INSULATION MARKETPLACE SmartSHIELD -3mm 24inx10Ft ReflectiveINSULATION Roll, Foam Core Radiant Barrier, ThermalINSULATION Shield - Engineered Foil

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.

Worked great for my feral cat's winter shelters. It kept them warm and toasty. It was easy to cut and install in my shelters. It's pretty thick and stay in very well. I would purchase again.

This insulator works amazing, I heat my duck house and used this insulation to cover the entire interior of the duck house and it traps the heat in amazingly. Great product will be buying more for sure!!

actually 4 1/2 love this stuff definitely works in blistering heat and freezing cold easy to use but must be protected if used outside the silver part will come off and the foam can be crushed if to much weight is applied but even at that it works better than the similar kind better heating and cooling in my windows.....

The house I bought 3 years ago, came with a monogram Fridge and just a bunch of MONOGRAM products that were/are on their last leg being 15+ years old. Already having put like $5k in repairs, I decided, to wait (thanks to recent world events) to buy a new proper fridge and found a more budget friendly option via Chest Freezer Converters. THIS is where this product comes in. THE SHORT: IT WORKS AND IS GREAT. Pros: -Thin but DENSE. Has your standard Mylar on both sides, which is nice since some of these are actually ONE SIDED (weird), but uses an actual FOAM core. The Lowe's option uses bubble wrap. While being half as thick as the bubble wrap mylar option, has a way better insulation rating thanks to its foam core. -Given how thin it is, means it's super easy to cut. Cons: -While minor, is annoying; the tape used is that cheap cellophane tape and it does tear when removing it, and is also near impossible to see on this. Solution; thin masking tape. How I used it: Bought a 7ft Chest Freezer for $200, proper fridge starts at $500. Then at Walmart saw they made MINI kitsch milk crates for the desk. Bought 12 of those, four fit together in the bottom of the freezer and two on the ledge. BUT, them on their own wasn't good enough for refrigeration purposes. They, having holes in them, meant they cooled and heated quickly, risking spoiling foods faster when I opened the chest freezer each time. That's where this came in. Lined the inside of the crates with this stuff and now don't have to worry about the foods spoiling as quickly. Conclusion: Should have bought two rolls. Since man did I burn through this way quicker than expected. Would recommend. Won't add too much bulk, will add some insulation (obviously the thicker the stuff the better) to your projects, and is easy to cut/manipulate.

Love! I bought to line the inside of the houses for my ferals. Some are installed with straw. Some have a heating pad. But all the houses have this to line and works great! Even in -25 degree weather, it helped keep the house with straw 30 degrees and ones with the heating pads it helped keep them to 45 degrees.

I used this insulation to line the inside of a home-made 3D printer filament dryer. Unfortunately, the insulation seems to have done very little in the way of improve the heat loss through the sides of the dryer. The outside of the box still gets just as hot to the touch as it did before I installed the insulation. I have noticed that it will reach an internal temp of 80 deg C in a little over 24 minutes, where before it would take about 26 to 27 minutes to reach the same temperature. So it might have added some insulation value, just not as much as I would have hoped. but I can see I am still loosing a significant amount of heat conducting through the sides. Because after running for 90 minutes, the exterior is still holding steady at around 58-63 deg, which is the same as it was before the insulation was installed. I havent measured the amp draw of the heating element to see if that shows a reduction in amperage over time. but just a ballpark guess, the heating element seems to turn on and have the same duty cycle as it did before. (didn't time it before installing to get a baseline measurement, just not observing any noticeable obvious improvement). Otherwise the insulation was easy to install. I used a high temp double sided tape to secure it, which seems to hold well, The foil coating appears durable. and over 8 hours of continuous exposure to 80 deg hasn't damaged, discolored or otherwise affected the insulation in any way that I can tell.
