Murskikt

Murskikt, literally "masonry layer" in Swedish, denotes the masonry layer within a wall, formed from bricks, blocks, or stones bound with mortar or cementitious binder. It is a key element in many construction systems, serving either as a load-bearing wall or as a decorative and protective veneer attached to a structural frame.

In exterior walls, murskikt can take several forms. A solid masonry wall uses a single wythe of masonry units. A cavity wall places two masonry wythes with a drained or damp-proof cavity between them, improving thermal performance and moisture management. In veneer systems, a non-load-bearing masonry facing is supported by a separate structural backing, such as timber or steel framing.

Materials and construction are dictated by local climate, performance requirements, and architectural goals. Common masonry units include brick, concrete block, and natural stone. Mortar types range from lime-based for historic or high-flexibility needs to cementitious mixes for modern work. Joints and bonding patterns influence strength, durability, and appearance. Walls may include insulation, damp-proof courses, flashing, and air barriers to manage moisture and thermal bridging.

Functions of a murskikt include structural support, thermal mass, fire resistance, and acoustic performance. Durability depends on proper detailing at openings, joints, and interfaces with other materials.

In practice, designers select a murskikt configuration to balance load, moisture control, insulation, and aesthetics, often integrating it with other wall systems to meet energy and safety standards.
