The hollow sections can accommodate building services such as plumbing and electrical conduits.

Rapidwall is a load bearing building panel with a multitude of uses for the construction industry.

It is ideal for just about any construction in which current building practices are used and is suitable for single, double or multi-storey housing and for commercial and industrial development.

Rapidwall eliminates the need for bricks, timber wall frames and plasterboard as it serves as both the internal and external load bearing wall.

Because of its low energy and environmental credentials, Rapidwall is particularly suitable in areas where traditional building materials, that have high energy usage, high carbon emissions or cause degradation to the environment, are no longer sustainable.

Rapidwall panels are manufactured, in moulding process, from high grade gypsum plaster and glass-fibre rovings to a size of 12 metres by 3 metres by 123 millimetres thick. The hollow sections, or voids, have 250 millimetre centres.

The panels are cut in the factory to design specifications to a maximum tolerance of 5 millimetres.

After cutting, the panels are loaded onto collapsible frames called stillages ready for transport to the building site. Up to 500 m² of Rapidwall can be transported on one truck.

The panels are lowered into position using a small crane and supported by props until the structure is completed.

The formed cells can be filled with insulation for increased thermal performance or with concrete for increased load-bearing structural capacity.
