"Great product! I didn't realize how tough this foil would be. I've had it installed since August 2018 and now that we are about to enter summer, I can give a thorough review.
Installation: easy, you do need a strong pair of scissors, this foil is not flimsy by any means. I'm glad too, because in my attic with all the bends and turns, nails and sharp things, this foil didn't tear... at all! I almost didn't like how tough it was until I got to some areas where I was very glad it didn't tear!
The most important question, does it really work? My electric bill is normally 168 to 200 during the summer and I kept the air around 79 during the day and 85 in the evening for the lower unit and the upper unit is generally around 78 all day. The bottom unit is programmable 7-day and the upper unit is non-programmable.
After installing attic foil, my winter electric bill was $116 and currently, my highest right now in May is $117 and the air is kept at 73. More comfortable, the air runs far less and I'm able to keep the house much cooler at less cost. We'll see what it's like in the dead of summer when it hits 95 outside.
I'm impressed. I would definitely encourage homeowners to attic foil for home energy efficiency!"
