Moisture forgiveness is a building science concept generated by the demand for increased energy efficiency in the built environment. As buildings become increasingly tighter, they also can become more susceptible to moisture damage which can compromise the performance and durability of the building. Building owners, architects, and contractors must employ an integrated project delivery strategy to manage moisture effectively. Georgia-Pacific fiberglass mat gypsum products provide the moisture forgiveness that protects the performance of the structure and the inhabitants within.
