Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 2 : numerical method for frames

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.

Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 2 : numerical method for frames

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.

Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 2 : numerical method for frames

Le présent document spécifie une méthode et des données d'entrée exigées pour le calcul du coefficient de transmission thermique des profilés de menuiserie ainsi que du coefficient de transmission thermique linéique de leurs jonctions avec le vitrage et les panneaux opaques. Le présent document fournit des critères pour la validation des méthodes numériques utilisées dans ce calcul. Les effets des ponts thermiques entre les profilés de menuiserie et la structure du bâtiment, du rayonnement solaire, du transfert thermique provoqué par les infiltrations d'air, des transferts thermiques tridimensionnels ne sont pas pris en compte.

Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 2 : numerical method for frames

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
