SmartSHIELD -3mm 48"x50Ft Reflective Insulation roll, Foam Core Radiant Barrier, Thermal Insulation Shield, Commercial Grade - Pure Aluminum

I did a ton of research and read a ton of reviews on a non-bulky, but effective radiant barrier for my garage door. The Georgia heat can be oppressive and the sun tracks right in front of my garage during the hottest parts of the day making it a sauna. This also causes the rooms next to (and above) the garage to heat up. I chose this insulator based on the reviews. This is truly great stuff. Easy to cut. I bought some aluminum tape for the edges just in case it came apart when I cut it but I didn't need the tape. I measured 5 times, cut once, and it went up like a dream. I used 3M double sided foam tape to help stick the middle to the garage door but tucked the edges of the insulation under the molding of the garage door panels and hinges. Worked like a charm and the results are so much better than I anticipated. The garage isn't nearly as hot as before and nor are the other room. I'm going to use this stuff in my crawl spaces, on my attic door and everywhere else I can think of. I'll use a staple gun for those areas. Can't say enough good things about this product, but this is enough for now.

We used this material to cover & insulate windows, and it's the best window insulation I've ever tried. It cuts very easily, maintains its shape beautifully, and can be installed over windows in minutes. Best of all provides outstanding protection from the cold! Plus it's definitely reusable, so next year's insulating will be even faster and easier! I HIGHLY recommend this product to anyone who covers windows in the winter.

Easy to cut, and made a huge difference in our hybrid RV. Only complaint is that it tears easily, not very durable

Easy to work with. I had some shifty workers do insulation in a metal shed. The neglected to apply a moisture barrier, so I am having to remove all o the wall board and redo the insulation myself...no more trusting others... I ordered this to use under the fiberglass insulation as the moisture barrier. I am amazed at how easy it is to work with. If I had found it before I could have saved myself from wasting $1,000 on labor. I have ordered a second roll to finish the job. Thanks for such a great product.

I was pleasantly surprised at the thickness and strength of the insulation. I was hopeful it would be strong enough to use as an insulation blanket for my garage door--it was! I used self-tapping metal screws through fender washers with very good success. No tearing even with just a few screws as I began the installation to hold it in place. I'm using it to keep the heat out of my garage (which faces south-west) in Southern Georgia. I'm very happy with the product and the distributor. They have sent two emails to make sure I'm satisfied with the product and to make themselves available for questions. Very good price for a quality product that is doing its job very well. I recommend it.

I was amazed at how much of the ductwork we covered in an unheated crawlspace. I bought the 24" X 100' roll. The house is a ranch style and there we long runs. We got almost all of the ducts covered. It isn't a high insolation value but it was easy to work with, cutting with a knife and scissors and is an improvement on bare metal ducts. Be sure to buy metal duct tape. Crawling around was the difficult part.

Not especially effective. Two layers of this was less effective than a single layer of the foil bubble type. The application was on a tank chilled to about 35F, and the outer layer of this wrap felt decidedly cold.

Used to insulate underneath a Inclosed porch. Ordered 4x50 feet roll and cut to size to fit between 14.5 x10 floor joists. Stapled to bottoms of floor boards.
