A gypsum board false ceiling is a popular suspended ceiling system consisting of lightweight factory-made gypsum plasterboards fixed to a galvanized iron or aluminum framework, suspended from the main ceiling. It provides a smooth, aesthetic, fire-resistant, and thermally insulated finish, ideal for hiding wiring, pipes, and installing lighting in residential and commercial spaces.
Key Components and Specifications
- Gypsum Boards: Typically available in thicknesses of 9 mm, 12.5 mm, and 15 mm, with standard sizes like 1200 mm x 2400 mm. Specialized boards include moisture-resistant (for kitchens/bathrooms) and fire-resistant options.
- Metal Framework: Comprises perimeter channels (secured to walls), primary channels, and secondary ceiling sections that create a sturdy grid to support the boards.
- Jointing and Finishing: Joints between boards are covered with paper tape and three coats of jointing compound, then sanded for a seamless, smooth finish before painting.
