Lightweight ceiling panels are primarily manufactured using PVC (Polyvinyl Chloride), Mineral Fiber, Aluminum, or EPS (Expanded Polystyrene). PVC panels are highly favored for their waterproof and anti-corrosive properties, making them ideal for high-humidity areas like bathrooms. Mineral fiber panels offer superior acoustic insulation and fire resistance (Class A), which is essential for office environments. Aluminum honeycomb panels provide the highest strength-to-weight ratio, ensuring long-term structural integrity without sagging.
