3mm Premium Acoustic Underlayment — 94% Recycled Rubber, Up to 54 dB 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 54 dB 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.
