Abstract
An underlayment assembly comprising an underlayment with an upper and a lower surface, an adhesive layer disposed on the upper surface, and a release [layer] fastener disposed on the adhesive layer, optionally with an adhesive layer on the lower surface of the underlayment, is disclosed. One or more performance enhancing layers, such as foam and solid layers, can be disposed between the underlayment and the adhesive layer to modify and/or enhance various properties of the underlayment. A primary fastener comprising part of a hook and loop fastener assembly can be attached to the upper surface of the underlayment. Mechanical fasteners, such as staples, penetrate the underlayment assembly and engage a structural support member to attach the underlayment assembly thereto. Methods for installing a surface covering over a structural support member using the underlayment assembly are also disclosed.
