What Is Gypsum Board Made of?

Gypsum board is a product that is commonly used in the building industry today. It can be made out of several different types of materials. Most commonly, it is made by pressing gypsum plaster together very tightly between two very thick sheets of paper. In some cases, manufacturers will use fiberglass instead of paper to create a harder surface that is mold resistant. When this product is created, it produces a very hard surface that can easily be cut to fit in any construction project. This material is used when creating walls and ceilings.
