Sidekerros

Sidekerros is a Finnish term that translates to “side layer” and is used in several fields to denote a layer that lies to the side of a main layer or component. The precise meaning depends on the domain, but the common thread is that the term identifies an auxiliary layer that influences the properties or behavior of the system.

In geology and soil science, a sidekerros refers to a lateral stratigraphic layer that extends beside a primary bed. It can reflect lateral facies changes, variations in sediment supply, or post-depositional deformation. Sidekerros correlations assist in mapping the spatial extent of deposits and understanding sedimentology.

In construction and materials science, sidekerros can denote a protective or finishing layer applied to the side surfaces of a panel, board, or composite. It contributes to environmental resistance, durability, or aesthetics, and is often manufactured as a veneer, coating, or skin that adheres to the side of the main core material.

In manufacturing and packaging, the term may describe an outer skin or coating applied to the side surfaces of a product, serving as a barrier, decorative layer, or protective finish.

The concept shares roots in the Finnish kerros meaning layer. Because sidekerros is used across disciplines, its exact definition remains context-specific, and it is best interpreted from accompanying technical definitions or drawings in a given field.
