In the comparison of tiles and glass, tiles are generally heavier. This is due to the composition and density of both materials. Tiles are typically made from ceramic, porcelain, or stone, which are heavier and denser than glass. For instance, ceramic tiles can weigh anywhere from 1 to 2 pounds per square foot, while glass, especially float glass commonly used in windows and doors, weighs approximately 0.8 pounds per square foot. This difference in weight is attributed to the materials' density and the manufacturing processes involved. Tiles are often thicker and have a higher mass per unit area, making them heavier than glass.
