One theatre went from 6000.00 in one year to est of 35,000.00 this year. We are insulating a 120 x 55 flat roof, replacing an entire 3rd floor full of windows, and installing new controls on our 500,000 BTU boilers. We are also looking at adding a pellet boiler.
Another theatre went from 3,000.00 to 16,000.00 estimated. More insulation and a complete spray foam wall behind the screen in our largest theatre.
