The education on what to buy, your website, the ordering and the arrival was all wonderful! The installation went extremely well! I'm a 45 year old non-athletic single woman and I did my entire un-floored attic rafters over my bedroom, April 550 sq feet. (Yes I measured) With my order of 700 sq feet I was able to add some up the sides. I used a roll of foil tape and lots of staples and was thrilled at the results! It's not too cold yet here in central PA but I am confident in the product and application. The price couldn't be beat either btw! Thank you!
