Glass Reinforced Gypsum (GRG) panels are advanced building materials consisting of gypsum plaster reinforced with glass fibers, offering exceptional strength, versatility, and lightweight performance. GRG panels are widely chosen for interior decorative features such as ceilings, wall panels, columns, domes, and custom architectural shapes in commercial and residential spaces.
GRG panels are ideal for projects requiring lightweight yet robust materials with high aesthetic flexibility, especially for feature-rich interiors. They are generally used indoors, except for specialized outdoor-grade products.
