A protective covering for a lumber stack is constructed by providing an appropriately sized sheet of heavy duty heat shrinkable plastic material, folding the side edges of the plastic sheeting material inwardly along spaced apart longitudinally extending lines to form top and bottom layers and joining the ends of the top and bottom layers to define a top layer which is imperforate throughout its entire length and width and a bottom layer which is imperforate throughout its entire length and width except for an opening extending the longitudinal center line of the bottom wall from end to the other. A lumber stack is received through the opening in the bottom wall thereby forming initially upwardly extending rectangularly shaped panels which are folded downwardly and secured to the ends of the lumber stack. The portions of the plastic sheeting extending adjacent the ends and the corners of the lumber stack are then heated to shrink the plastic sheeting into secure engagement with the lumber stack.
A lumber stack protection assembly for receiving a lumber stack comprising a rectangular sheet of plastic material having side edges and end edges and folded along longitudinally extending lines each located inwardly from an adjacent side edge approximately one quarter of the width of the sheet to define top and bottom walls which are joined one to another along the entire width of the end edges, the top wall being entirely closed across its entire length and width and the bottom wall being entirely closed across its entire length and width except for a lumber stack receiving opening extending the entire length of the longitudinal center line of the bottom wall.
