I was super skeptical about using this, my attic has always been on the hot side, improper insulation and no fan. Figured try this. Stuff is very strong, can't tear it but cuts easily with knife or scissors. For my attic a bit of a pain stapling it to the high rafters but eh, only have to do it once.Ok so I did half my roof one day, the next day it was 85 degrees out, super humid, heat index 95 blazing sun. Went in attic with my digital thermometer. Went a foot from the roof peak and measured the temperature on the OSB side I didn't cover, it was reading 130 degrees. Directly across from it, not even two feet away, measured the temperature on the foil side, it was reading 106 degrees. 24 degree difference in basically the same spot, wow, did not expect that. This is about 15 feet up at the peak, down about 4 feet from the floor level in the attic it was still about 18 degrees difference in temperature.Now had the entire attic been done I'm sure it would be lower than the 105 degrees, I truly did not believe this would make such a difference but it did. I already have noticed a difference in the house as far as temperature and how my AC unit runs less.LOL one other slight benefit is I have a large house and large attic but only ever had just one bulb in the attic for light, well, it is 50% brighter now since the entire ceiling is basically silver and reflects that light.Highly recommend this, I used two rolls cost me about $250 and my own labor and for sure that money will be paid back within months on my heating/cooling bill.

10/10 stars for this stuff. It's very tear-resistant as it has nylon strands woven into it. Easy to cut and install, seems very durable. Definitely a good value, and makes a dramatic difference in the temperature of my attic.

Don't listen to anybody who says all radiant barriers are the same. I discovered that with this product. I purchased this to put in my workshop, which is a metal building with spray in foam insulation. I added a mini split HVAC system this summer to the shop, but could still feel heat coming from the roof. I decided to add radiant barrier to the shop, to see if that would help. I had a left over partial role of radiant barrier from a house I used it on, but not near enough to cover my shop. I used some of that on a small section of the barn ceiling and it reduced the temperature down approximately 20 degrees. I decided to go ahead and do the rest of the shop and ordered this product. After installing one small section, I checked the temperature with my infrared thermometer gun. It only reduced the temperature on an average of 8 to 10 degrees. Yes it did reduce the temperature, but not enough to make a significant improvement. And, of course, I can't return this because I've already used some of the roll. Moral of the story; Do your homework before buying radiant barrier.

Works great for a reflective vapor barrier.

This is so easy to fit to sunny windows to keep the heat out. Easy to put up and take down daily.
