A non- combustible Material - NCDOI

8 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-.

Flame Spread - CWC - The Canadian Wood Council

Similarly, 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. 【Get Price】

Fire Resistance - CWC - The Canadian Wood Council

Horizontal assemblies such as floors, ceilings and roofs are tested for fire exposure from the underside only. This is because a fire in Most steel-stud wall assemblies are tested and listed as non-loadbearing because they are used primarily in non-loadbearing applications in noncombustible buildings. . NBCC, Division B, Appendix D also includes empirical equations for calculating the fire-resistance rating of glue-laminated (glulam) timber beams and columns, in Appendix D-2.11. 【Get Price】

Wood in Noncombustible Bldgs - CWC

In 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  【Get Price】

Fire Resistive Design in Timber Structures - Western Wood Structures

Heated steel tends to expand and loses a significant portion of its stiffness, causing steel columns and beams to collapse, even though steel is often defined as non-combustible. This can result in damage to other There are many types of wall, floor, floor-ceiling and roof-ceiling assemblies available for use. For purposes of this satisfactory performance. The newer method, One-Hour Fire-Resistive Construction, is based on calculating the capacity of timber members exposed to fire. 【Get Price】
