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

Product is very good and strong in spite of been thin. I started to install it on my attic and is only partially covered,however I already lower the heat by at least 10 to 15 degree F.

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.

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.

Used this in my tin roofed shop and with some foaming the place it bearable in the Texas summers and winter. Used it on sub floor and laminate. Eli mated the heat.

Put it in my attic check the temperatures no difference horrible product waste of money

I'm comparing this to the original attic foil from attic foil.com. that i used in my attic. I went cheap this time because its for my garage. Quality is not there. It rips easy . Had a problem stapling it up to the rafters it kept tearing from staple had to keep going back and to re staple. The original attic foil is more dense and heavier almost rip proof. On a positive note you do get quantity, I have a lot left over. I feel that it works ok blocking the radiant heat. Could be better.
