72 HRS MIL-SPEC Emergency Space Blankets – Mylar Survival or Emergency Thermal Blankets for Camping, Hiking, Marathon, First Aid, Emergency Preparedness, Extreme Weather, Shelter (4-Pack)

I noticed a heat wave was forecast so I began looking at purchasing reflective foil for the roof. The bubble wrap kind is probably the best kind but it was about 300.00 & I didn't know if it would work.When I realized that 12 of these 55" x 88.6" sheets was over 400 square feet I knew immediately that for about 20 bucks I could test my theory by velcroing these to the roof. I used 4" x 2" velcro strips (one on each corner) & also some maximum strength 2" tape to help prevent the wind from catching underneath.I've done about 82 percent of the roof so far today. <time passes> I finished the roof this morning & put one of these on a wall facing the morning sun. I can say for a certainty that the foil has helped reduce the cabin temperature but by how much I can't say.It's 96 degrees out there at this moment approaching 3 pm & expected to peak at 97. In the RV its only 77 degrees & I can make it seem cold in here if I want by turning one of the ceiling aircon vents towards where I'm sitting. Got so cold yesterday that I turned them all pointing away from me.So plastering these on the roof & over a couple of exterior faces has greatly reduced the heat issue. I've only used 10 of the items leaving 2 more in case I think they'll help. The alternative was 250.00 worth of foil covered bubble wrap which is said to work better. I wanted to experiment with this first to determine if the value of a more expensive solution was justified. After this experiment I think it is.

It comes with two in the package it’s a good thing to have a new vehicle or if you’re going on a hike just a slip in your pocket or is very small and compact but it will keep it covered and warm and dry I liked it so much that I bought 12 more to put in everyone’s car in the family

Although I have not had to use these in an emergency situation yet, as I just bought them, I took them out of the bag and they are so much thicker than the kind you get at Walmart or the dollar store, I have put two in my car for emergencies and bought them for my adult kids stockings as well

I used it over my camping hammock with 5 degrees celsius outside. I felt like I was sleeping in a house. It ripped when folded it. They are single use emergency blankets after all.

I bought a 12 pack of these emergency blankets because I was tired of wasting tin foil on my windows every year. I now have a renewable space blanket I can hang up over my windows to keep the summer heat out! I was amazed at how durable these blankets are. They are also super lightweight!
