External cladding for roof surfaces has thin coating reflective to electromagnetic waves and of high specific electrical conductivity applied to at least part of sides of roof surface facing sun

摘要

The thermally active roof cladding arrangement has a thin coating that is reflective to electromagnetic waves and has high specific electrical conductivity applied to the sides of the roof surface facing the sun or to parts of these surfaces. The reflective coating can consist of aluminum or tin foil and is protected against corrosion by a transparent, air sealing and water-repellent coating.
