Solid Wood Floor
A Solid wood floor is made of 100% hardwood and has a thickness of 3/4''. Boards have micro v-joints on all 4 sides and are of random lengths. Solid wood flooring can be nailed or stapled to a subfloor. It should be installed on the ground floor and on upper floors, but is not recommended for a basement, due to the humidity levels that could compromise its stability.
Consult the Solid wood floor installation guide for more details.
