Finished flooring includes products such as wood strip flooring, engineered (laminate) flooring, resilient flooring, ceramic tile and carpet. The two essential properties of finished flooring are durability and ease of cleaning. Hardwoods such as birch, maple, beech and oak are used in a variety of widths and thicknesses as strip flooring. Parquet flooring is also made from some of these species. Floor coverings should not be laid until interior wall and ceiling finishes are completed.
SUB-FLOOR AND UNDERLAY REQUIREMENTS Sub-flooring is required under any finish flooring that is not capable of supporting specified live loads. The thickness of wood-strip flooring required for various support conditions
is shown in Table 41 (p. 308). When wood strip flooring at least 19 mm (3⁄4 in.) thick is laid perpendicular to the joists, no underlay or sub-floor is required for joist spacings up to 400 mm (16 in.), but all end joints must be staggered and be located over joists. When the wood strips must be run parallel to lumber subflooring, an underlay is required to provide support. When lumber subflooring is used under wood strip flooring, it must be laid diagonally and the wood strips can be laid either parallel or at right angles to the joists. Sub-flooring is required under laminate flooring, parquet flooring, resilient flooring, ceramic tile and carpet. A panel-type underlay is also required for these types of flooring when the sub-flooring is lumber. Some engineered wood flooring does not require an underlay.
