Kirkwood Il. | My steel bld put up in 2000, has a 1/12 roof pitch. Used 4" heavy foil backed fiberglass ins between sides and roof, then 7' Galvenized siding around lower inside with insulation exposed to top of walls and ceiling. The 1"/12" pitch eliminated need for a ceiling liner, mounted 10' florescent lights directly to purlins(sp) roof supports. 3' sky light along entire south wall. At the time, total cost was less than wood. | |
