Flame Spread - CWC - The Canadian Wood CouncilSimilarly, if no ceiling is installed beneath a floor or roof assembly, the unfinished exposed deck and structural members are considered to be the interior ceiling finish. ... For instance, lumber, regardless of species, and Douglas fir, poplar, and spruce plywood, of a thickness not less than those listed, are assigned a flame-spread rating of 150. ... Most surface coatings such as paint and wallpaper are usually less than 1 mm thick and will not contribute significantly to the overall rating.

Calculating Fire Resistance Ratings of Wood Assemblies Using the ...20 Feb 2009 ... The section details the procedures for calculating fire resistance of walls, floor/ceiling and roof/ceiling assemblies. The total fire rating is determined by adding each component to reach a minimum total of 60 minutes. Fire protection rating is calculated from the flame side of the assembly and of course some assemblies have multiple flame sides. Your wood framing members are required to be not more than 16 on center. When they are you get 20 minutes in a wall ...

A non- combustible Material - NCDOI8 Sep 2011 ... Chapter 6 of the North Carolina Building Code (NCBC) classifies buildings on the basis of the combustibility of the materials from which they are constructed. Classifications by materials are referred to as the Type of Construction of the building. Types I and II construction by definition require all structural (load-bearing) frame members to be non-.

Wood in Noncombustible Bldgs - CWCIn certain cases, ordinary wood finishes (a FSR of 150 or less) can also be used on 10% of the ceiling area of any one fire compartment, as well as on the ceilings of exits, lobbies and corridors. Fire-retardant-treated wood (FRTW) must be used to meet the most restrictive limit of FSR 25. Consequently, it is permitted extensively throughout noncombustible buildings as a finish. The only restriction is that it cannot exceed 25 mm in thickness when used as a finish except when used as ...
