Abstract (en)
A polymer foam underlay element (10) for flooring applications is provided imparting improved structural stability to the underlayment, each side of the underlay element comprising puzzle locking means (12, 14, 16, 18) engageable with the side of another underlay element having the same design. The puzzle locking means enable each underlay element to directly interlock with both four or six other underlay elements of the same design to form interlocking joints, the interlocking joints being directly observable from a top view.
