Glass in building - Determination of thermal transmittance (U value) - Calculation method

This European Standard specifies a calculation method to determine the thermal transmittance of glazing with flat and parallel surfaces. This European Standard applies to uncoated glass (including glass with structured surfaces, e.g. patterned glass), coated glass and materials not transparent in the far infrared which is the case for soda lime glass products, borosilicate glass and glass ceramic. It applies also to multiple glazing comprising such glasses and/or materials.

Glas im Bauwesen - Bestimmung des Wärmedurchgangskoeffizienten (U-Wert) - Berechnungsverfahren

Diese Europäische Norm enthält ein Berechnungsverfahren zur Bestimmung des Wärmedurchgangskoeffizienten von Verglasungen mit ebenen und parallelen Oberflächen. Die vorliegende Europäische Norm gilt für unbeschichtetes Glas (einschließlich von Glas mit strukturierter Oberfläche, z.B. Ornamentglas), beschichtetes Glas und für Materialien, die im fernen Infrarotbereich undurchlässig sind, z.B. Produkte aus Natron-Kalk-Glas, Borosilicatglas und Glaskeramik. Sie gilt ebenfalls für Mehrfachverglasungen aus derartigen Gläsern und/oder Materialien.

Verre dans la construction - Détermination du coefficient de transmission thermique, U - Méthode de calcul

La présente norme européenne présente une méthode de calcul du coefficient de transmission thermique des vitrages à surfaces planes et parallèles. Cette norme européenne est applicable au verre sans couche (y compris le verre avec surfaces structurées, par exemple le verre imprimé), au verre recouvert d'une couche et aux matériaux opaques au rayonnement infrarouge de grande longueur d'onde, ce qui est le cas pour les produits verriers sodo-calciques, le verre borosilicate et les vitrocéramiques. Elle est également applicable aux vitrages multiples qui comportent de tels verres et/ou matériaux.
