Key Benefits

• Practical entry-level upgrade for everyday noise and footfall — two layers of 5kg MLV combined with Silent Floor Ultra Underlay provide a meaningful improvement in both airborne and impact noise without structural work
• Dual 5kg MLV layers for added mass — two rolls of 5kg mass loaded vinyl with staggered joints add dense mass to help reduce everyday airborne noise including talking, TV, and general household noise
• Silent Floor Ultra Acoustic Underlay for impact isolation — installed above the MLV layers to reduce footfall and impact noise, and to provide a high-performance acoustic substrate directly under the carpet
• Suitable for carpet finishes — Silent Floor Ultra provides a compatible acoustic base for carpet installations without requiring adhesive bonding to the floor finish
• DIY-friendly installation — no structural work required; the system is laid over the existing floorboards and finished with carpet as normal
• Slim build-up depth — approximately 16mm overall, making it suitable for most rooms; check door and threshold clearances before ordering
• Built-in 5% waste allowance — calculator quantities include a 5% overage to reduce the risk of under-ordering on site

Important Notes 

• This system is designed for timber floors intended to be finished with carpet
• It is intended to improve both airborne noise and impact noise, but results will vary depending on the existing floor construction
• Sealant quantities are an approximation only and should be treated as a guide
• The calculator is provided as a guide only, and final quantities should always be checked before ordering
