Väliseinien

Väliseinien is a term used in Estonian architecture and construction to refer to interior walls. These are the walls that divide rooms within a building, as opposed to välisseinad, which are exterior walls. The function of väliseinien is to create separate spaces for different purposes within a structure, such as living areas, bedrooms, bathrooms, and kitchens.

The materials used for constructing väliseinien can vary widely depending on the age of the building, its construction method, and aesthetic considerations. In older buildings, they might be made of brick, stone, or timber framing filled with various materials. In modern construction, common materials include plasterboard (drywall) on metal or timber studs, concrete blocks, or reinforced concrete. The choice of material impacts the wall's structural integrity, sound insulation properties, and fire resistance.

Beyond their primary function of spatial division, väliseinien can also serve other roles. They often house electrical wiring, plumbing, and ventilation systems. Acoustic insulation is a significant consideration, especially in residential and commercial buildings, to minimize sound transmission between adjacent rooms. The surface of väliseinien is typically finished with plaster, paint, wallpaper, or tiles to provide a decorative and protective layer. The design and placement of interior walls are crucial elements in architectural planning, influencing the flow, functionality, and overall ambiance of a building's interior.
