PVC board is generally lighter than glass. The density of PVC board is typically around 1.4 grams per cubic centimeter (g/cm³), whereas glass has a density of approximately 2.5 g/cm³. This difference in density directly translates to a difference in weight. For instance, a 1-meter cube of PVC board would weigh approximately 1.4 kilograms, while the same volume of glass would weigh around 2.5 kilograms. This information is based on standard material properties for these two materials. The lighter weight of PVC board makes it more suitable for applications where weight is a concern, such as in the construction of lightweight panels or in the manufacturing of certain types of furniture.
