bought a house with an attached 24x24 garage no insulation or ceiling so open to the rafters. HS Tarm MB55 is in the garage along with a 60k BTU Modine heater as a blow off circuit/garage heater I almost have up and running. Plan on doing a lot more garage stuff as I weld and work on my own vehicles as well and hate being cold. along the one wall that my house is on I put 5/8" sheetrock up and regular insulation so I am looking for ideas on doing the rest of the garage. should I put a ceiling in at like 10ft and insulate that or leave it up to the roof (20ft at peak) as well as the garage doors which I am not sure about insulating that.
