The air circulation is worsening behind the surface of the facade, which will entail excessive accumulation of moisture in the insulation. This, in turn, leads to a deterioration in thermal insulation properties. The most common reason for this is the hydraulic protection film fit out of the seal due to the entry into the guides. As a result, this film will quickly become unusable due to constant fluctuations between the facade panel and the seal that occurs when air moves in a small air gap. It must be taken into account that the surface of the walls is uneven and, accordingly, it is necessary to leave a supply for the air clearance;
