`The use of fire separation walls in structures , such as in 20
`FIG . 9 is a perspective of a wall having fire retardant
`multifamily housing , is commonplace . Often , fire separation
`sheathing with a slot cut in the sheathing to receive the truss
`is required to be continuous along the walls between adjoin

`ing units to prevent fire from spreading between the adjoin -
`FIG . 10 is the perspective of FIG . 9 , but showing two of
`ing units in a multifamily structure . For some types of
`construction , the building codes also require exterior walls 25 the truss hangers mounted thereon ;
`to be fire rated . Typically , gypsum board is used as a fire
