I ordered from Insulation4Less. Quick and easy online ordering and fast delivery. I purchased Prodex Total Insulation. Prodex was very easy to work with, it went up very fast and easy. I insulated the walls on our 30x40x14 pole barn. Hugh difference in temp!! 10-15 degrees F outside while 60 degrees F on the floor and almost 80 Degrees F at the ceiling. I installed it all by myself. I used some of the left over in my attic, I can tell the difference there as well. I liked ordering online at Insulation4Less. Great site for busy people. All the information I needed was available online. I got the product at a good price, I got it fast, and it worked well. Good deal all the way around!!!
