Let me just say that this is a VERY GOOD QUALITY PRODUCT!! I decided to spend the extra money & go with the 5 mm thickness & I'm VERY HAPPY WITH IT!!! The temperature in my house has gone down at least 8°F since Installing the insulation. I am very happy with the overall value. I can say it is very heat resistant because I am also using it to insulate the exhaust from one of my inside Portable AC units & with it on there, you CAN NOT FEEL ANY HEAT COMING FROM THE EXHAUST HOSE. It is pretty easy to manuver to cut to size. It actually has pretty good sound insulation considering it's not the thickest available. I also did not have any issues with using adhesive on it. I really like the material it's made out of. I highly recommend that you spend a little money NOW to SAVE A LOT, LOT, LOT MORE MONEY 💰💰💰 down the road!!!! Review: Incredible - I needed insulation in a structure that I'm using as an office and didn't want to deal with fiberglass and all the mess that goes with that. I figured I would give this a try. Don't hesitate, this stuff is incredible. It's thin and light, reflective on both sides, and it's all in one - nothing else needed. No vapor barrier needed, nothing. We literally unrolled it and stapled it up, cut where needed and used aluminum tape for some corners. And you could tell it worked after just finishing the ceiling portion. Once the walls were done as well, you could really tell. It was 10 degrees last night and it was comfortable in the building. Turned on a small heater and the space heated up within 10 minutes. I'm actually sort of blown away, it's so good that we ordered more to do another space and we will use the leftovers in a chicken coop that we are building. It doesn't smell, doesn't tear, is waterproof, rodent proof, mold proof...but mostly EASY to install. It took two 100 foot rolls to do the entire 288 square foot space. Just cut it with scissors or a blade where needed, easy to get around electrical outlets. Easy to hold overhead while stapling it to the ceiling. I'll never buy fiberglass again. ## Features - EXTREMELY EFFECTIVE - Reflects 95% of radiant energy, perfect RADIANT BARRIER.

Lined the edges and bottom of each window just outside the window frame and cut the insulation to match. The industrial strength Velcro adhesive has continued to hold up even with 100+ degree days. This way we can remove it when we want. And it doesn’t look bad - nice and tidy over the windows. **Q: What is the R Value of the 5mm?** A: In the description... R-value up to 15.67 ( with one layer), up to 21.10 ( with two layers). **Q: Good to keep the heat in? Fig I could use it to cover my window** A: It should work either way **Q: Has anyone used this over crawl space vents to keep it warmer during winter?** A: It would work well, cut 3/8" larger than both dimensions and press fit. I should caution you, unless you are having a problem with freezing pipes, you should never close the vents in the winter, moisture will collect on the underside of the house above the insulation causing mold. Air movement in the un-conditioned space under your house is critical. ## Customer Reviews ### ⭐⭐⭐⭐⭐ VERY EFFECTIVE!!!! *by A***A on June 10, 2024* I bought this to insulate my windows & doors.

Then installed 5/8" sheetrock on the ceiling .The walls I put R15 between all studs, then I installed a layer of this Smartshield on the walls, then I installed 5/8" sheetrock over that and HOLY CRAP!!!!!! My detached garage is cooler than my any room in my house on a hot Texas day at 103 degrees. The temp is insanely constant in my new garage. I didn't know what to expect, but this has far exceeded my expectations. It was a bit of a pain to install the sheetrock over it because it compresses when you screw the sheetrock in. You can not counter sink the sheetrock screw too far as they will pop through, but if you take your time, the results are fabulous. Now I want to sheetrock my entire house and put this beneath. This is probably one of my smartest purchases off of amazon.
