A Better Doorway Seal
Ever need to seal an open doorway during demolition or when sanding joint compound or painting? When I need to do this, I cut a scrap of cardboard 1 in. narrower than the width of the doorway and 8 in. longer than the height of the doorway. ZipWall poles provide the tension to the top and bottom flaps. The sealing effect comes from 1/2-in. foam pipe insulation slipped onto both sides of the cardboard insert, creating a snug gasket.
