A building, over a period of decades or even centuries, represents a major historical ideal and/or material value. But even the best materials fatigue and wear out after years of exposure.
In order to preserve the value, a building must be constantly maintained. Only in this manner can the wear and tear from age, use and weather influences be compensated.
The Hetzel + Sponheuer GmbH & CO. KG links old buildings with new, sound and sustainable technology. Old building and processing techniques must be known and respected so that, e.g. the new façade, physically restored to other areas of the building, harmonizes the goals of esthetics, maintenance, weather abrasions as well as energy savings.
