PVC foamboard is distinct from the extra-lightweight foamcore board, laminated of foam and card surfaces, used for indoor signage and modelling. Like PVC, closed-cell PVC foamboard is solid and has a very rigid structure. Where it differs is in its closed-cell foam structure, which makes it very light (as little as half the weight of solid PVC ...

Composite deck boards are sold in either grooved or solid sided versions. The grooved composite board is fastened with hidden deck fasteners or clips, while the solid board is typically face-screwed. Most composite deck board manufacturers produce lengths of 12, 16, or 20 feet (3.7, 4.9, or 6.1 m), 5 + 1 ⁄ 2 by 3 ⁄ 4 inch (140 mm × 19 mm).
Wood–plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA). In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials.
Plywood for flooring applications is often tongue and groove (T&G); This prevents one board from moving up or down relative to its neighbor, providing a solid-feeling floor when the joints do not lie over joists. T&G plywood is usually found in the 13-to-25-millimetre (1 ⁄ 2 to 1 in) range.

The density of the board, when evaluated in relation to the density of the fibre that goes into making the panel, is important. A thick MDF panel at a density of 700–720 kg/m 3 (44–45 lb/cu ft) may be considered as high density in the case of softwood fibre panels, whereas a panel of the same density made of hardwood fibres is not regarded ...
