Easy to install, I used duct tape to secure it inside my cat house outside to help insulate it. It was good quality pretty thick. The outside cats seem to like it. So maybe it helped keep it warmer. I used the duct tape so that I could take it out in the summer and reuse it hopefully.

I made window inserts for my van to sleep in. It successfully blocks out sun, and deflects some heat mid-day. I also made various cooler insulation pieces that significantly improve efficiency, and I still have a 1/3rd roll left.

I insulated my garage door with this. It was easy to cut with sharp scissors and definitely cut down the heat load of the morning sun on my garage, though not as much as I had hoped. I don't have accurate data, but if I can believe my garage door opener interface it seems to keep the peak heat down by about 8-10 degrees vs. no insulation. Definitely worth the investment. I can still feel the heat coming through though when standing next to the door, although not as much as before.

We needed something fast to help with the heat in our 5th wheel and I found the SmartShield in lots of different sizes. It was a very good price and it arrived SUPER fast. Easy to manage (lightweight), cut and fit, it’s worked so well I bought it a second time to line the walls in the pantry, medicine cabinet, and in the closet-the heat was so surprising as it was only 90 degrees outside. It was just what we needed, and we got it in time. The hard part was finding something l could use to adhere it to the windows and walls but not remove paint or the wall material-blue painter’s tape did the trick. (For the pantry and inside cabinets I used a double sided tape that is reusable. So far it’s stayed.There are a lot of refectix materials out there, this one is like a foil-looking bubblewrap. It’s pretty versatile too as we’ve even used it to line the inside top of our ice chest to keep things from heating up too quickly.

It provides solid performance without the hassle, helping to keep your space more energy-efficient year-round.

The amount of heat this keeps out is really amazing. Old house, old windows, poor insulation.... During the 'dog days' of summer even with the AC running non stop, it would get fairly warm then cool off as the sun set. I did some research and put some pipe insulation over the AC exhaust (portable) and grabbed a roll of this stuff after reviewing most of the brands available here this one seemed legit and the right size I needed as well. Glad I did. Now, there's a heat warning and it's noticably cool upstairs. Not like before. This stuff works!

Este producto es muy moldeable. Yo lo quería para aislar humo de cigarro. Cumplió su cometido a la perfección. Además se puede sostener con clips negros de papel o simplemente moldear para rellenar. No despide ningún tipo de olor químico. Inclusive improvisé una bolsa para aislar productos refrigerados (para unas paletas de hielo) y se mantuvieron intactas. La hice engrapando las orillas. Ideal para personas con muy poca habilidad de hacer cosas manuales. Sugiero se corte siguiendo la guia de una regla Una compra excelente.

Bought this to use on my sliding doors glass windows which we never open to keep the sun out and this 50ft x 16 inch roll was more than enough to cover both doors

Easy to cut into the required lengths. Have used it on the inside of a garden shed but will have to wait till next week when the temp will be in the high 30's to see if it helps.. was delivered before due date.

I used this to insulate a small area of my basement for indoor seed starting. Previously that area was very cold, and had effectively no insulation between it and an outdoor crawl space (aside from a few semi-loose plywood boards), and the area was also on top of a big poured concrete pier/slab thing. So basically, the air was around 50 F in the winter and the surfaces were cold. Also, drafts (outside air) came in from the crawlspace through slits between boards. This is despite all the seed starting gear (lights, heating mats, etc.). In previous years I have even put a small space heater down there in an attempt to try to get the soil up to 60 F+, which is where I want it to start things like sunflowers.So I bought a 50-foot roll of this stuff and cut three 14-foot strips of it. I tacked one long strip along the area that meets the crawlspace. (Used a staple gun—not sure if that's the right choice, but it's what I had.) I also laid a long piece on the concrete surface (no attachment, just laid it down and put plant mats directly on top of it), then added a third piece that ran between that surface bit and up to the wall/crawlspace interface. I stapled the that third piece onto a wooden beam, and used packing tape to attach the lower pieces where drafts were trying to blow through. This allowed a mostly leak-free insulation shield about 6 feet "high" by around 14-ish feet wide. I put back the same temperature monitor that had read 50, and within a few minutes it was up to 55. Hmm. That's good.After I reinstalled all the seed starting stuff (a few low-power heating mats, four low-power LED lights), the temperature went up to 65 degrees and stayed stable (!!). I have seen a few dips overnight down to 62, but in general this area that was consistently 50 degrees F (WITH lights and heating pads) is now mostly 65 and up (at one point it reached 70, which is actually pushing it as far as seed starting is concerned). The space heater is gone—it would be way too hot at this point, and in fact I'm considering adding a fan or something, triggered in case the temp gets close to 70, just to circulate some of the heat away.For the price, I'm extremely impressed. This stuff definitely created a thermal barrier between the super-cold cement block that the seedlings sat on—that block is such a huge mass that there's no way a heating pad is going to ever warm it up (remember, we're in a basement and this is essentially a secondary foundation wall that just happens to be super wide). The insulation also created at least a basic vapor barrier on the interface w/crawlspace, blocking a lot of drafts and little gaps. The fact that it's so thin and easy to work meant I could also tack it up around edges and corners, which is where the drafts were the worst. I know this isn't really designed to be the only insulation in this use case (I might have been better off installing batts of fiberglass, and would certainly do so if I were trying to treat an entire basement), but it's cheaper, MUCH smaller, MUCH easier to work with, AND you can wipe it down (within reason—it IS possible to rip the shiny surface). If you're looking for something very thin with a good radiant shielding effect, this is it.The only downside I can think of is that the material is thin. While this is usually a positive, you do need to be careful with it, as it's possible to rip the foil layer and have it start peeling off. That's different from a lot of other kinds of insulation (fiberglass batts, foam board, spray...) where the material itself is real tough and workable. This is thin and precise—install accordingly.
