Glass Fiber Reinforced Gypsum (GRG)

Glass Fiber Reinforced Gypsum (GRG) is a composite material made from high-strength resistant glass fibers bonded with high-density gypsum cement. It serves as an advanced alternative to traditional plaster castings, offering improved strength, lighter weight, and ease of installation. GRG is widely used for creating unique architectural designs, both modern and traditional, such as curved and organic shapes on walls and ceilings. It has become a preferred choice for designers and architects due to its versatility and ability to meet various design requirements.

Key Features of GRG:

• Lightweight & Strong: GRG panels are lighter and stronger than traditional plaster castings, making them easier to handle and install.
• Design Versatility: Ideal for creating complex shapes and curves in drywall or plasterboard applications. It enables intricate designs like perforated and semi-perforated ceiling tiles.
• Moisture Resistant: With a moisture content of less than 2%, GRG is highly resistant to humidity, making it suitable for diverse environments.
• Non-Combustible: GRG conforms to fire safety standards, being classified as non-combustible as per BS 476 (Part 4, 1970).
• Acoustic Performance: It offers sound absorption with a Noise Reduction Coefficient (NRC) ranging from 0.50 to 0.75, ensuring good acoustic properties.
• Reflectivity: GRG has a high light reflectance value of 85% (minimum), enhancing the interior illumination.

GRG Ceiling Tile Specifications:

• Tile Dimensions: Standard size of 595×595 mm.
• Tile Thickness: Available in semi-perforated (12 mm thick) and fully perforated (10-12 mm thick) micro tegular or square-edged tiles.
• Humidity Resistance: 99%, making them ideal for use in areas with high moisture.

Installation Details:

• Suspended False Ceiling System: GRG tiles are installed using a T-Grid system made from hot-dipped galvanized iron sections. The grid modules are sized 600×600 mm, with the main T-runners and cross-T sections forming the framework.
• Galvanized Mild Steel Components: Components such as hanger rods, fasteners, and perimeter wall angles are used to suspend and fix the ceiling system, ensuring a sturdy installation.

Applications:

• Architectural Forms: GRG is used in creating both modern, organic shapes and traditional architectural elements.
• Raw Industrial Look: Designers often opt for GRG in combination with metal mesh ceilings to achieve an industrial aesthetic.

GRG’s ability to combine design flexibility with functionality makes it an excellent material for ceilings in offices, auditoriums, and commercial spaces.
