Features of the soundproofed enclosures
The Fonois acoustic enclosures are constructed with a robust, hot-welded galvanised steel load-bearing frame, ensuring excellent structural integrity and long-term durability.
Modular sheet metal panels are internally treated with a multilayer system of sound-insulating, damping, and vibration-absorbing materials to maximise acoustic performance.
The panel surface facing the noise source incorporates a sound-absorbing mat made from non-toxic natural textile fibres, bonded with fire-retardant phenolic resin and protected by a black nonwoven polyester layer (TNT). This configuration leaves 100% of the absorbent surface exposed, ensuring optimal sound absorption and compliance with fire safety and environmental standards.
Thanks to their compact configuration and optimised materials, Fonois soundproofed enclosures offer up to 50% footprint reduction compared to conventional acoustic solutions with equivalent performance. Enclosure components are removable and versatile, featuring high-performance multilayer cladding engineered to deliver excellent sound insulation and absorption. They are suitable for containing noise sources in both indoor production areas and outdoor environments. For applications where partial shielding is sufficient, such as HVAC systems or refrigeration units, Fonois also provides sound barrier solutions, including Quiet Leaf™ noise barriers.
