good info on the garage doors. doors that roll up in a ball are called rolling steel doors the insulated ones have an r-value of maybe 4.5, however sectional doors can get an r-value of nearly 26 lift clearance would get the doors up and out of your way spending 1,000 on a jackshaft motor isn't necessary as a 3" track system with a solid shaft and lift clearance would operate very smoothly.
