Abstract. The National Building Code of Canada provides both prescriptive specifications for timber beams and columns afforded equivalency to wood-frame construction with 45 min fire-resistance ratings, and simple calculation methods for determining fire-resistance ratings of larger glued-laminated

While most decking woods are naturally beautiful, and highly resistant to decay, there is one on the market that is praised for its ability to resist fire and its ability to last. AmeraDeck decking wood is a Grade A decking material mostly known for its uncanny ability to resist fire. In fact it has a Class A- fire rating, the highest rating 

construction and the degree of fire resistance of the primary structural framing material. The NFPA classification system designates the five types of construction using Roman numerals (I, II, III, etc.) followed by three Arabic numbers (332, 211, etc.) that indicate the hourly fire-resistance rating requirement for specific structural
