Deliver an aesthetic impact and significantly improve acoustics with Rigitone Matrix 8mm Round. The edge-to-edge pattern layout, unique installation method and benefits of Activ'Air make Rigitone a superior option.

Product Overview

Manufactured by worldwide plasterboard specialist, Saint-Gobain, Rigitone is purpose built to provide exceptional acoustic control with ultimate 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. 

Rigitone Matrix 8mm Round provides a pattern of 8mm round perforations at 18mm centres, providing a 15.5% open area.

Rigitone is also manufactured with Activ’Air technology which has an enduring impact on indoor air quality. The edges of Rigitone boards are square cut and pre-primed for a unique installation method using ready-mixed Rigitone Filler, creating a continuous, seamless finish. The availability of seamless access panels, ensures easy access to the ceiling cavity while maintaining pattern continuity.

Typical Applications:

Rigitone perforated plasterboard is typically used as a high performance plasterboard for ceilings in commercial constructions where a high level of acoustic performance is required. 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.

The unique installation method allows the product’s perforated pattern to continue uninterrupted, achieved using a specialised compound, accessory kit and primer prior, readying the surface for sanding and painting.

Access Panels

Rigitone Access Panels are integrated into suspended ceilings to allow for inspection, service and maintenance work on the installations in the space above. Gyprock offers an access panel solution for the Rigitone range that provides easy access and integrates seamlessly into the ceiling.
