Review: Excellent performance and easy to install—raised basement area by 15 degrees F! - 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.
Review: Dropped my heating cost 30% - 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!!

## Questions & Answers

**Q: This might be weird but can u sew it and it hold the stitching well?**
A: I sewed mine to curtains for my skoolie and it worked great the thread wanted to slip through foam so I had to make a few extra knots on end but overall worked well

**Q: how thick is it?**
A: Foam is 3mm thick.

**Q: How much does it weigh compared to traditional reflectix?**
A: It is probably half the weight.  It is very effective, very light, thinner than the bubble types, and can be used in many ways.  I use it as windshield covers, either inside or outside, for our car and I even use it for a very effective insole and canting shim for my ski and snowboarding boots.

**Q: Would this insulation work on the bottom inside of a greenhouse window?**
A: It reflects the sun away , it's very very thin . If that is what you are trying to do is reflects the sun out then it may work

### ⭐⭐⭐⭐⭐ Love for my feral cat houses
*by A***A on January 12, 2026*

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.
