Unterlattung

Unterlattung is a term with specific meanings within different fields, primarily in construction and surveying. In the context of building and construction, Unterlattung refers to the underlying or supporting layer, often a sub-frame or battens, used to create a space for insulation, ventilation, or to provide a stable surface for attaching a final covering. This is commonly seen in roofing, where a sub-roofing layer or battens are installed beneath the main roofing material to allow for drainage and airflow, preventing moisture buildup. Similarly, in wall construction, Unterlattung can be used to create a cavity for insulation or services before the interior or exterior cladding is applied.

In surveying and engineering, Unterlattung can refer to a foundational or base structure that supports a more complex system. This might involve a supporting grid or frame upon which instruments are mounted or onto which measurements are projected. The purpose is to ensure stability and accuracy for the overlying components or processes. The specific materials and design of the Unterlattung will vary greatly depending on its intended application, ranging from simple wooden battens to intricate metal frameworks. The common thread is its role as a preparatory or foundational element that enables the successful installation and function of the primary structure or system.
