Cold Roofs

In Cold Roof construction the insulation is at ceiling level, and there is an air gap between the insulation and the roof surface.
With cold roof construction, the under-surface of the metal roofing will at times be quite low, so the primary tool of managing condensation is to control the concentration of water vapour in the attic space.
As some condensation is inevitable, this must be managed to ensure it is not excessive in terms of degree or duration.
