![]() ![]() If, however, you look at a vertically perforated brick with its complex web geometry as well as possible insulating material filling of the perforated chambers, generally it is necessary to talk about the resulting thermal conductivity to differentiate it from the pure material thermal conductivity. The key factor in the heat transmission in a brick body are thermal conduction via the solid structure and the pore air.įor these reasons, it is common and completely reasonable in the case of these building materials to talk generally about thermal conductivity as a material property. brick body, thermal radiation and convection via the pore structure can be neglected. For construction materials with medium to high density, e.g. For such construction materials, besides the thermal conduction via the pure solid body structure, the gas phase as well as liquid water in the pores, thermal radiation between the surfaces of the pores and thermal convection via the air in the pores also occur. Especially insulating materials, but also mineral construction materials like a brick body or organic construction materials like wood have a more or less complex pore structure. With regard to thermal conductivity in construction materials, then, strictly speaking, it refers to a mixed form of different heat transfer mechanisms. The usual symbol for this is the small Greek letter λ (lambda) with the unit J/(m It specifies the heat flow in joules that passes through a 1-m² large and 1-m-thick layer of a certain material. Thermal conductivity is a temperature-dependent, material-specific value of a pure solid body, a pure liquid or a pure gas. This article addresses the construction-related physical property of thermal conductivity as well as the numerical and measurement-based possibilities for its determination.ġ Basic principles concerning thermal conductivity from the Brick and Tile Research Institute Essen was published on “Application of numerical simulations for investigation and improvement of the acoustic behaviour of vertically perforated bricks”.
