About the Technology

Glass Fibre Reinforced Gypsum (GFRG) Panel also known as Rapidwall is made-up of calcined gypsum plaster, reinforced with glass fibers. The panel was originally developed by GFRG Building System Australia and used since 1990 in Australia for mass scale building construction. In recent times, these panels are being produced in India and the technology is being used in India.

GFRG is an integrated composite building system using factory made prefab load bearing cage panels and monolithic cast in-situ RC infilled for walling and floor/roof slabs, suitable for single storey to ten storey building. It is made of calcined gypsum plaster, reinforced with glass fibres and panels manufactured to a thickness of 124mm under carefully controlled conditions to a length of 12m and height of 3m, containing cavities. The cavities are filled with reinforced concrete or any other filler material as per design requirements. The panel are being produced at FRBL Kochi and RCF Mumbai and being promoted by IIT Madras.
