Abstract
A carpeted surface is protected with a temporary carpet protection sheet that includes a lightweight non-woven or knit fibrous material laminated with a resin backing into which at least portions of fibers of the fibrous material are embedded, or to which resin of the fibers is directly and chemically fused. Male touch fastener elements extend along the backing and are arranged in spaced apart fastening regions adjacent the longitudinal edges of the fibrous material. The male touch fastener elements are configured to be both releasably engageable with the hook-engageable fibers of the fibrous material, when the protection sheet is arranged in overlapping fashion, and releasably engageable with looped carpet tufts. A protection system features multiple lengths of such protection sheet joined by hook seaming tape.
