Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 2: Numerical method for frames (ISO 10077-2:2012)
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.
Wärmetechnisches Verhalten von Fenstern, Türen und Abschlüssen - Berechnung des Wärmedurchgangskoeffizienten - Teil 2: Numerisches Verfahren für Rahmen (ISO 10077-2:2012)
Dieser Teil der ISO 10077 legt ein Verfahren und Bezugseingabedaten für die Berechnung des
Wärmedurchgangskoeffizienten von Rahmenprofilen und des längenbezogenen Wärmedurchgangskoeffizienten
ihrer Verbindungsstellen mit Verglasungen oder opaken Füllungen fest.
Das Verfahren kann weiterhin zur Bewertung des Wärmedurchlasswiderstands von Rollladenprofilen und der
thermischen Eigenschaften von Rollladenkästen und ähnlichen Bauteilen (z. B. Jalousien) verwendet werden.
Dieser Teil der ISO 10077 beschreibt außerdem Kriterien, die zur Validierung von numerischen Verfahren für
die Berechnung dienen.
Dieser Teil der ISO 10077 berücksichtigt weder die Einflüsse der Sonneneinstrahlung, noch die
Wärmeübertragung infolge von Luftdurchlässigkeit, noch die dreidimensionale Wärmeübertragung, wie z. B.
durch punktförmige metallische Verbindungen. Wärmebrückenwirkungen zwischen Rahmen und Baukörper
sind ebenfalls nicht berücksichtigt.
Performance thermique des fenêtres, portes et fermetures - Calcul du coefficient de transmission thermique - Partie 2: Méthode numérique pour les encadrements (ISO 10077-2:2012)
L'ISO 10077-2:2012 donne une méthode et des données d'entrée pour le calcul du coefficient de transmission thermique des encadrements et du coefficient de transmission thermique linéique de leurs jonctions avec les vitrages ou les panneaux opaques.
Cette méthode peut également être utilisée pour évaluer la résistance thermique d'encadrements de fermetures et les caractéristiques thermiques de coffres de volet roulant et de composants similaires (par exemple stores).
L'ISO 10077-2:2012 fournit également des critères pour la validation des méthodes numériques utilisées dans ce calcul.
L'ISO 10077-2:2012 ne couvre pas les effets du rayonnement solaire ni le transfert thermique provoqué par des infiltrations d'air ou les transferts thermiques tridimensionnels créés par exemple par des liaisons métalliques ponctuelles. Les effets des ponts thermiques entre les encadrements et la structure du bâtiment ne sont pas pris en compte.
Toplotne lastnosti oken, vrat in polken - Izračun toplotne prehodnosti - 2. del: Računska metoda za okvirje (ISO 10077-2:2012)
Ta evropski standard določa metodo in podaja referenčne vhodne podatke za izračun toplotne prehodnosti profilov okvirjev in linearne toplotne prehodnosti njihovega spoja z zasteklitvijo ali prosojnimi ploščami.
Metodo je mogoče uporabiti tudi za oceno toplotne upornosti profilov polken in toplotnih značilnosti roletnih škatel.
Ta evropski standard določa tudi merila za ovrednotenje računskih metod za izračun.
Ta evropski standard ne zajema učinkov sončnega sevanja, prenosa toplote zaradi puščanja zraka ali tridimenzionalnega prenosa toplote, kot so točkaste kovinske povezave. Učinki toplotnih mostov med okvirjem in strukturo stavbe niso zajeti.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10077-2 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 2, Calculation methods, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 89, Thermal performance of buildings and building components,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This International Standard is one of a series of standards on methods for the design and evaluation of the
thermal performance of building equipment and industrial installations.
This second edition cancels and replaces the first edition (ISO 10077-2:2003), which has been technically
revised. The main changes compared to the previous edition are given in the following table:
Clause Changes
5.1 Clarified use of measured data.
5.4 Added calculation rules for roller shutter boxes and added new figure.
5.5 Added calculation rules for extensions of window frame profiles and new added figure.
Annex A Added Table A.2 — Thermal conductivity of timber species.
Annex A Added Table A.3 — Typical emissivities of metallic surfaces.
Annex B Added Table B.2 for roller shutter boxes.
C.2 Added calculation rules for the combination of frame constructions with insulating
glazing units (IGU) and Figure C.3 showing a representative metal spacer incorporated
in an IGU.
Annex D Updated Figures D.1 to D.10 for frame sections.
ISO 10077 consists of the following parts, under the general title Thermal performance of windows, doors and
shutters — Calculation of thermal transmittance:
