Diamond Ceilings supplies GRG ceiling tiles engineered for precision, strength and long-term performance in commercial, residential and institutional buildings. These glass reinforced gypsum ceiling panels are moulded from high-density gypsum cement combined with a glass fiber membrane, resulting in excellent surface flatness, dimensional stability and non-combustible performance.
Ideal for architects and designers seeking clean aesthetics, GRG ceiling systems support traditional architectural shapes, exciting dimensions and modern false ceiling design visions. The tiles integrate seamlessly with standard GI suspension grids for a rigid and accurate installation.
GRG ceiling tiles are manufactured from high-density gypsum cement reinforced with alkali resistant glass fiber. This combination provides:
- Fire resistance and certified humidity resistance
- Light reflectance for improved visual comfort and energy efficiency
- Heat insulation and sound absorbing performance
- Low maintenance and limited cleaning requirements
- A smooth face side suitable for re-paintable finishes
As a non-combustible material, GRG supports specification in hospitals, airports, corporate offices and public buildings with strict fire-safety requirements. The material is free from moisture content issues and maintains stability even in conference rooms, waiting rooms and residential rooms with air-conditioning.
Diamond Ceilings manufactures GRG panels in plain, semi-perforated and fully perforated formats. Perforated patterns allow enhanced acoustic control and reduced unwanted noise in large interior spaces such as convention halls and corporate meeting rooms. Clients may choose from decorative plaster castings, traditional architectural forms or custom linear patterns based on project requirements.
Our production capability supports re-introduction of heritage designs, curved applications, seamless junctions and bespoke architectural forms for luxury interiors.
GRG ceiling tiles are installed using lay-in grid systems or concealed suspension where a monolithic appearance is desired. They are commonly used in:
- Corporate offices and boardrooms
- Educational institutions and libraries
- Retail interiors and hospitality areas
- Airports, hospitals and institutional buildings
- Residential living rooms and premium home theatres
The tiles offer a lightweight and strong product profile, ensuring ease of handling during installation. Re-paintable surfaces allow architects to apply colour schemes without surface distortion.
