There are several types of sheathing, each having a specific function based on its application. Advantages of noncombustible construction Easy to erect Economical to build Uses materials that do not readily burn Disadvantages of noncombustible construction Contains steel, which loses strength at high temperatures Highly damageable buildings Unstable buildings under fire conditions Uses slow-burning materials that do burnadding fuel to a fire However, the term 'wall' is not defined in the BCA. The IMC is the only code that defines noncombustible. : 3. Signs may be provided, as determined by the enforcing agency prohibiting any use underneath including storage. The National Building Code of Canada (NBCC) defines a firewall as a fire separation that subdivides or separates adjoining buildings; such fire separations restrict fire to a prescribed degree and most importantly, have structural stability under fire conditions. A key advantage of using ICFs is faster installation times, which you can achieve when the floor-to-ceiling height stays the same on each in a multi-storey building. The roof is also of non-combustible material, such as concrete or steel. The ''B'' designation means that no fire resistance rating is required (referred to as ''unprotected'' wood frame construction). Neither the exterior nor interior walls need to be of noncombustible materials, though some areas must be rated for . Noncombustible or slow-burning floors and roofsregardless of the type of insulation on the roof surface Advantages of masonry noncombustible construction Uses floors and roof supported by superior exterior bearing members that provide for stability and are less likely to collapse during a fire Uses materials that do not readily burn Definition.
