Description
What is a 6 mm acoustic rubber underlay and why use it?
This dense 6 mm acoustic rubber underlay absorbs impact noise and reduces airborne sound transmission between floors and walls. It cushions floors, protects subfloors and improves comfort underfoot. Use it under laminate, hardwood, tile or carpet to dampen footfall noise, prevent impact damage and enhance living and working spaces.
What makes this underlay unique?
• Dual noise reduction: Cuts impact noise by up to 74 dB and reduces airborne noise by 5–10 dB thanks to its high-density structure.
• Eco-friendly composition: Made from 94% recycled rubber granules bonded with a flexible polyurethane binder.
• Moisture-resistant: Resists rot and mould, making it suitable for kitchens, bathrooms and basements.
• Underfloor heating compatible: Conducts heat evenly without impeding performance.
• Easy to cut and install: Sheets and rolls can be trimmed with a utility knife; butt joints together and tape seams.
• Versatile applications: Use under laminate, engineered wood, carpet tiles, LVT, stone or between stud walls and ceilings.
How do you install or use this underlay?
1. Measure your space and calculate the quantity needed.
2. Clean and dry the subfloor so it is free of dust and debris.
3. Cut the underlay to size using a straight edge and utility knife.
4. Lay the underlay with rubber granules facing down and butt edges together; tape seams with acoustic tape.
5. Install your floor covering: float laminate or engineered wood over the underlay, or use a flexible adhesive and decoupling membrane for tiles and stone.
6. Optional: Use this underlay on walls or ceilings by attaching panels with adhesive or mechanical fixings.
7. Clean and maintain: Wipe with a damp cloth or vacuum; no special maintenance is required.
Why choose this underlay over alternatives?
• Superior noise reduction compared to foam and cork underlays in both impact and airborne sound.
• Long lifespan: High-density rubber retains performance for decades without compressing.
• Multi-purpose: Suitable for floors, walls and ceilings for maximum soundproofing.
• Eco-conscious choice: Made from recycled materials with minimal environmental impact.
• Cost-effective: Offers professional soundproofing at an affordable price per square metre.
