This item does not work for me. I have a standard attic stairway that pulls down, but HEAT exudes from it. This product has not blocked it at all. Even my contractor is perplexed. Big disappointment. Also, NO directions are included.
It seemed to be what I was looking for. After reading the directions and several of the reviews I installed using a combination of slats and tape. The zipper seems to be a bit fragile and I was careful after reading the reviews but it is not a space I access often so it shouldn’t be a problem.
