  • Shield
Size: 16"x10ft
Have a room full of canning and when I saw this for the window to protect from the sun I bought it and my husband helped me put it up and keeps sun out and keeps the room very cool for our canning.

  • Easy to install
Size: 16"x50ft
I have a storage room on my patio that had no insulation. This was easy to install and will hopefully cut down the heat from the afternoon sun.

  • Works well, smell I can do without
Size: 48" x 10ft
Just put this up in my window yesterday. The sun hits my window with a vengeance in the morning, as my house faces east. Seems to work really well, I noticed how much cooler my living room is right off the bat. But one thing I can do without is the smell of heated metal. It literally smells like something is going to catch on fire. Hopefully it wears off after awhile or I’m going to have to replace it. ... show more

  • Just perfect.
Size: 16"x50ft

  • Great insulation
Size: 48" x 50ft
This stuff is truly amazing. Made a windshield screen out of it, and it is crazy how much heat pours in when we take it out of the windshield. We used foam board to insulate our campervan, but if I'd known about this stuff, I would have used it instead.

  • Nice and shiny, but poor insulator
Size: 16"x10ft
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. ... show more
