Rigitone Astral
Perforated Plasterboard

Modern seamless design, enhanced acoustic performance and improved air quality thanks to Activ’Air will make Rigitone Astral the star of any project.

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 white acoustic fabric backing which also prevents dust from the ceiling entering the room and masks the ceiling framework.

Rigitone Astral features a regularly staggered pattern consisting of 12mm and 20mm round perforations spaced at 33mm centres, providing a 19.6% 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.

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.

The panels are supplied with a white acoustic fabric backing that improves acoustic performance and eliminates dust from ceiling cavities.

Installation
Rigitone is specially designed to be screw fixed to suspended ceilings. Its unique installation method allows the product’s perforated pattern to continue undisrupted where sheets meet. Unlike the traditional three coat plasterboard jointing systems, Rigitone boards are jointed by directing a specialised compound into a gap between the sheets. The filling method is made possible by the unique Rigitone Filler Accessory Kit, combined with the Rigitone Filler compound. While all four edges of Rigitone sheets are pre-primed, cut edges must be sealed with Rigitone Primer prior to installation, readying the surface for the filler compound.

Activ’Air
Activ’Air is a patented technology that converts formaldehyde into non-harmful inert compounds that are permanently locked in the board and cannot be released back into the air.
