GRG FULLY PERFORATED CEILING TILES
Maximum Acoustic Control with Lightweight Performance
Diamond Ceilings manufactures GRG fully perforated ceiling tiles designed for high acoustic performance in modern architectural interiors. Made from glass reinforced gypsum, these tiles combine engineered perforation patterns and a high-density gypsum core to reduce unwanted noise, improve sound absorption and deliver surface precision across large ceiling grids.
Diamond’s GRG Fully-Perforated Ceiling Tiles are engineered for projects that demand high acoustic absorption (NRC up to ~0.60), and optimised for RH 99 Humidity Resistance. The fully-perforated design enhances noise reduction and ventilation, making it a preferred choice for auditoriums, classrooms, conference halls, and other high-occupancy interiors.

Certifications & Compliance
Diamond GRG Ceiling Tiles are manufactured to meet CPWD specifications and are MES approved.
BIS Certified for quality, fire safety, acoustic control, humidity resistance (RH 99) and structural integrity.
In large and medium-size conference rooms, convention halls, metro stations, commercial buildings, educational institutions and hospitality interiors, managing reverberation is essential.
GRG fully perforated tiles, with certified NRC up to ~0.60, help create acoustic comfort by diffusing sound energy and lowering echo, improving speech clarity and interior user experience.
When paired with a glass fiber membrane, the system achieves elevated sound absorption values suitable for auditoriums, public buildings, airport lounges and open-plan offices.
Bold Feature: These panels are engineered for offering sound reduction solutions in projects where noise control is critical.
Our products are produced from high density gypsum cement reinforced using alkali-resistant glass fiber.
This combination ensures:
• High structural stability
• Crack resistance
• Dimensional accuracy
• Long mechanical life
The gypsum board composition and water-reinforced fiber matrix eliminate deformation, ensuring precise surface lines and excellent surface flatness across suspended grids.
GRG tiles are compliant with globally recognised standards including BS 476, ensuring safe application in airports, hospitals, retail malls, auditoriums and public gathering spaces. Unlike polymer-based ceiling panels, GRG does not release smoke or toxic fumes, making it suitable for institutional buildings and high-occupancy interiors.
Bold Feature: Non-combustible & certified fire resistance rating for public safety.
These tiles maintain excellent surface stability with certified humidity resistance. Even under climate fluctuations, the material avoids moisture swelling, bending or surface inconsistency.
This makes GRG a preferred choice in:
• Coastal cities
• Air-conditioned interiors
• High footfall public spaces
• Transit terminals
The gypsum board composition and water-reinforced fiber matrix eliminate deformation, ensuring precise surface lines and excellent surface flatness across suspended grids.
GRG fully perforated tiles are commonly installed in:
• Convention halls
• Airports & metro stations
• Conference rooms
• Museums and auditoriums
• Waiting rooms & reception areas
• Government and corporate buildings
Architects and designers specify these panels as an effective acoustic medium, ideal for achieving modern false ceiling design visions.
Tiles integrate with standard GI suspension grids including Diamond Ceilings T-Grid suspensions system, providing rapid installation and precise ceiling alignment.
Typical sizes include 595mm x 595mm, but custom dimensions and traditional plaster castings are available for project-specific requirements.
Bold Feature: Lightweight yet strong product, easy to handle during site installation.
The surface finish enhances light reflectance (0.94 Certified), distributing both natural and artificial light uniformly. This contributes to energy-efficient interiors and reduced artificial lighting costs.
The perforated finish supports both contemporary and traditional architectural forms, including linear grooves, geometric layouts and circular apertures.
The tiles are low maintenance, requiring only periodic dusting or limited cleaning. They are also re-paintable, allowing interior designers to change colour schemes without removing ceiling grids.
Benefits include:
• No yellowing
• No surface powdering
• No moisture stains
• Long lasting performance
GRG is a green product, produced with natural gypsum powder and no volatile compounds. It allows re-introduction of heritage detailing without environmental impact. Its composition aligns with modern sustainable construction requirements and regular building trades for public infrastructure.
