Aspen Aerogels Spaceloft 6mm Hydrophobic Silica Aerogel Insulation Mat 57" x 1 Linear Foot

Never go the chance to use this as dust just exploded from the plasitic packaging as I opened this. The dust is waterproof and it's concerning to watch it settle on your shirt tools, etc, and then watch it roll around when moved. It get's on things and stays on things. It can be washed off but, you have to use soap and be thorough and meticulous. My concern at that point was simply to safely get rid of it. In doing some research after the fact, I've learned that products on the lower end of the price range will have these issues as the materials used in the insulation mat binding are inferior. So the job now is to find samples of a better quality material.

i used this product to insulate some water lines in an exterior wall. i will update this review in a year, when winter comes to see if they freeze. this product is extremely dusty and difficult to work with. it's hard to get clean cuts with insulation knife or utility knife but you will get some good cuts. the dust is very fine and it will shed dust all the time you're working with it. even with a mask it was getting through. it also gets in your eyes so you should have some goggles if you're going to use this extensively. unlike many dusty products, it's actually not irritating. you will feel it in your nose and throat and eyes but it doesn't make them irritated so it might not be toxic. it's also waterproof, so if you wash it with water it just beads off. you will probably have dust all on your skin and notice it but if you use soap it does wash off.

Because the material can disintegrate very easily, I tried using spray waterproofing sealant. It enabled a pattern to be marked and cut with only the cuts releasing the aerogel so edges are sprayed after cutting. I think next time an art spray fixative for colorpencil pencil drawing because the spray is more controllable than what I used
