Our soundproofing rubber sheets are precision-engineered from high-density SBR rubber to deliver exceptional sound deadening, vibration damping, and impact noise reduction across floors, walls, ceilings, and machinery enclosures. Available in seven thicknesses from 3mm to 25mm, cut to your exact size, and dispatched from UK stock.✅ Why Choose Our Soundproofing Rubber Sheet? Blocks up to 75dB of airborne noise — measurable, real-world sound attenuation across all thicknesses Superior vibration damping — high-density rubber mass absorbs structure-borne impact noise at source Part E Building Regulations compliant — suitable for residential separating floors and walls Cut to size — ordered by the linear metre in 1m or 2m widths, no wastage UK stock, fast dispatch — next-day delivery available on standard sizes 7 thicknesses: 3mm, 4mm, 5mm, 6mm, 10mm, 15mm, 20mm, 25mm — scalable acoustic performance for every application Closed-cell structure — moisture-resistant and dimensionally stable in humid or wet environments Easy to install — flexible sheet that can be glued, screwed, or loose-laid 📐 Thickness Guide — Which One Do You Need? 3mm — lightweight acoustic underlay for laminate, LVT, and engineered floors; reduces footfall and impact noise 4–5mm — thin-profile wall lining behind plasterboard or timber panels; ideal for apartments and offices 6mm — versatile all-round soundproofing for floors, walls, and machinery bases; excellent cost-to-performance ratio 10mm — heavy-duty floor and wall acoustic barrier; effective against both airborne and impact sound 15mm — industrial and commercial applications; plant rooms, mechanical enclosures, recording studios 20mm — high-mass sound barrier for extreme noise environments; generator housings, compressor rooms 25mm — maximum acoustic performance; acoustic enclosures, anechoic chambers, heavy industrial isolation 🏗️ Where to Use Soundproofing Rubber Sheet Residential floors — Part E compliant acoustic underlay beneath timber, laminate, LVT, and screed Walls and ceilings — mass-loaded barrier behind stud walls, independent ceilings, and party walls Industrial machinery — vibration isolation pads, anti-vibration mounts, and machine base liners Mechanical enclosures — line ductwork, pipework lagging, fan housings, and HVAC enclosures Recording studios and home cinemas — primary decoupling layer combined with acoustic foam or plasterboard Automotive and marine — sound deadening sheets for vehicle floors, bulkheads, and engine bays Commercial and office fit-outs — separating floors, meeting rooms, and open-plan acoustic treatment 📦 Product Specifications Material: High-density SBR (Styrene Butadiene Rubber) Colour: Black Widths available: 1 metre / 2 metres Thicknesses: 3mm, 4mm, 5mm, 6mm, 10mm, 15mm, 20mm, 25mm Sold by: Linear metre Surface: Smooth both sides Temperature range: –30°C to +80°C Density: 1,400–1,600 kg/m³ (varies by thickness) Acoustic performance: Up to 75dB noise reduction (thickness dependent) Compliance: Part E Building Regulations (UK) Country of origin: UK 🔧 Installation Tips from Our Experts For floating floor applications, lay the sheet with a 50mm upstand against walls to prevent flanking sound transmission. Butt joints tightly and tape seams with acoustic tape. For wall linings, fix mechanically or with a contact adhesive, ensuring full contact to eliminate air gaps. For machinery isolation, cut to the exact footprint of the base — additional mass improves isolation efficiency. Always ensure the substrate is clean, dry, and flat before installation.Not sure which thickness is right for your project?
