The SilentBoard stands as an unparalleled direct-to-wall soundproofing panel meticulously crafted to amplify the mass of low-density walls. Incredibly efficient on stud walls or low-grade brick walls, it aids in cultivating tranquility within your home environment.

This product ingeniously blends diverse layers of mass into a single, easy-to-install solution, significantly enhancing the ability of low-density structures to resist airborne sound. At a remarkably slim 27mm, the SilentBoard presents an ideal solution when restricted space around door frames or windows restricts the use of other systems.

Key Features:
- System thickness: 27mm
- 4 layers of distinct high-mass soundproofing materials designed to block a broader range of sound frequencies:
1. 15mm Acoustic Plasterboard: Denser and more substantial than standard plasterboard, bolstering wall mass to attenuate airborne noise. Offers the same final finish as standard plasterboard for decoration.
2. 3mm Mass Loaded Vinyl (MLV): High-mass acoustic barrier aiding in blocking airborne noise.
3. 9mm Closed Cell Foam: Dampens sound energy and vibrations.
4. 3mm Mass Loaded Vinyl: A secondary layer of high mass to further impede airborne noise.
