Dimension lumber is commonly used for Wood-Frame construction in floor, wall, and roof assemblies. Building codes provide guidance on how Wood-Frame construction can be used to meet fire safety requirements. Dimension lumber can of course be used in assemblies which do not require a fire-resistance rating. Where a rating is required, the required level of performance can be met by sheathing the wood framing with materials such as gypsum wallboard to protect the wood and retard the spread of fire. The Fire Safety Design in Buildings book outlines the potential for using dimension lumber for all types of buildings both for structural and decorative purposes while meeting fire safety requirements.
