Abstract: Interest in using engineered wood products in Type III construction in the United States has been rising in recent years. The wood industry has been heavily engaged in the promotion of multifamily and light commercial construction in which wood-frame Type III construction predominates. Type III construction, based on the definition of the International Building Code (IBC) is “that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of any material permitted by this code,” except that fire-retardant-treated (FRT) wood framing complying with the IBC is permitted within exterior wall assemblies of a 2-hour rating or less.

Keywords: Fire retardant; structural glued laminated timber; laminated veneer lumber; treatment effect; hygrothermal effect
