Dividing buildings into distinct fire-protected
areas is typically accomplished by providing fireresistance
rated separations between those
areas. This type of separation is easily achieved
by the use of gypsum board applied to either
wood or steel framing members. These fire-rated
separations are usually provided as total
assemblies, consisting of the structural member,
the gypsum board and structural flooring material
(if a floor/ceiling assembly). Listings of many firerated
assemblies or Designs are found in the GA-
600, UL Fire Resistance Directory, etc.
