flerlaget

Flerlaget is a term used in Norwegian and Swedish to describe something that consists of several distinct layers. The word combines fler, meaning “multiple,” with laget, the definite form of lag or layer. In general usage, flerlaget can function as both an adjective (flerlaget, flerlagrade) and a noun referring to a multilayer structure.

In science, engineering, and industry, flerlaget describes materials, coatings, or assemblies engineered as multiple layers to achieve specific properties. Multilayer coatings on tools or glass can improve hardness, wear resistance, or optical performance. In electronics, flerlagers systems refer to multilayer printed circuit boards with several conductive and dielectric layers. In geology, the term denotes stratified rock or sediment sequences with distinct layers. In textiles and packaging, multilayer laminates combine layers of fabric, film, or foil to enhance strength, barrier properties, or insulation. In architecture and construction, flerlagers envelopes or walls incorporate multiple layers for thermal insulation, moisture control, and acoustics.

Origin and usage notes: The term is common in Norwegian and Swedish technical literature and translates to “multilayer” in English. Spelling and inflection vary by language, with Norwegian examples including flerlaget (the multilayer) and flerlagret (multilayered), and Swedish forms such as flerlagrad or flerlagrade. The concept is applied across disciplines to describe complex, layered structures designed to optimize performance or functionality.
