ISO 10077-2:2011规定了一种方法，并提供了用于计算框架轮廓的热透射率和其与玻璃或不透明面板的接合点的线性热透射率的参考输入数据。 该方法还可用于评估快门轮廓的热阻和卷帘箱和类似部件（例如百叶窗）的热特性。 ISO 10077-2:2011也为验证用于计算的数值方法提供了标准。 ISO 10077-2:2011不包括太阳辐射的影响，由漏气引起的热传导或三维传热，如针尖金属连接。不包括框架和建筑结构之间的热桥效应

ISO 10077-2:2011 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 10077-2:2011 also gives criteria for the validation of numerical methods used for the calculation. ISO 10077-2:2011 does not include effects of solar radiation, heat transfer caused by air leakage or three‑dimensional heat transfer such as pin point metallic connections. Thermal bridge effects between the frame and the building structure are not included.
