Very heavy duty, good 2 sided tape for mounting/sealing but does take off a small amount of paint when removed. Magnetic closure works well and is much better than zipper type closure - which many times does not get zipped closed after repeated entry/exit. Had to mount one curtain in a hallway, not a normal door entry application and certainly needed the push pins included to make the curtain mounting at ceiling more secure - since much heavier duty than other closures.
