Application | Application 1: Doubling of lumber roof rafters, roof joists and ceiling

Intent | Intent 1: To limit the probability of inadequate strength or stiffness,
which could lead to an inability to resist expected gravity or wind loads
transferred to framing around openings, which could lead to the excessive
deflection or failure of roofs. Where assemblies are required
to provide fire resistance, this is to limit the probability of compromised
fire resistance of the assembly, which could lead to harm to persons.
