Furthermore, välisseinu offer protection against weather elements such as rain, wind, and snow, ensuring the longevity and comfort of the building's occupants. The design and construction of välisseinu can vary significantly depending on the architectural style, climate, available materials, and building codes of a specific region. Common materials used for välisseinu include brick, concrete, wood, stone, and various composite materials. The aesthetic appearance of välisseinu is also a key consideration in architectural design, as they form a significant part of a building's visual identity. In addition to their structural and protective functions, välisseinu can also incorporate elements like windows and doors, which provide access, light, and ventilation to the interior spaces. The proper installation and maintenance of välisseinu are vital for the overall performance and durability of any construction.
