• Floating hardwood floors actually refer to a type of installation process that is used with many Engineered Hardwood floors. Rather than gluing-down, stapling or nailing down the planks to the sub-floor, the hardwood floor "floats" freely over the sub-floor with the use of cork or foam underlayment.

• The wood planks are interlocked together but never fully secured to the sub-floor. Some require gluing the tongues and grooves together while others incorporate a special tongue and groove locking system that requires no glue. Glueless floating floors have a specially designed tongue and groove system that locks the planks together. This is the same locking system used with many laminate hardwood floors.

• The advantage to a floating hardwood floor is that you can install the hardwood planks over a wider variety of sub-floor materials, such as: OSB (Oriented Stran Board), plywood, fully-cured concrete slabs and some hard surface type floors. You can also install floating floors on all grade levels, meaning it is not subject to climate conditions. Floating wood floors are offered in all the same species, colors and widths as engineered hardwood floors. The only difference is within the installation process.

• Floating hardwood floor Installations require much less labor and do not require as much skill, making them ideal for DIYers and homeowners. This means you may buy a better grade of engineered hardwood, since you are saving on the installation costs by doing it yourself. You will still need some power tools to cut through the hardwood planks and under the door jambs. Any trims and moldings should be attached to the walls, never secure the moldings to the floating hardwood floor. A thin plastic padding is required to be laid on top of the sub-floor before installing the planks. This helps the floor float freely over the sub-floor. There are other underlayment materials that are used for specific flooring needs. For example, if noise levels need to be reduced, then a cork underlayment should be used on the sub-floor.
