Working on an elementary rule of efficiency to reflect radiant power away from the foil and disperse it throughout the building is that of reflective foil. Including steel building systems, since World War II, reflective building insulation has become accepted for a number of projects.
The control of heat transfer is central to thermal handling in most structures. In general there is a contrast in temperature for the exterior and interior of a pre-fabricated, pre-engineered steel building. Up to the time when cold and heat is consistent across a given area heat usually moves from high heat areas to a cooler region. The application of insulation is to stop this process in very warm seasons, to hold back heat from being transferred into the all-steel structure. Conversely, you depend upon the insulation to stop the removal of heat outside of a pre-engineered steel structure in cold weather.
