Do You Know What A Floating Floor Is?
A hardwood floor is a floating hardwood floor if the floor is not
glued directly to the sub-floor, but the individual floor boards are
glued together. The floor is held in place with its own weight instead
of glue. Floating floors are ideal when your sub-floor is uneven or
when you are installing over a pre-existing ceramic, vinyl or wood
floor.
