Glass Fiber Reinforced Gypsum (GFRG) Panel is a building panel product, made of calcined gypsum, plaster, reinforced with glass fibers, for Mass-scale building construction, was originally developed and used since 1990 in Australia. The panel, manufactured to a thickness of 124mm under carefully controlled conditions to a length of 12 m and height of 3m, contains cavities that may be unfilled, partially filled or fully filled with reinforced concrete as per structural requirement. Experimental studies and research in Australia, China and India have shown that GFRG panels, suitably filled with plain reinforced concrete possesses substantial strength to act not only as load bearing elements but also as shear wall, capable of resisting lateral loads due to earthquake and wind. GFRG panel can also be used advantageously as in-fills (nonload bearing) in combination with RCC framed columns and beams (conventional framed construction of multi-storey building) without any restriction on number of stories micro-beams and RCC screed (acting on T-beam) can be used as floor/ roof slab.
1. Strength and Durability: GFRG boards are highly durable and have high strength due to the reinforcement provided by glass fibers. This makes them suitable for use in areas where high impact resistance is required.
2. Fire Resistance: GFRG boards are highly fire-resistant and can withstand high temperatures without burning or emitting toxic fumes.
3. Design versatility: GFRG boards can be molded into a variety of shapes and sizes, making them a popular choice for use in interior design applications such as decorative ceiling tiles or wall panels.
4. Eco-friendly: GFRG boards are made from natural materials and are recyclable, which makes them an environmentally friendly choice for construction projects.

GFRG can also be used to create decorative elements such as cornices, moldings, and columns. These elements can be molded into intricate shapes and designs and are often used in high-end residential and commercial projects.
Another application of GFRG is in the manufacturing of large-scale architectural elements such as domes, vaults, and arches. GFRG is an ideal material for these types of structures because it is lightweight, easy to mold, and can be formed into complex shapes.
Finally, GFRG can be used to create prefabricated modular buildings. These buildings are constructed off-site and then transported to their final location, making them an ideal solution for remote or hard-to-reach areas.
Grade and Type- GFRG panel may be supplied in any of the following three grades :
1) Class 1- Water Resistant grade – panels that may be used for external walls, in wet areas and/or as floor and wall formwork for concrete filling; 2) Class 2 – General grade -- panels that may be used structurally or non-structurally in dry areas. These panels are generally unsuitable for use as wall or floor formwork;
3) Class 3 – Partition grade – panels that may only be used as nonstructural internal partition walls in dry areas only.
