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.
