Gyprock Aquacheck moisture resistant plasterboard

Gyprock Aquacheksuptrade

Gyprock Aquachek's core, face and back are treated to make it resistant to moisture and humidity without compromising integrity. It is specifically designed for use as a lining in wet areas of residential or commercial buildings.

Because Aquachek is not subject to moisture movement and has extremely low water absorption characteristics, it provides an excellent, stable substrate for ceramic tiles.

Gyprock manufactures other plasterboards with moisture resistant properties that may satisfy a wider range of performance requirements:

Gyprock Aquachek is manufactured in Australia to Australian Standard AS2588 and the heavy-duty face paper is a blue colour.​​​​​​

Product Options

Gyprock Aquachek is available in 10mm and 13mm thicknesses and in 1200mm and 1350mm widths. The long edges are recessed for flush jointing.

In a horizontal setout, the 1200mm sheet width suits standard 2400mm ceiling heights and 1350mm suits 2700mm ceilings. In commercial applications, plasterboard is often installed vertically to cater for higher ceilings.
