Holrými

Holrými is an Icelandic term that denotes a hollow space or cavity. It is formed from the words hol meaning hole and rými meaning space, and it is used across disciplines to refer to an empty region enclosed within or between solid matter. In general, holrými describes a void or empty volume rather than a filled space.

In architecture and construction, holrými refers to cavities within structures, such as air gaps behind walls, voids in floors, or hollow sections designed for insulation, wiring, or plumbing. These hollow regions influence a building’s thermal performance, sound insulation, and structural behavior.

In geology and speleology, holrými can describe natural voids in rock, including caves, chambers, or fractures that have been created by processes such as dissolution, weathering, or tectonic movement. The size and connectivity of these voids determine groundwater flow, mineralization, and cave aesthetics.

In biology and anatomy, holrými is sometimes used to denote hollow spaces within organisms or organs, such as body cavities. Although terminology can vary by subfield, the concept centers on spaces that accommodate fluids, air, or other tissues.

In materials science, holrými relates to porosity and voids within foams, composites, or porous media. The presence and distribution of hollows affect properties like strength, density, thermal conductivity, and acoustics.
