DESCRIPTION

BS EN ISO 10077-2:2017


This standard BS EN ISO 10077-2:2017 Thermal performance of windows, doors and shutters. Calculation of thermal transmittance is classified in these ICS categories:
  • 91.060.50 Doors and windows
  • 91.120.10 Thermal insulation of buildings

This document 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).

This document also gives criteria for the validation of numerical methods used for the calculation.

This document 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 this document within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.
