ABSTRACT:
The performance of a thermal insulation for a building surface6, subject to a thermal gradient emitting from the building interior, is enhanced by a neutral thermal gradient. For this purpose an electrical heating element1is adapted to release very low Wattages of thermal energy and is contained within an inner layer4and an outer layer5of thermal insulation. Adjusting the thermal efficiency of the insulation layers controls the magnitude of the thermal energy required to maintain the temperature of the element1at the equivalent temperature level to the building interior. The element1may be provided with a moisture controller and discharge sizeable quantities of thermal energy to dry moisture from the thermal insulation materials of the assembly.
