Finishing up framing a 13'x36' shop area within my large shop. Walls and 8 foot ceiling fully insulated. All surfaces are 1/2" oriented strand board, along with a couple of double insulated windows looking into the bigger shop. There is 4" insulation in walls and 6" in ceiling. Concrete floor with vinyl tile. Power available for heating would be either electricity or propane.

Would like to maintain 50°F to keep machinery from rusting. Outside temperatures average around 36-38°F through the winter months. I don't require a warmer temperature for working. Can always place a small propane heater next to me if I'm going to stand in one place for a long time.

All suggestions greatly appreciated. BTW, ceiling will have 8 four-foot four-lamp fluorescent lights.

Thanks, Ivan Vegvary
