Dec- Hom

The GRG range of ceiling tiles are manufactured from glass reinforced gypsum and comprise non-combustible gypsum casting plaster reinforced with a glass fiber membrane resulting in a light weight, strong and prestressed panel.

Fire Performance: Non-combustibility: GRG tiles are rated non-combustible as defined in BS 476: Part-4, 1970. Surface Spread of Flame: GRG tiles are rated Class 1 for surface spread of flame to BS 476: Part-7, 1987. Fire Propagation: Test results to BS 476: Par-6, 1989 indicate a Class O surface. Smoke and Toxic Fume Emission: The tiles are zero rated for smoke emission. No toxic fumes are given off.

Humidity Resistance: The tiles have excellent moisture resistance and can be used in areas of high humidity including covered external areas, kitchens and bathrooms. Tested in an atmosphere of 95% R.H. at 12°C for 14 days, the tiles did not sag or distort and showed only a minimal increase in weight. Unlike most other ceiling materials, this important attribute can often be used to speed up the building program by installing the ceiling before the building is fully weather tight.
