ZipWall introduced a mini-me version of itself with its launch of ZipDoor. The kit’s double-sided tape, heavy-duty glued-in zippers, and flame-retardant plastic sheeting make it possible to seal a doorway in less than a minute to provide a complete dust barrier, the company says. It’s ideal for locations with lots of doors (think hotels) or where there is a possibility of lead paint. ZipDoor comes in two versions: One for doors up to 3x7 feet and one for doors up to 4x8 feet. 800.718.2255.
