Solid hardwood and engineered hardwood flooring
Traditional hardwood flooring is available either as a solid 3/4″ thickness hardwood product manufactured with tongues and grooves on the edges of individual boards, or as an “Engineered” flooring product that has been manufactured as plywood.
Engineered flooring has multiple plies of wood cross-banded to form a dimensionally stable “board” with tongues and grooves. It is manufactured for use in installations where the dimensional stability of solid wood products is questionable.
Engineered hardwood flooring was originally designed as a stable product suitable for installation on concrete slabs without the need for a wood subfloor, but it can be installed on both concrete floors and wood subfloors. It can be laid in mastic, nailed down, or “floated” on a cushion pad depending on job conditions and requirements.
Your professional hardwood floor installer will be able to help you decide which type of flooring and method of installation is most appropriate for your specific project.
