Fire-Rated Systems. construction wood used in the exterior wall must be fire-retardant treated. NA. If the fire resistant material protecting the column is structural, the column specimen must be at least 9 ft (2.7 m) tall, and acceptance is based on its ability to carry an axial load for the duration of the fire test. 4. You might notice the description on the right column noting “UL Des U419.” This is a wall assembly approved by United Laboratories (U.L. 704.1 Requirements. 722.6.2.1 Fire-resistance rating of wood frame assemblies. The fire-resistance ratings of structural members and assemblies shall comply with this section and the requirements for the type of construction as specified in Table 601. This presentation will focus on common detailing issues and areas of misunderstanding—including fire-resistance rating continuity, allowable uses of wood framing in shaft and fire walls, and fire safety principles associated with the intersection of two rated assemblies. Fire remains a concern with timber Fire-Rated Fire-resistance ratings have long been used by UL/ULC, ... E Structural 52-55 Column, beam, through-penetration walls and floors, and joists.

Mid-rise wood-frame 1 layer 2-sided LP FlameBlock 3. NA. ), which has undergone extensive certification and testing to ensure the wall actually prevents fire spread for a minimum of one hour.. 1 Hour Fire Resistant Column Casings. Some wood types, such as heavy timber, have a substantial rating on their own and may result in >1 hr rating with the addition of intumescent paint. Timber provides superior fire protection compared to other wood substrates by forming a substantial char layer once the wood begins to burn. 6 USG Fire-Resistant Assemblies Test Certification Test Conditions and Fire- and sound-tested assemblies listed in this Selector are based on characteristics, properties and performance Certificationof materials and systems obtained under controlled test conditions as set forth in the appropriate ASTM Standard in effect at the time of test.
