The facade is designed, often representative of the visible shell or outer skin of a building.
The most important task of a facade coating is to protect the substrate from moisture. If moisture in the form of water or steam excessively into a masonry, it can cause damage to the building fabric. But walls are wet to avoid even the energetic point. Than ever a damp wall, the more heat energy dissipates it. This is noticeable in energy loss in the winter months. The topcoat met here one of the durability of the facade an extremely important function, only the best protective coating can ensure a long-standing and considerable protection perceiving facade.
With algae and fungi facades are affected predominantly by external heat insulation. In contrast to the massive masonry exterior insulated walls have a lower heat storage capacity of the thin outer plaster cools down quickly, since the supply of heat is prevented from building here. The result is that the walls in particular hardly dry sides facing away from the majority of sun. There is also the risk of condensation on the surface of supercooled facade. Precipitation moisture to support and accelerate this infestation.
