λ in SI unit: [W/(m·K)] or British Thermal Units: [Btu in/(h·ft2·°F)] R in SI unit [(m2·K/W)] or British Thermal Units: [(h·ft2·°F)/Btu] The heat flow through a brick wall or a window part is defined by the U-value in [W/(m²K)]. The lower the U-value, the better the insulation property of the respective part of the building and therefore the greater the energy efficiency of the building as a whole. This illustrates the need to determine the U-value for all parts of the building envelope, such as brick walls, facades, windows and doors. Stationary methods are usually preferred for larger...

TDW 4040 Test Chamber for Determining the Stationary Heat Transfer Properties with a Heat Flow Meter in Accordance with DIN EN 1934 The compact test chamber TDW 4040 was designed for testing brickwork (such as brick, lime sand brick, concrete, or aerated concrete) and basically simulates the temperature and the natural convection inside and outside a building. Optionally, the humidity level in the two sections of the chamber can be set as needed. The HotBox software at the measurement and control units is used to set all parameters, as well as for complete data logging, detailed analysis...
