Rigitone™ Astral

Technical Specifications Installation Instructions

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 black 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. 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.
