T-bar ceiling tiles come in various materials, including mineral fiber, fiberglass, metal, and PVC. Each material has its own set of characteristics that cater to different needs. Mineral fiber tiles, for instance, are known for their acoustic insulation properties, making them ideal for spaces that require sound management, such as offices and schools. Metal tiles, on the other hand, offer a sleek, contemporary look, while PVC tiles are highly durable and moisture-resistant, suitable for environments like kitchens and bathrooms.
