what do you guys prefer and why, a standard truss roof or the open type. I guess it could depend on shop size. I am thinking 40x60. I have worked in many steel shops and just hate the interiors being open. They insulation gets filthy fast and looks bad. I was thinking roof trusses maybe one end vaulted for possible lift, with structural panels for walls. Heating and cooling would be easier with lower ceilings, and give you the ability to section it off for differnent levels of work, a dirty area, middle area for fab and paint prep, clean area for painting and interior. Also I have thought alot about heating, I have painted in shops with oil and propane or wood heat, puts too much crap in the air and you have to shut them off. What about just a/c with outside heatpump/propane gas pack using forced air?
