2-Pack of Emergency Mylar Thermal Blankets to Help Retain Heat in Cold Conditions

Michelle: I haven't had to open one yet but looks to me they will work great

onef: Most emergency supplies never do get used or tested--so it occurred to me that I should actually put some of these space blankets to use and see whether they work for insulating a space (and if they might really save your life in a winter emergency).

I've taken a few of these blankets from the pack, opened them up and draped them over a bakers' rack to close it in, with some duct tape to secure them. The duct tape adheres to them very well, and while the mylar material feels so flimsy you'd think it would instantly tear, they're actually pretty hard to cut. I had to use scissors to make openings for cords, because I couldn't get through the mylar with just my hands. However, the mylar DOES scrape off pretty easily, leaving clear plastic behind--so don't drag these around a bunch of sharp objects or you'll lose that mylar coating.

The grow lights on the shelves inside this enclosed bakers' rack produce some heat, but they're in an unheated shop space that is currently sitting around 45 degrees F. It is protected from wind, and kept above freezing, but there are minor drafts. Without any enclosure, the lights were not capable of heating the trays...

Pablo M.: These are handy items and are of the same quality as the more expensive single use survival blankets that I've seen.

woodworker: I take one camping, keep one in the car, they're cheap and lightweight but could save a life. We've used one to make an improvised ice box, also they are high visibility so can attract attention if you need it. Lots of uses for a space blanket, and inexpensive enough to use one in non-emergency situations. They're pretty much one time use, so keep a spare.
