with the growing emphasis on sustainable construction materials in modern building projects. Where acoustic performance and environmental responsibility are both priorities, this recycled rubber underlay is the natural specification choice for developers, contractors, and homeowners alike.
Sound Deadening Underlay for Floors — How Recycled Rubber Achieves Results
Recycled rubber is the gold standard material for sound deadening underlay for floors. Its dense, granular matrix — formed from recycled tyre rubber — provides exceptional vibration absorption, dissipating impact energy before it can travel through the floor construction and emerge as structure-borne noise in the room below.
This 3mm underlay creates a resilient decoupling layer between the hard floor surface and the subfloor, breaking the direct connection that would otherwise transmit every footstep directly into the structure of the building. By absorbing and dampening this vibration energy, the underlay creates a measurably quieter environment — reducing footfall noise, chair movement, and other everyday impact sounds to a level that is significantly less intrusive to occupants in adjacent rooms and floors below.

Frequently Asked Questions
Does this recycled rubber acoustic underlay meet Part E Building Regulations?
Yes. This 3mm recycled rubber acoustic underlay achieves 54dB of impact noise reduction and is suitable for use in Part E compliant flooring assemblies for flat conversions, new-build properties, and HMOs. For full building control sign-off, we recommend confirming the complete system specification with your acoustic consultant or building control officer.
What is recycled rubber underlay made from?
This acoustic underlay is manufactured from recycled rubber granules, primarily derived from end-of-life vehicle tyres. The granules are processed, cleaned, and bonded together under heat and pressure to create a dense, uniform acoustic underlay product. Using recycled rubber diverts waste material from landfill and reduces the carbon footprint of the product compared to virgin rubber or foam alternatives — making it an environmentally responsible choice for flooring projects.
Is recycled rubber underlay better than foam underlay?
For acoustic performance and longevity, yes — recycled rubber significantly outperforms foam underlay. Foam underlays tend to compress over time, losing their acoustic properties and allowing the floor to develop a soft, uneven feel underfoot. Recycled rubber maintains its density and performance for the life of the floor. It also provides better impact noise reduction per millimetre of thickness, meaning you get more acoustic performance from a thinner product compared to foam.
How much acoustic underlay do I need?
Measure your room length × width in metres to get the floor area in square metres. Add 10% for cuts and wastage around door frames, fitted furniture, and alcoves. Select the roll size that covers your required area. For example, a 4m × 5m room = 20m² plus 10% wastage = 22m² needed. Choose a roll that covers at least this area, or combine smaller rolls for irregular-shaped spaces.
Can this underlay be used with underfloor heating?
Yes — this 3mm recycled rubber acoustic underlay is compatible with both electric and water-fed underfloor heating (UFH) systems. Its relatively low thermal resistance allows efficient heat transfer from the UFH system through to the floor surface. This makes it an excellent choice for open-plan living spaces and ground-floor rooms where both underfloor heating and acoustic comfort are priorities.
