Just like the name solid wood flooring is a solid piece of wood unlike engineered wood which is layers of wood with a laminate top layer. Solid wood flooring comes in strips, wide planks or parquet squares. The strips usually come in 1 ½ “ and 3 “ wide. Planks will range anywhere from 3 to 7” wide.
The most popular hardwood strips are unfinished in either red oak or maple since it is affordable, attractive and you can choose the stain color for your floor.
Prefinished wood flooring can cost more than unfinished but it has some advantages like not having to finish the floor and comes in thinner planks so transitioning to another room can be easier. Another consideration in choosing solid wood flooring is the sustainability of the forests.
Solid wood flooring is more susceptible to changes in temperatures and moisture in the air. As a result, your solid wood needs to acclimate to your room temperature and moisture prior to being installed. Also, a gap between the wall and planks needs to be left to allow for expansion & contraction of the wood.
