Gypsum is a naturally fire-resistant material that has become a leading construction component of fire-rated wall assemblies. Interior finishing materials are rated for flammability.



There are several types of fire-resistant wall assemblies to suit project specifics, including loadbearing and non-loadbearing.

Fire-Resistant Products
