Thermal insulation for buildings - Reflective insulation products - Determination of the declared thermal performance
This European Standard describes a set of procedures for using existing standardized CEN or ISO test and calculation methods to determine the declared thermal performance of reflective insulation products. This European Standard supports and does not replace existing CEN or ISO test methods.
This European Standard applies to any thermal insulation product that derives a proportion of its claimed thermal properties from the presence of one or more reflective or low emissivity surfaces together with any associated airspace(s). It does not replace the existing procedures for the determination of the thermal performance of products already covered by an existing harmonized product standard where the declared value of these products does not specifically include any claims attributable to the emissivity of the facing.
Wärmedämmstoffe für Gebäude - Reflektierende Wärmedämm-Produkte - Bestimmung der Nennwerte der wärmetechnischen Eigenschaften
Diese Europäische Norm beschreibt eine Reihe von Verfahren zur Anwendung bereits bestehender genormter CEN- oder ISO-Prüf- und Berechnungsverfahren, mit deren Hilfe die Nennwerte der wärmetechnischen Eigenschaften von reflektierenden Wärmedämm-Produkten bestimmt werden können. Diese Norm unterstützt bestehende CEN- bzw. ISO-Prüfverfahren und ist nicht dafür vorgesehen, diese zu ersetzen. Diese Europäische Norm gilt für alle Wärmedämmprodukte, bei denen die beanspruchten wärmetechnischen Eigenschaften zu einem beträchtlichen Teil durch das Vorliegen einer oder mehrerer reflektierenden/r oder niedrigemittierenden/r Oberfläche(n) und dem/r zugehörigen Luftraum/räume erreicht werden. Sie stellt keinen Ersatz für die bestehenden Verfahren zur Bestimmung der wärmetechnischen Eigenschaften von Produkten dar, die bereits durch eine bestehende harmonisierte Produktnorm abgedeckt sind, und bei denen die Nennwerte dieser Produkte keine spezifischen Ansprüche abdecken, die sich aus dem Emissionsgrad der Deckschicht ergeben.
Isolation thermique des bâtiments - Produits d’isolation réfléchissants - Détermination de la performance thermique déclarée
La présente Norme européenne décrit un ensemble de modes opératoires pour l'utilisation de méthodes existantes d'essai et de calcul normalisées par le CEN et l'ISO pour déterminer la performance thermique déclarée des produits d'isolation réfléchissants. La présente Norme européenne vient à l'appui des méthodes d'essai CEN et ISO existantes, mais elle n'est pas destinée à les remplacer.
La présente Norme européenne s'applique à tout produit d'isolation thermique dont une partie des propriétés thermiques déclarées est liée à la présence d'une ou plusieurs surfaces réfléchissantes ou à faible émissivité ainsi qu'à toute lame d'air associée. Elle ne remplace pas les modes opératoires existants pour la détermination de la performance thermique des produits déjà couverts par une norme de produit harmonisée existante lorsque la valeur déclarée de ces produits n'inclut pas spécifiquement des propriétés déclarées attribuables à l'émissivité des parements.

Since all conventional thermal insulation products declare their thermal performance on the basis of the value to be expected over a reasonable working life, this is also addressed in a limited manner in this standard in the assessment of emissivity of the surface(s) of reflective insulation. In the absence of any quantified and certified data on the aged performance of a facing over a normal lifetime for a building material, the ageing of the low emissivity surface is assessed by use of an accelerated ageing procedure.
How the thermal properties of insulation materials that utilize reflective surfaces are determined will depend on the form in which they are sold and how they are intended to be used. This standard describes a number of different approaches which can be utilized and specifies which approach to use for the different types of product. Where a product is already subject to a product specification that describes procedures for the measurement of the aged 90/90 fractile thermal conductivity or thermal resistance of the core insulation material, the following guidance should only be used to determine the component of its thermal performance that depends on the emissivity of its external faces. However, it should be remembered that the declared value is only the first step, giving comparative performance values under specified conditions, and the design value can give more information for use by the designer in specific applications, especially under different climatic conditions.
