Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 2: Numerical method for frames (ISO 10077-2:2017)
ISO 10077-2:2017 specifies a method and gives reference input data for the calculation of the thermal transmittance of frame profiles and of the linear thermal transmittance of their junction with glazing or opaque panels. The method can also be used to evaluate the thermal resistance of shutter profiles and the thermal characteristics of roller shutter boxes and similar components (e.g. blinds). ISO 10077-2:2017 also gives criteria for the validation of numerical methods used for the calculation. ISO 10077-2:2017 does not include effects of solar radiation, heat transfer caused by air leakage or three-dimensional heat transfer such as pinpoint metallic connections. Thermal bridge effects between the frame and the building structure are not included. NOTE Table 1 in the Introduction shows the relative position of ISO 10077-2:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.
