Abstract
A vinyl floor covering to accommodate wood subfloor contraction and expansion as well as rolling load incorporates a foamed plastisol encapsulated glass mat which may be cut to form pivot points and expanded under a controlled pre-stressed condition. The glass mat serves as a carrier during manufacture and an "elastic glass" reinforcing layer during use as either tension or loose-lay flooring. The floor covering may be a true hybrid surface covering which is capable of accommodating the dimensional change of a target subfloor by utilizing the characteristics of both tension floorings and loose-lay floorings.
