The Protone Range features three contemporary perforation patterns with white acoustic fabric backing, Protone 12mm Square, Protone 12mm Square Minigrid, and Protone Slotted Minigrid, each with different percentages of open area to meet most acoustic application requirements. Each board in the range is supplied at a size of 2400mm x 1200mm x 12.5mm. 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. The Protone boards can also be used for curved installations down to a radius of 6000mm (dry bending), allowing architects and designers to create stunning architectural features. Unlike standard plasterboard, all four edges of the Protone sheet are recessed to make flush jointing quicker and easier which negates the need for back blocking on butt joints.
