Glass fiber reinforced gypsum board (GFRG) is a composite material consisting of alpha gypsum cement and water, reinforced with glass fibers, ideal for an economical, lightweight and durable alternative to traditional gypsum.
Glass fiber reinforced gypsum board (GFRG) is a construction panel product made from calcined gypsum, plaster. Produced under strictly controlled conditions, the panels are 124 mm thick, 12 m long and 3 m high, contain cavities and can be unfilled, partially filled or fully filled with reinforced concrete, depending on structural requirements. Experiments and studies in Australia, China and India have shown that GFRG panels, properly filled with plain reinforced concrete, have considerable strength and can be used not only as load-bearing elements but also as shear walls, capable of resisting lateral loads caused by earthquakes and wind.GFRG panels can also be used as infill (non-load-bearing) in combination with columns and beams of RCC frames (conventional frame construction for multi-story buildings). There is no restriction on the number of storeys, and the micro-beams and RCC mortar (acting on T-beams) can be used as floor/roof slabs.
1. Strength: GFRG board is stronger than regular gypsum board and can withstand higher loads.
2. Fire Resistance: GFRG board has excellent fire resistance properties and can withstand high temperatures without losing its strength.
3. Durability: GFRG board is highly durable and has a longer lifespan compared to regular gypsum board.
4. Lightweight: GFRG board is lightweight and easy to install, making it a popular choice for construction projects.
5. Moisture Resistance: GFRG board is highly resistant to moisture and can be used in areas with high humidity levels, such as bathrooms and kitchens.
6. Malleability: GFRG board is highly malleable and can be easily molded into various shapes and designs.
