Facade sealing is a set of measures and materials designed to protect the outer layers of a building against rainwater penetration, moisture, wind and uncontrolled air infiltration. It includes the proper sealing of joints between façade panels, corner joints, flashings, window and door reveals, and installation penetrations.
Depending on the technology, expandable tapes, elastic compounds are used, windproofing membranes, The sealing of the façade is carried out by means of a system, system profiles or dedicated sealing kits. In prefabricated houses, the precision of the façade sealing is of particular importance, as even small leaks can affect the energy parameters of the entire partition.
Properly executed sealing prevents dampness in the insulation layers, improves the durability of the façade, reduces heat loss and supports the maintenance of a stable microclimate inside the building.
