Manufactured by worldwide plasterboard specialist, Saint-Gobain, Gyptone is purpose built to provide exceptional acoustic control with contemporary design. A flexible option provides even greater levels of design freedom. High levels of acoustic absorption are achieved through a combination of perforation patterns and a highly effective black acoustic fabric backing which also prevents dust from the ceiling entering the room and masks the ceiling framework. Gyptone 12mm Square features eight large square groupings per sheet, each with 400 x 12mm square perforations at 25mm centres, providing a 16% open area. Gyptone is also manufactured with ActivAir technology which has an enduring impact on indoor air quality. All four edges of Gyptone perforated plasterboards are recessed to make flush jointing quicker and easier without the need for butt joints between full panels. The availability of seamless access panels, ensures easy access to the ceiling cavity while maintaining pattern continuity.
