underlægger

Underlægger is a Danish term that translates to "underlayer" or "base layer" in English. It is commonly used in textiles and construction. In the context of clothing, an underlægger refers to a garment worn directly against the skin as the first layer of an outfit. This layer is designed to provide warmth, wick away moisture, or offer a smooth surface beneath outer garments. Examples include thermal underwear, base layers for sports, or slips worn under dresses.

In construction, underlægger can refer to a material placed beneath another to provide support, insulation, or protection. This could be a sub-base layer for a road, a layer of insulation beneath flooring, or a protective membrane under roofing materials. The specific function of the underlægger in construction depends on the overall structure and its environmental conditions. The concept emphasizes the importance of a foundational or intermediary component that enhances the performance or durability of the primary element it supports.
