Thermal Performance of Curtain Walling - Calculation of Thermal Transmittance
Also Known As:
The DIN EN ISO 12631 standard specifies a method for calculating the thermal transmittance of curtain walls. This standard covers curtain walls that consist of glazed and/or opaque panels fitted in frames. The calculation takes into account various factors such as the type of glazing (glass or plastic), the number of glazing layers (single or multiple), the presence of low emissivity coating, and the use of air or gas-filled cavities. It also considers the frames, whether they have thermal breaks or not, and the type of material used for the opaque panels, such as metal, glass, or ceramics.
The calculation method also includes the consideration of thermal bridge effects at the connections between the glazed areas, frame areas, and panel areas. However, certain factors are not included in the calculation, such as the effects of solar radiation, heat transfer caused by air leakage, condensation calculations, the effects of shutters, additional heat transfer at corners and edges of the curtain walling, connections to the main building structure, through fixing lugs, and curtain wall systems with integrated heating.
