I am also looking to replace 2 old wooden garage doors and in talking with the nearest garage door company in my area, he mentioned the Garaga door. He also carried the Wayne Dalton and others, but really endorsed this door. It is made in Canada, and the Standard+ insulated door has the following specs: 26 gauge galvanized steel (G-60, Z-180) with 5 coats of protective finish applied in the factory. It comes with a baked on polyester based paint, primer, galvanization, steel, galvanization, primer. It has an R-16 pressure injected polyurethane foam center, wood end blocks to create a thermal break and flexible "U" weatherstripping on the floor. It says nothing about the top of the door. It also has interlocking weatherstripping between the sections of the door. Their website is www.garaga.com and it comes with a "limited" (my quotes) lifetime warranty. Hope this is helpful and would appreciate any additional info/feelings you may have.
