The heavier timber effectively creates resistance to fire. Type III Construction: Ordinary. Type III: Exterior walls and structural elements are noncombustible or limited-combustible materials, and interior structural elements, walls, arches, floors, and roofs are wood that is smaller than what is required for Type IV construction. Type V construction requires other alternatives, including, but not limited to, positive pressure attacks. How building class is determined: All buildings must be classified into one of six construction classes (see number 3). Type 4 buildings are excluded because of their old age and more uniform design.
