What is both flexible and rigid? Linear and curvilinear? Conventional and innovative? It’s gypsum wallboard. Long recognized as one of the construction industry’s most affordable and versatile building materials, it is the contractor’s staple, the designer’s canvas and the architect’s clay. It becomes the walls around us and the ceilings above us. Protecting us from sound and fire while providing our building interiors with beauty, structural integrity and safety. When you think about it, gypsum wallboard is one very amazingly simple and humble product.
