- Engineered Floors:
These are strips of engineered wood that are glued, nailed, stapled, or floating directly to the sub-flooring underneath. This application can be installed above, on or below grade.
- Floating Floors:
This type of flooring usually has a built in locking system that locks together with each other. If gluing is required; it is used to connect each strip of hardwood to the next. This type of pre-finished hardwood essentially "floats" over the sub-floor and has a cushioned padding underneath it. This flooring can be used over most types of sub floors.
