Product Overview

Manufactured by worldwide plasterboard specialist, Saint-Gobain, Protone 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 white acoustic fabric backing which also prevents dust from the ceiling entering the room and masks the ceiling framework.

Protone Slotted Minigrid features eight large square groupings per sheet, each with 16 mini grids of six 6mm x 80mm slot perforations. This contemporary design provides 13% open area

Protone is also manufactured with Activ’Air technology which has an enduring impact on indoor air quality.  All four edges of Protone 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.

This includes applications such as theatres, restaurants, shopping centres and hotel foyers. Whilst perforated plasterboard in predominantly installed in ceilings, it is suitable for use in walls.

Protone joints are finished with a three coat jointing system and sanded smooth prior to decoration.
