Installation methods

  • Floating

    An installation method that can be used with a variety of materials, including laminates, engineered hardwood, luxury vinyl and rigid core flooring. In this method, individual planks (or in some cases tiles) interlock edge-to-edge to form a single mat-like surface that simply rests on the underlayment.

  • Double Glue Down
    Double Glue Down

    An installation method whereby the underlayment is first adhered to the subfloor with an adhesive, and the floor is then adhered to the underlayment. When using this method, it is very important to make sure that the right adhesives are used depending on the type of flooring, subfloor and underlayment in the installation.
