Rated 1.0 out of 5.0 by Falls down This product is garbage. The Velcro sticks to the metal frame no problem but it won't even stick to the product it was sold with. This cover falls off within an hour or two no matter how well you clean the surfaces before sticking the Velcro to it and no matter how well you try to work the backing to the foam. I stuck the Velcro to the foam without hanging it just as a test and within 2 hours all of the Velcro had completely separated from the foam with no load on it at all. Absolute garbage. This is going back. December 16, 2012
Rated 1.0 out of 5.0 by Nope. The boxes in this store were years old. Dust.Should have known. The velcro strips were inadequate to hold the plastic. It dropped within 30 mins. Will tape it to ceiling. Pretty much a waste of $. Not even a one star. Would return but cut to size. November 22, 2015
Rated 1.0 out of 5.0 by Worthless I should have read the reviews. As everyone else said, the tape won't stick to the foil side. Fell down in minutes. Waaayyy overpriced. July 19, 2015
Rated 1.0 out of 5.0 by tape doesn't stick The tape does NOT stick to the insulating material, so the insulation cover falls off. The tape sticks to the attic fan frame, and the velcro holds fine. It is the silver coated insulated material that is the problem. We followed instructions exactly and even reverse rolled the material to remove the curl tension. Will return for refund.

Rated 4.0 out of 5.0 by Does the job after using glue gun to attach velcro. After installing as instructed I found it on the floor the next morning because the velcro adhesive came away from the thermal material. This happened two more times after reinstalling. I solved the problem after gluing the velcro to the thermal material and has stayed in place for a month. It really keeps the cold drafts out! December 5, 2011
Rated 1.0 out of 5.0 by velcro won't stick!!! The velcro won't stick to the cover, longest I've gotten it to stay up is 3 hours. Now the velcro is falling off the frame after being up there by itself for a month. I am returning this to the store. December 8, 2011
Rated 1.0 out of 5.0 by BAD DESIGN This item is overpriced. What you get is a piece of white flexible foam insulation that has a reflective surface on one side, and some adhesive velcro. The idea is that you cut the insulation to fit the size of the louver area for your whole house fan, stick your velcro up there, then apply the other half of the velcro to the insulating barrier and voila. Problem is that within a few short hours this insulating barrier will fall down because the adhesive side of the velcro will not stick to it. I ended up having to buy a tube of Liquid Nails specially made for foam products, so add an additional 5 bucks to the total cost. Of course, this approach is still easier and quicker than building an insulated box out of rigid insulation and crawling into your attic to place over the fan. November 6, 2011
Rated 1.0 out of 5.0 by This product is not a good value I measured correctly and applied the velcro strip to the perimeter around the ceiling fan. I then applied the corresponding velcro strip to the insulation to be applied. It went up real well to the other velcro strip but then in less than five minutes it fell down. After repeated attempts I finally went into the attic and laid it on top of the fan louvers from the attic side. I would not recomend this type of product insulation. It would have been more economical to purchase a piece of other type insulation and laid it on top of the louvers. I feel as if I wasted my money. October 18, 2011
