Weatherproofing curtain walls

The façade surface can be chosen freely. The choice ranges from cladding with timber and wood-based materials, via mineral panels with various types of surface, natural and artificial stone slabs, to metal or glass surfaces. If the façade of an energy-surplus building is equipped with photovoltaic units, the design is also based on the principle of curtain walls.
