The spray shop was absolutely freezing due to the height of the existing roof. We brought the ceiling down to approximately 3.2 m from 10 m thus heating only one-third of the area.
We fitted a tile with silver foil on the rear for heat retention and laid insulation above the ceiling. You will see from the pictures that the outer borders of the walls were rigid metal sheeting. When we fitted the perimeter trim across the ridges, we fitted pre-ordered shaped insulation to stop heat loss. The client is absolutely delighted and the heating bills will be reduced enormously.
