Is there insulation on the roof at all?One other thing - our building has insulation inside the steel outer walls. When combined with the sheetrock interior walls it’s very well insulated. In the summer it’s typically about $40 per month for just under 1800 square feet of air conditioned space. I thought we’d have to lay insulation above the suspended ceiling tiles but it wasn’t necessary.
Yes - the same as the walls, 3 inch. This is a picture of the inside back corner. Three of the walls are stick construction which made the interior walls much easier. This corner will be the backstop location for an indoor range if I ever get the backstop and exhaust fan sorted out.Is there insulation on the roof at all?
