Demystifying Fire-Retardant-Treated Wood Specifications

Writing a strong, generic specification for Fire-Retardant-Treated Wood helps ensure code-compliant FRTW will be installed, competition will be encouraged, and ultimately performance and value for the owner will be delivered. This article, which appeared in the December 2021 issue of The Construction Specifier, contains a strong, generic model specification in standard CSI format for Fire-Retardant-Treated Wood. The article helps specifiers:

UL Tests Result in GreenGuard and GreenGuard Gold Certifications for Pyro-Guard®

Certification allows Pyro-Guard users to breathe easier!

PYRO-GUARD® treatment has earned UL’s GREENGUARD and GREENGUARD GOLD Certifications. Recognized and referenced by over 400 codes, rating systems, and procurement policies worldwide, GREENGUARD and GREENGUARD GOLD Certifications require that products meet some of the world's most rigorous and comprehensive limits for low emissions of volatile organic compounds into indoor environments. 

UL Critical Component Identification in Fire Resistance-rated Designs

Have you ever wondered why some items within UL Certification designs have asterisks* following an item’s description? Here's your answer.

UL Certifies NFPA 285 Exterior Wall System with Fire-Retardant-Treated Wood

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.

Can fire retardant coatings be recognized as fire retardant treated wood?

The answer is No according to Code Interpretation 17-005 issued by the California State Fire Marshal.

Best Practice in Fire-Retardant-Treated Wood Code Enforcement

The job of a building code official carries more than its share of accountability. On the one hand, code officials are responsible for the life safety of the occupants of the buildings they inspect. On the other, they face the interests of community leaders, developers, architects, builders, general contractors, building material suppliers, and various other stakeholders looking to advance the building project and the investment it represents.

Fire-Retardant-Treated Wood Must be Impregnated with Chemicals

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 materials or FRTW.

UL Certifies Proprietary Design with Fire-Retardant-Treated Wood

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 the first fire-resistance rated bearing wall assembly to be tested by UL with FRTW. The design calls for the use of Pyro-Guard® FRT lumber and plywood. A product of Hoover Treated Wood Products, Pyro-Guard lumber and plywood is widely used for weather protected applications in buildings of Type I, II, and III construction.

Pyro-Guard's Unique Listing Provides Cost Effective Alternative to Other 2-Hour Assemblies

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 majority of structure exposures providing an alternative to those designers wanting an UL Design number.
