NF EN ISO 10077-1
Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 1 : general
ISO 10077-1:2006 specifies methods for the calculation of the thermal transmittance of windows and pedestrian doors consisting of glazed and/or or opaque panels fitted in a frame, with and without shutters. ISO 10077-1:2006 allows for the following: different types of glazing (glass or plastic; single or multiple glazing; with or without low emissivity coatings, and with spaces filled with air or other gases);opaque panels within the window or door;various types of frames (wood, plastic, metallic with and without thermal barrier, metallic with pinpoint metallic connections or any combination of materials);where appropriate, the additional thermal resistance introduced by different types of closed shutter, depending on their air permeability. The thermal transmittance of roof windows and other projecting windows can be calculated using ISO 10077-1:2006, provided that the thermal transmittance of their frame sections is determined by measurement or by numerical calculation. Default values for glazing, frames and shutters are given in ISO 10077-1:2006. Thermal bridge effects at the rebate or joint between the window or door frame and the rest of the building envelope are excluded from the calculation. The calculation also does not include effects of solar radiation, heat transfer caused by air leakage, calculation of condensation, ventilation of air spaces in double and coupled windows and surrounding parts of an oriel window. ISO 10077-1:2006 does not apply to curtain walls and other structural glazing and industrial, commercial and garage doors.

Le présent document spécifie des méthodes de calcul du coefficient de transmission thermique des fenêtres et portes composées de panneaux vitrés ou opaques montés dans un dormant avec et sans fermetures. Des valeurs par défaut des vitrages, dormants et fermetures sont données dans des annexes. Les effets de pont thermique à la contrefeuillure ou au joint entre le dormant de la fenêtre ou de la porte et le reste de l'enveloppe du bâtiment sont exclus du calcul. Le présent document ne couvre pas les murs-rideaux et les lucarnes.
