Where is the best place to get a 16x8 r18 insulated garage door. Any good online discounters? Also I have a 12 ft ceiling but the lift is not close enough to the door to hit it when up. I like to install the door is high as possible but still use a standard opener (as opposed to the side openers since I don't like the extra slide lock device). If I go with a std opener can I still mount door with a high lift option?
