Rated 1 out of 5 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 4 out of 5 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 out of 5 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 out of 5 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 out of 5 by Don't waste your money It would be great - if it stayed in place! But the adhesive backing on the hook & loop doesn't adhere to the "blanket" The blanket falls down within a few minutes. I think I spent more time on the ladder attaching the blanket to the fan than it stayed in place. No idea if it really works because it wasn't up there long enough. July 12, 2012
