Attic foil is tough material, no issues with tearing - superior to cheap stuff at local hardware store. Easy to work with. My attic is walk up with flooring in 1/2, blown insulation in other 1/2. Insulation installation certificate claims R-30 and building envelope is well sealed (checked with thermal camera) except one duct boot (I'll get to this fall). Completed steep hip roof section by myself but would have been a lot easier with someone assisting. Remaining sections went faster with sons help. Instructions, online faqs, from this company are honest about what to expect in installation and performance. Had extensive temperature/humidity monitoring before/after installation. Located in Raleigh area, temps taken over mid summer. At peak of hip roof, not much difference (not important from energy savings perspective) but at top of insulation and attic floor late afternoon high temperatures were 5-12 degrees lower. More interesting, the temperature dropped faster in late evening/night - I presume because insulation may have absorbed less heat? Overall savings in electric is a bit difficult to quantify as youngest son moved out and some other minor improvements made at same time - reduced average electric bill by 17% BUT NOT sure how much can be attributed to barrier.
On interior, upstairs conditioned space now takes much longer to heat up with AC off during day, doesn't get as hot (~2-3 degrees less), and takes less time to cool in evening when we get home.
Assuming a home has adequate insulation and is sealed well, I doubt this barrier would have a reasonable payback if installed by contractor. For DIY, I believe it is worth the time and cost. Besides, it's shiny - who doesn't like shiny stuff :-).

Between blowing more insulation on top of existing R30 and installing AtticFoil, I reduced my bill by 500kWh, which was about 1/4 of the bill in Phoenix, AZ. Taking a comprehensive approach to energy saving is key. I can feel the heat blowing up in between the roof and AF as I stick my face in the rafters. For the cost of attic foil as opposed to alternatives, it is an easy choice. Much cooler in the attic, wish I could have data- logged temps... Overall, this was an extremely rewarding, interesting DIY project.

BEFORE installation of AtticFoil: During most of the summer, our home's central air conditioner was able to maintain a comfortable level inside. However, when the outside temperatures reached 100 degrees and above, that same comfort level could not be maintained between mid-afternoon through the early evening hours.
AFTER installation of AtticFoil: We applied this product to the attic ceilings in both our home and garage. It's like adding a shade tree over our entire home even though we have no shade trees in our yard. We've now experienced 107 degree days and weeks of 100+ degree weather. Our air conditioner is able to maintain a comfortable level all day long. We are very, very satisfied.

Performance wise, it reduces the top surface of my ceiling insulation temperature from 110 F to 100 F degrees. Between attic foil, window film, and a "sun sail" in the back yard, I was able to take the hottest west facing bed room in the house, and make it the coolest room in the house. By putting a box fan in the access hatch, I was able to hold the attic temperature at 85 F (instead of 100 F) to survive in the attic noon in July.

We enrolled in the OG&E Smarthours program. Looking for ways to reduce our bill, it suggested mrre insulation, i.e. sprayfoam. When we researched the cost for it, WOW is all i can say. To insulate our attic, if we did it ourselves, wouldve ran around $6000!!! Not to mention if it is not installed properly could lead to a all sorts of problems. I saw a video of a couple that had sprayfoam improperly installed and they had to completely remove the roof of their house, from the ceiling all the way up!! It cost them $60,000 plus to fix it!!! I searched for other methods and AtticFoil popped up. Having my heating/air unit in the attic made perfect sense. There are NO WORRIES about installing, not to mention that its super easy to do. I used an infared thermometer while installing JUST to see if there was that much of a difference...WOW again!! I have a temp difference of 22-26 degrees. Ive told all my family and friends about it. My only regret is that i didnt know about this stuff sooner. I cant wait until next year to see how much difference its made in my heating/cooling costs.
