Description
SilentCloud™ MassDeck 33 is a high-performance acoustic floating floor system specifically engineered for lightweight construction types such as timber frame, where controlling both impact (footfall) and airborne sound is critical to meeting UK Building Regulations.
Manufactured using a cement particle chipboard, eco-friendly acoustic felt, and a rubber barrier mat, MassDeck 33 delivers an effective balance of mass, resilience, and acoustic isolation, allowing it to achieve robust, repeatable soundproofing performance in applications where lighter systems are often insufficient.
Designed for new build, change of use, and refurbishment projects, SilentCloud™ MassDeck 33 provides the acoustic performance of traditional screed systems in a dry, time-efficient installation, eliminating curing delays and reducing site complexity.
