1000 sqft Diamond Radiant Barrier Solar Attic Foil Reflective Insulation 4x250 by AES

I'm giving this 5 stars because I know for a fact by testing with my laser thermometer that this stuff works! I also have seen lower electric & gas bills in both the summer and winter months. Being in the attic with a sloped roof made it not so easy to put up, but once you got it figured out, it goes up just fine. I also have another similar radiant barrier in the garage that wasn't as high quality but works as well. Point is, these radiant barriers are worth the money. Pay a friend with lunch to help you install it and save yourself some money.

Spent half the day installing in weird bonus room behind the closet wall space. Stapled in place and could feel difference when applying to underside of roof. Got all walls and laid out on top of ceiling insulation. When originally opening the closet doors, you could feel heat come out and the closet walls were very warm to the touch. This should make the overall bedroom cooler in summer and warmer in winter.

Great value for radiant barrier roll. It's lightweight but very durable, requires a razor or scissors to cut it so won't rip unintentionally. Keeping my attic cooler so it seems very good investment and value. It's not make as insulation but rather reflecting the radiant heat so installation doesn't have to be done in an exact way and missing sections is not the worst thing. Best done with another but alone works fine.

i used this in my attic- stapled to the bottom of the rafters. it works amazingly. instant difference. in south texas and i can leave my windows open on an 85 degree day. looking forward to major savings this summer. here's the caveat; it is not durable and rips easily so that makes installation tricky if you're not careful.however, that does not impact it's effectiveness at all. it still reflects 97% of radiant heat. you just might have to re-staple or use foil tape during installation.another point; this 4 foot wide product is not for truss roofs. if installing this product horizontally on the rafters you have to cut the barrier around each jack support. it's awful but i got it done. do yourself a favor and buy the 26 inch wide product so you can install it vertically on the rafters.

Smart purchase, easy to install, energy-efficient!

Sure doesn't look like a 250 foot roll. I will update this review when I do the install and I am able to measure it.

Cut it to 22.5" +12'-14', then went down the middle of the attic, an rolled it out on top of existing insulation. Could tell the differance in about a day !!Only have to use s very small heater to heat a 10+25 room with this in the attic, an taped on the inside of the outer wall from floor to ceiling !!

Do not buy this stuff. It's horrible. It is hard to cut even with new blades, used the strongest glue it stated up over night after 7 hours of putting up. Plus if you have to overlap it will not glue to itself no matter what you use. Hell I didn't 40 bucks on first hours trying to find one to work with it. Just not worth the hassle when there's foam board with the same stuff already attached. Trash just normal buying experience lately.
