oundproof RainGuard Tiles

Soundproof RainGuard tiles utilize Helmholtz resonator cavities beneath stone layers, absorbing 30-500Hz frequency rain noise (tested per ISO 10140-2). The viscoelastic adhesive layer dissipates impact energy, achieving 25 dB sound transmission – critical for recording studios. Granule density is optimized at 2.8g/cm³ to block hail noise (UL 2218 Class 4). Non-porous surface inhibits algae growth in rainforest zones.

Installation requires decoupled clips and mineral wool underlay (30mm thickness). Our factory’s acoustic lab provides site-specific noise reduction reports. Case study: A Singapore airport hotel reduced guest complaints by 90% post-retrofit.
