Päällystyskehystely

Päällystyskehystely is a Finnish term that translates roughly to "coating framing" or "cladding framing." It refers to the structural support system used in buildings to attach and hold exterior cladding materials. This system is crucial for ensuring the stability, durability, and weather resistance of the building's facade.

The primary function of päällystyskehystely is to create a continuous barrier that manages moisture and air. It typically involves a framework of vertical and horizontal members, often made of metal or wood, that is attached to the building's primary structure. This framework then serves as a substrate for applying the chosen cladding material, such as wood panels, metal sheets, or composite materials.

Beyond simply holding the cladding, the päällystyskehystely plays a vital role in creating a rainscreen. A rainscreen is a system where the cladding is separated from the building's weather-resistant barrier by an air gap. This gap allows any water that penetrates the cladding to drain away, and it also facilitates ventilation, which helps to dry out the wall assembly. Proper installation of the päällystyskehystely is therefore essential for preventing moisture-related damage, such as rot and mold, and for improving the building's overall thermal performance. The design and materials used for the päällystyskehystely can vary depending on the type of cladding, the climate, and local building codes.
