    Love the look, quality, and insulation. It is however a heavy garage door. You will need at least 2 – 3 strong adults if you have to manually pull up. BE AWARE, if you unlatch the garage from opener while up, it will come slamming down due to weight ! I gave it 3 stars, as Clopay does not sell a panel section in the event your garage door gets damaged. only option is to replace the entire door !.
