Description
Professional Acoustic Rubber Underlay – Engineered for Maximum Sound Insulation Performance
Specify with confidence. Our high-density acoustic rubber underlay delivers certified 78 dB reduction in both impact (IIC) and airborne (STC) sound transmission, providing proven noise control for residential, commercial, and industrial floor installations across the UK.
- Free UK Delivery – no hidden £90+ delivery surcharges common with other acoustic underlay suppliers
- 9 Stocked Thicknesses (1.5mm–12mm) – sold by the linear metre so you pay only for what you need, with zero waste
- Free Technical Support – acoustic calculations, U-value data and installation guidance from our specialists before you buy
- Fast UK Dispatch – stock held regionally with trade and bulk pricing available
Acoustic Performance Specification
- Impact Insulation Class (IIC): Up to 78 dB reduction – eliminates footfall, dropped objects, and structure-borne vibration
- Sound Transmission Class (STC): Up to 78 dB airborne attenuation – blocks voices, music, and ambient noise transfer between floors
- Material Engineering: Vulcanised high-density rubber barrier mat with optimised acoustic mass
- Compression Set Resistance: Maintains dimensional stability and acoustic performance under sustained loading
- Flanking Transmission Control: High-mass construction minimises lateral sound paths
Building Regulations & Compliance
Engineered to meet and exceed UK Building Regulations Part E (England & Wales) and Section 5 (Scotland) for separating floors in new builds, conversions, and change-of-use projects. Suitable for acoustic pre-completion testing (PCT) and robust detail specifications.
Applications: Multi-occupancy residential (flats, apartments, HMOs), commercial fit-outs, recording studios, broadcast facilities, home cinemas, gyms, dance studios, educational buildings, healthcare facilities, and hospitality venues requiring certified acoustic separation.
Installation & Compatibility
- Floating Floor Systems: Compatible with laminate, engineered timber, LVT, luxury vinyl plank, and click-lock flooring
- Underfloor Heating: Low thermal resistance – consult technical data for UFH compatibility and tog rating
- Subfloor Preparation: Installs over concrete, screed, timber joists, and existing solid floors
- Cutting & Handling: Cuts cleanly with standard tools – no specialist equipment required
- Adhesive-Free Installation: Friction-fit for most floating applications – reduces labour time and VOC emissions
Technical Data & Performance Metrics
- Density: High-mass vulcanised rubber (optimised for acoustic damping)
- Thickness: 1.5mm to 12mm (nine thickness options available – see product variants above)
- Roll Width: 1.25m standard (2.0m width also available on the 3mm option)
- Fire Rating: Contact our technical team for project-specific fire rating documentation
- Thermal Resistance (R-value): Low thermal resistance – suitable for underfloor heating; contact us for tog rating data specific to your project
- VOC Emissions: Low-emission formulation suitable for BREEAM/LEED projects
Why Acoustic Consultants & Contractors Choose Slip-Not
Proven track record supplying acoustic solutions to UK construction professionals. Our high-density rubber underlay is specified by acoustic engineers, M&E consultants, and main contractors for projects requiring verifiable noise control performance, regulatory compliance, and long-term reliability.

Frequently Asked Questions
Q: Does this underlay meet Part E Building Regulations?
A: Yes. When installed correctly as part of a compliant floor build-up, this high-density acoustic rubber underlay achieves the required airborne and impact sound insulation values for separating floors under Part E (England & Wales) and Section 5 (Scotland).
Q: Can I use this with underfloor heating?
A: Yes, subject to thermal resistance calculations. Consult our technical team for tog rating and compatibility with your specific UFH system to ensure optimal heat transfer and acoustic performance.
Q: What's the difference between IIC and STC ratings?
A: IIC (Impact Insulation Class) measures reduction of impact noise like footsteps. STC (Sound Transmission Class) measures airborne noise like speech or music. This underlay addresses both transmission paths for comprehensive sound insulation.
Q: How much do I need for my project?
A: Calculate total floor area in square metres, then divide by roll width to determine linear metres required. Add 5-10% for cuts and wastage. Our team can provide project-specific material take-offs.
Q: Is installation difficult?
A: No. The underlay rolls out flat, cuts easily with a utility knife, and requires no adhesive for most floating floor installations. Standard trade skills are sufficient – no acoustic specialist required for installation.
Q: How does this compare to other acoustic underlays on the market?
A: Unlike many competing acoustic underlay listings, we publish transparent, per-linear-metre pricing with no minimum order – many other suppliers add £90 or more in delivery charges once you reach checkout. You also get a genuine choice of 9 stocked thicknesses, free pre-sales technical support from our team, and certified 78 dB combined impact and airborne performance, so you can specify with confidence rather than guesswork.
