Review on Dust Barrier Kit - Magnetic, Self-Closing Plastic Sheeting for Containing Construction Dust in Doorways - Ideal for Bathroom, Kitchen, Hallway Remodels - Fits Standard Doorways (4'W x 7.5'H) by David May

I got a couple of these based on good reviews and the zipper looked terrible. They work very well and close as advertised. The tape that came with it looks like regular masking tape, so you might want to use something more durable. My situation allowed me to staple them together, so I didn't use them at all. Unfortunately I had to return the unused ones because my cats had been watching me enough to realize they could do the same, rendering them useless for keeping cats out of the work area. Sigh. Replace zipper.
