SilentSand Acoustic Board — High-Density Sand-Filled Soundproofing Panel
SilentSand Acoustic Board is a premium sand-filled acoustic panel designed to drastically reduce noise in residential, commercial and studio environments. Engineered to add exceptional mass and vibration damping in a slim profile, SilentSand is ideal for soundproofing walls, ceilings and floors where space is limited.
What Is SilentSand Acoustic Board?
SilentSand is a 15mm acoustic board filled with compacted sand granules. These granules move microscopically when sound energy hits the panel, converting sound energy into heat through friction. This internal damping makes SilentSand extremely effective at stopping airborne noise such as talking, TV, traffic noise and low-frequency rumble.
Key Features of SilentSand
- Ultra-dense 15mm panel adding significant mass
- High airborne noise reduction
- Excellent internal damping for low-frequency control
- Simple retrofit installation
- Compatible with plasterboard, flooring systems, and suspended ceilings
- Clean, non-fibrous, dust-free panel
Typical Dimensions & Mass
| Specification | Detail |
|---|---|

SilentSand’s biggest advantage is its high mass in a small thickness, allowing serious sound reduction without losing significant room space.
Acoustic Performance
SilentSand delivers strong airborne noise reduction and supports impact noise improvement when used in a complete flooring system.
Airborne Noise
