I just wanted to give my 2 cents on the insulated Haas garage doors I had installed last fall. Over this past winter I used one less 250 gal tank of propane. My garage is split into two sections. One section is 1500 sq ft, with 1- 9x8 door[ kept at 63 all of the time. the other section is 900 sq ft, that is kept at 50 in the winter, this side has 1-16x8, and 1-9x8 door. I went with thR13 600, series doors. Overall I`m happy with them
