Have you ever wondered why some items within UL Certification designs have asterisks* following an item’s description? Here’s your answer. Most UL fire resistance-rated certifications (designs) consist of various specified components constructed in a very specific manner and are considered as a complete assembly. Fire resistance-ratings apply only to assemblies
Hoover leads the way! Again! UL recently tested and promulgated a listing for an exterior wall system (EWS) containing pressure-impregnated fire-retardant-treated wood (FRTW), which makes the plan approval process for Type I, II, and III construction quicker and easier for architects. The new NFPA 285 listing, UL System No. EWS0045,
The answer is No according to Code Interpretation 17-005 issued by the California State Fire Marshal. California State Fire Marshal Code Interpretation 17-005

The 2018 International Building Code clarifies that fire-retardant-treated wood (FRTW) manufactured without using the pressure process must be impregnated with chemicals. New language in the 2018 IBC clarifies for building officials the regulations for using FRTW in Types I, II and III construction, which call for the use of non-combustible
UL recently tested and promulgated a listing for a new two-hour load bearing wood-frame wall assembly containing pressure impregnated fire-retardant-treated wood (FRTW), a move that makes it quicker and easier for building officials to approve plans for Type III construction. The new fire resistive listing, UL Design No. V314, is
FRTW is allowed by UL to be used in any listed wood-frame wall assembly. A recent test at UL has resulted in a unique listing for a 2-hour fire-resistance rated bearing wall assembly of Pyro-Guard fire-retardant-treated lumber and Pyro-Guard fire-retardant-treated plywood. This new listing, UL Design No. V314, covers the vast
The Minnesota Department of Labor and Industry has issued the following publication after recent concerns of non-code compliant fire-retardant-treated wood being used in local construction projects. The publication points out the building code requirements for fire-retardant-treated wood and the importance of labeling for proper product identification. Fire-Retardant-Treated Wood and
