Deciding which hardwood flooring construction is right for you.

Are you confused by terms like “on-grade” and “below-grade?  When you are selecting the construction of your hardwood flooring, there are a few things to keep in mind.

 Solid flooring can only be installed over plywood, oriented strand board (OSB) and wood subfloors. In addition, since solid flooring does not perform well in high-moisture areas, such as basements, it can only be installed in on-grade (ground level) and above-grade (upstairs) areas. Basement areas typically have a concrete floor and would require the flooring to be glued down, an installation method that is not suitable for solid flooring.

In contrast, engineered flooring can be installed on all levels over plywood, OSB, wood and concrete sub floors. It is important to note that engineered flooring has been designed to help mitigate potential moisture issues and is not a solid piece of wood.  Instead, it features a cross-layer construction that is designed to reduce expansion. Engineered flooring can be glued down or stapled. Engineered flooring that is a minimum of 3 inches in width can be installed using a floating installation method.

Before installing your new hardwood flooring, be sure to review the installation & warranty sheet for your flooring to ensure proper installation and care.These can be found in your product box or at
