Installation & ordering

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

Sound Proof Acoustic Underlay 3mm — Why It Outperforms the Rest

Our sound proof acoustic underlay 3mm is manufactured from 94% recycled rubber, delivering 54dB of impact noise reduction in a slim, low-profile format. Available in linear metre cuts (1m to 10m), it offers maximum flexibility for both small and large flooring projects. Whether you're laying a single room or fitting out an entire flat, you can buy precisely the quantity you need — no waste, no leftover rolls.

Unlike single-size roll products, the cut-to-length format of this underlay makes it the preferred choice for professional flooring contractors and DIY installers alike. The recycled rubber composition ensures long-lasting resilience — it won't compress, crack, or lose its soundproofing effectiveness over time, unlike foam alternatives.

Best Acoustic Underlay for Laminate Flooring — Cut to Size, No Waste

For anyone looking for the best acoustic underlay for laminate flooring in a flexible format, this 3mm recycled rubber underlay is an excellent choice. The linear metre sizing (1m × 1m to 1m × 10m) means you can calculate your room area precisely and order exactly what you need. This is especially useful for irregular-shaped rooms, smaller spaces, or projects where you've already purchased underlay for the main area and just need a top-up.

The 3mm profile adds minimal height to your floor build-up — a critical factor in doorway clearances and adjacent room transitions — while still delivering 54dB of impact noise reduction. Its moisture-resistant surface is suitable for use on both timber and concrete subfloors.

Soundproof Underlay Part E — Does This Product Comply?

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. Part E requires that floors in flats and houses in multiple occupation (HMOs) achieve minimum standards for both airborne and impact sound insulation between occupancies.

This 3mm acoustic rubber underlay achieves 54dB impact noise reduction, placing it within the performance range used in many approved Part E flooring assemblies. For projects requiring full Part E sign-off from building control, we recommend confirming the complete system specification with your acoustic consultant to ensure all elements of the assembly meet the required performance thresholds.

Sound Deadening Underlay for Floors — How Recycled Rubber Delivers Results

Recycled rubber is widely recognised as the most effective material for sound deadening underlay for floors. Its dense, granular structure absorbs and dissipates vibration energy — such as the impact from footsteps — before it can be transmitted through the floor construction and perceived as airborne noise in the room below.

This 3mm underlay forms a resilient, vibration-absorbing layer between your hard floor covering and the subfloor, effectively decoupling the two surfaces and breaking the path for structure-borne sound transmission. The result is a noticeably quieter property — particularly important in flats, conversions, and any multi-storey property where noise between floors is a concern.

Frequently Asked Questions

Does this sound proof acoustic underlay meet Building Regulations Part E?

Yes. This 3mm recycled rubber underlay achieves 54dB of impact noise reduction and is suitable for use in acoustic flooring systems that meet the requirements of Approved Document E. It is appropriate for use in flat conversions, new-build properties, and HMOs where Part E compliance is required. For full compliance sign-off, the underlay should be part of a complete specified acoustic system — confirm with your acoustic consultant or building control officer.

What is the difference between buying per linear metre vs. a full roll?

Buying per linear metre gives you complete flexibility — you order exactly the size you need (from 1m² to 10m²) rather than purchasing a full roll that may leave you with significant waste. This is ideal for rooms where your calculated area doesn't match standard roll sizes, for top-up quantities, or for professional contractors who want to minimise off-cuts and material waste on site. Full roll options may offer a lower cost-per-square-metre for large projects.

Is this the best acoustic rubber underlay for flats?

For flats where floor height is limited and a slim-profile solution is needed, yes — this 3mm recycled rubber underlay is one of the best acoustic underlays for flats available in the UK. Its 54dB impact noise rating provides meaningful reduction in the footfall noise heard between floors, while the 3mm thickness adds minimal height to the floor build-up. Available in exact sizes, it's a flexible, cost-effective choice for residential flat conversions.

How much acoustic underlay do I need?

Measure the length and width of your room in metres and multiply together to get your floor area in square metres. Add 10% for cuts and wastage. Then select the closest linear metre option from our range. For example, a 4m × 3.5m room = 14m², plus 10% wastage = 15.4m² — you'd select the 1m × 10m option for your main area and the 1m × 5m or 1m × 6m option as a top-up, or simply order 16m² across two purchases.

Is this underlay compatible with underfloor heating systems?

Yes — this 3mm recycled rubber soundproofing underlay is compatible with electric and hot-water underfloor heating (UFH) systems. Its thermal resistance is low enough to allow efficient heat transfer from the UFH system through to the floor surface, while still delivering its acoustic insulation performance. This makes it an excellent choice for modern flats and open-plan living spaces where both underfloor heating and acoustic compliance are required.
