Aerogel Insulation Hydrophobic Mat of High Temp. Blanket 12''x12'',Thickness 10MM

I’m sure I missed it but be aware that you will need gloves and or a mask to use this. It’s a lot like fiberglass insulation. You don’t want to breath it or get it in your eyes or get it on your skin. It’s a great product. Just wanted to make everyone aware of safety precautions since I must’ve missed them.

I bought several of these. I re-manufactured a soft-cooler from Amazon selected to accommodate these particular sample sheets. The cooler was conventionally insulated with generic foam from the factory. By slitting the cooler's exterior just under the zipper -- I trimmed and inserted these into the four sides and used the trimmings to fill out the bottom. I hand stitched the 'cut' and sealed with a PU adhesive. Camping; I pre-cooled to mod'ed cooler with ice in a bag. Placed 2 lbs of frozen ground beef, 2 lbs of frozen butter, 9 lbs of cold beef cuts, 5 lbs of prepared pork-belly, & 2 packages of bacon with a few odds and ends and closed the cooler. The cooler went into a re-use single layer of bubble plastic with Mylar on one side which was folded down as with a Christmas package. This went into a convenient sized Amazon box and off I went for 7 nights and 8 days, car-camping. I was impressively happy that it was cold enough until the morning of the 7th day whereupon I consolidated my few items into the coldest of the conventional plastic bodied -- filled with foam, full sized coolers with everyone else's stuff in it that was 're-charged' with bought ice. This turned the bargain soft-cooler into a stellar performer that weighs next to nothing, empty. It works great for 4-half gallon-ish packages of ice cream -- which I used for the 2023 July 4th party ( ~ 90ºF ). Of conventional insulators -- there is no "tremendous" difference in the insulating R-factors. The greatest advantage in the myriad of choices is in *how* the insulation is installed and unit price per square foot. "Ball-parking"; Aerogels are *roughly* 10X more effective as insulators than foams, natural, or stone/ceramic fibers, spun glass, various cellulosic options or repurposed garment fibers. A closed-wall vacuum insulator ( Dewers Flask/Thermos ) is *roughly* 10X more effective than Aerogels.

Don't handle this with bare hands. The mechanical properties are poor. It might be a very good insulator, but: a) It's not that light. b) Emits dust of unknown risk.

I literally just opened this package and it would appear that fiberglass dust went everywhere. I wouldn't recommend opening inside like I just did. White powder residue on my hands as well. Can't speak to the quality of the product just yet but figured I'd give a fair warning to future consumers.

It is every thing the comments say it is and a great insulator. I put it on the top of the ceiling in my steel hull boat. Works great stopping the radiant heat from penitrating into the living space. I just left it in the plastic bag it was packed in so no mess.
