Head and shoulders above the rest, Gyprock Supaceil sets the standard for plasterboard in ceilings. This lightweight 10mm thick plasterboard features Optimised Core technology to provide significantly improved strength, handling and board performance.

Typical Applications

Gyprock Supaceil is typically used as a superior ceiling lining option in residential applications and can be used to span up to 600mm joist centres. It is most suitable for areas of the home where exposure to moisture is not a concern such as bedrooms, living areas and entranceways.

Gyprock Supaceil was the first product in Australia manufactured with Optimised Core technology which provides an advanced performance-to-weight ratio, meaning greater breaking strength in a substantially lighter board that continues to exceed the performance requirements of Australian Standard AS/NZS 2588. This improved strength ensures it will stay flatter, even when installed on ceiling joists with 600mm centres. There is also less chance of fixings pulling through the board when extra pressure from above is applied such as heavy ceiling insulation.

The board’s thicker face paper produces a crisper score and snap experience with cleaner cuts and squarer edges.

Optimised Core™ technology

Plasterboard manufactured with Optimised Core technology has an advanced performance-to-weight ratio, meaning greater breaking strength in a substantially lighter board.

Stronger – more robust with better breaking strength for improved handling and installed performance
Lighter – easier to lift for better sheet manoeuvrability and improved flex
Significantly improved score and snap – for crisp edges and cleaner cuts
