GRG Semi-Perforated Ceiling Tiles

In interior spaces such as conference rooms, convention halls, waiting rooms, residential rooms, and institutional buildings, unwanted noise affects comfort and speech clarity. GRG semi-perforated tiles are designed to be sound absorbing, reducing reverberation and improving acoustic balance. When paired with approved glass fiber membrane backing, the system achieves targeted NRC ratings suitable for auditoriums, airports and healthcare facilities.

GRG is a naturally non-combustible, fire resisting, and fire retarding material. Diamond Celings tiles comply with international standards including BS 476, ensuring flame spread and smoke development values suitable for public buildings. These tiles are specified for lobbies, corridors, transit terminals and any area requiring fire resistance with architectural detailing.

Humidity changes often cause deformation in traditional false ceiling materials. Diamond GRG ceiling tiles maintain dimensional accuracy and excellent surface flatness, even in humid coastal environments. The formulation—using gypsum powder and glass fiber membrane resulting in high density—delivers certified humidity resistance, making the system suitable for airports, hotels, malls and large commercial buildings.

Semi-perforated tiles are regularly installed in:

• Convention halls
• Conference rooms
• Institutional buildings
• Corporate offices
• Reception and waiting rooms
• Retail malls and atriums
• Theatres and auditoriums

Architects select these tiles to achieve modern interior spaces, better light reflectance, clean detailing and long-term performance without surface cracks or deformation.

The surface of the tile is engineered for better light reflectance, balancing natural and artificial lighting. Unlike mineral fiber ceilings, GRG provides a more seamless, monolithic look with no visible joints after finishing. Decorative traditional architectural forms or contemporary linear patterns can also be integrated.

GRG tiles arrive factory-finished and ready for coating. The material is re-paintable, requires limited cleaning, and offers low maintenance throughout its lifecycle. The non-porous composition prevents dust collection and ensures long-term aesthetic performance without yellowing.

Tiles are compatible with standard GI suspension grids and false ceiling frameworks. The material allows fast cutting and edge detailing on site. Its lightweight and strong product properties reduce load on structure, while offering the precision required for concealed grid systems.

Where higher acoustic absorption is required, fully perforated ceiling tiles are recommended. Semi-perforated tiles remain the ideal balance between design versatility, sound absorption and structural stability. Both solutions are manufactured in-house under strict quality and dimensional control.

GRG is a green product, manufactured from natural gypsum powder with no VOCs, asbestos or harmful additives. It supports sustainable construction practices and is widely accepted by architects and designers for modern public infrastructure.
