CSR Gyprock has extended its perforated plasterboard range with two new Gyptone profiles for curved ceilings, the Gyptone Flexible 12mm Square and Gyptone Flexible Slotted Minigrid.

Gyptone Flexible perforated plasterboard is installed in one layer and can be dry curved to a radius of 2.2 metres. Gyptone Flexible 12mm Square plasterboard consists of eight large square groupings per sheet, each with 400mm x 12mm square perforations at 25mm centres. Gyptone Flexible Slotted Minigrid plasterboard features eight large square groupings per sheet, each with 16 mini grids of six 6mm x 80mm slot perforations.

Both plasterboard profiles feature black acoustic fabric backing that aims to improve the acoustics of the ceiling. The fabric also aims to eliminate dust from ceiling cavities and mask the ceiling framework so that it’s not seen from below through the perforations.

The Gyptone Flexible range also incorporates Activ’Air technology, which converts formaldehyde into non-harmful inert compounds that are permanently locked in the board and cannot be released back into the air.
