vég

Væg is the Danish term for a wall, a vertical architectural element that encloses, supports, or divides spaces within a building. It can function as the outer envelope of a structure or as an internal partition between rooms.

In construction, vægge are commonly categorized by their role. Ydre vægge are exterior walls that provide weather protection, insulation, and enclosure. Bærende vægge, or load-bearing walls, carry structural loads from floors and roofs. Skillevægge, or partition walls, divide interior spaces without bearing substantial loads. In modern buildings, many walls are non-load-bearing and rely on other structural systems, such as frames or slabs.

Materials and methods have varied over time. Traditional vægge were built of stone or brick and, in some regions, timber framing with infill. Today, walls are often constructed from concrete blocks, concrete panels, or brick, with insulation and moisture barriers. Interior walls frequently use lightweight constructions such as timber studs with gypsum board (gipsvæg), while exterior walls may feature layered assemblies with insulation, vapor barriers, and cladding or façades.

Performance aspects include thermal insulation, fire resistance, moisture management, and sound attenuation. Walls are designed to meet building codes and safety standards, balancing structural requirements with energy efficiency and acoustic comfort. The choice of wall type influences room layout, daylight access, and ventilation strategies in a building.

Etymology and related terms: væg is cognate with Swedish vägg and other Germanic-language terms for a barrier or enclosure, reflecting its long-standing role in architecture and construction.
