What are the weight differences between aluminum and gypsum ceilings?

The weight differences between aluminum and gypsum ceilings are significant. Aluminum is known for its low density, making it one of the lightest structural metals. A complete aluminum ceiling system, including panels and suspension system, weighs approximately 2 to 4 kilograms per square meter, depending on the panel thickness and design. In contrast, gypsum is a much heavier material. A gypsum ceiling system, consisting of gypsum panels, a supporting metal structure, putty, and paint, weighs between 12 to 15 kilograms per square meter, three to five times the weight of an aluminum ceiling. This significant weight difference has significant implications; aluminum's low weight significantly reduces the "dead load" on the building's structural frame, potentially reducing the costs of constructing the primary structure. It also facilitates transportation, handling, and on-site installation, speeding up workflow and reducing labor requirements. This light weight also makes aluminum an ideal solution for renovation projects, as it can be installed over existing ceilings without adding a significant structural load.
