Description

3mm Premium Acoustic Underlayment — 94% Recycled Rubber, Up to 54dB Sound Proofing, Slim & Effective Floor Protection

SilentCloud 3 mm Acoustic Underlay
SilentCloud 3 mm is a high-performance, low-profile acoustic underlay manufactured from 94% recycled rubber. Despite its slim build, it delivers impact sound insulation of up to 54dB in site testing, outperforming many conventional thin mats.

This underlay is engineered for projects where floor height is critical but acoustic performance cannot be compromised. Designed for use beneath ceramic tile, porcelain, stone, vinyl planks/tiles, LVT, and wood flooring, SilentCloud 3 mm provides both sound reduction and substrate protection, making it ideal for renovations, refurbishments, and new builds with restricted build-up heights.

Key Features & Benefits

Airborne sound insulation up to 50–54dB, exceeding typical thin underlay performance
High-density formulation (~950 kg/m³) delivers more mass than standard 3 mm mats
Weight per m² ~2.9 kg provides superior acoustic control compared with conventional 2.2–2.5 kg/m² products
Slim 3 mm profile, ideal for refurbishments and projects with limited floor height
Moisture, mould, and bacteria resistant for long-term durability
Eco-friendly – made from 94% recycled rubber; contributes to LEED® credits
Durable and load-resistant, suitable for demanding residential and commercial environments
Supplied in 10 m rolls for efficient installation
Fully CE marked and UK Building Regulations Part E compliant

Installation & ordering

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

Need help with installation or choosing the right length? Our technical team can advise on sub‑floor preparation and acoustic performance. We offer free UK shipping from our local warehouse and trade discounts for larger orders.
