Exploring the Origins of GRC Jali: A Historical Perspective
A new material concept was introduced in 1976 in Europe and the United States, a product now known as GRC – Glass Fiber Reinforced Concrete.
It is not a single material but a family of high-performance cement-based composites reinforced with special alkali-resistance glass fibers, which can be engineered for various applications.
The glass fibers in this composite increase the tension and impact strength of the material.
GRC Jali is an architectural screen made from glass fiber reinforced concrete (GFRC), a composite material of cement, fine aggregates, water, chemical additives, and alkaline-resistant glass fibers.
It is famous for its low energy consumption, natural raw materials, and versatility in design and shape.
GFRC Jali originates from the traditional Jaali, a window or screen mesh carved into wood or stone by artisans. Jaali was commonly found in Islamic and East Asian architecture, and it was initially developed as an architectural solution for combatting extreme heat in arid climates and regulating light. The best use of GRC Jali in India are: aesthetic and cultural functions, such as creating intricate patterns of light and shadow, providing privacy and ventilation, and expressing religious and artistic motifs.
GRC Jaali is a modern adaptation of the ancient Jaali, using GFRC as the material instead of wood or stone. It can be used for various purposes, such as facade, partition, skylight, door panel, railing, and more. GRC Jali can also be customized according to the client’s needs and requirements, and it can vary in size, shape, color, and pattern.
