The Fono acoustic doors are the most reliable answer to the needs of the soundproofing of studios, classrooms and conference rooms. A double layer of plasterboard and plywood or MDF has the aim to increase the elasticity of the inner layers, while the fiberglass dissipates sound. The door is counter-plated in laminate, veneer or pantographed and is provided with perimeter silicone gaskets and a lower adjustable threshold. The Fono acoustic doors can be solid or with porthole, with handle or panic bar and ensure a sound insulation certificated up to 41.8 dB.
