ISOPRO® Introduction Introduction Energy saving regulations (EnEv) stipulate that structures must be planned and executed such that thermal bridges are either avoided or reduced. The technically approved ISOPRO® thermal insulation elements are ideally suited for this purpose. The connecting elements consist of an insulating Neopor® body with structural rebar inserts to reliably transfer forces. The combination of B500B and B500NR rebars reliably eradicates corrosion problems and reduces heat flow within the rebars to a minimum. With an insulation thickness of 80  mm, ISOPRO® solves thermal bridge...

Building physics – thermal insulation The thermal bridge When calculating a building's heat demand for the verification required by the energy saving regulations (EnEV), thermal bridges must be taken into account. Thermal bridges are weak spots in the building's thermal transfer envelope, which lead to locally enhanced heat losses compared to standard components. Geometrical thermal bridges are differentiated on one side, where the heat flow from the inner surface is juxtaposed with a larger external surface (e.g. external building corners), and on the other side by material thermal bridges, where...

Building physics – thermal insulation Effects of thermal bridges Thermal bridges are engineering weak spots in the structure. A thermal bridge displays a particularly high heat flux, so that the surface temperature on the inside of external components drops rapidly due to the locally enhanced heat loss. Effect of a thermal bridge During the heating period in particular, this leads to the temperature falling below the dew point, and surface or capillary condensation forming at these points. The foundation for the formation and growth of mould is laid. Consequences ■ Increase in rel. humidity Local...

Building physics – thermal insulation Humidity The proportion of water vapour in the gaseous mixture (in this case: in a room) is referred to as the humidity. The commonest measure of humidity is relative humidity, given in percent and reflecting the ratio of the current water vapour content of the air in a room to the saturation level. At lower temperatures the ability to store water is lower than at higher temperatures. For example, a cubic metre of air at 10 °C can accept a maximum of 9.41 g of water. The same volume of air at 30  °C can accept up to 30.38  g of water. We refer to the saturation...

Building physics – thermal insulation Three-dimensional thermal bridge analysis in accordance with DIN EN ISO 10211 In order to meet a building's energy and climate quality demands, it is necessary to determine the transmission heat losses. This comprises: ■ determination of the U values of standard components; ■ determination of the losses through linear and point thermal bridges. Thermal bridges are classified as follows: Thermal bridge Analysis method Common linear thermal bridges e.g. external wall corners, eaves flashing Thermal transmittance per unit length ψ [W/(mK)] Special linear thermal...
