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.
Toplotnoizolacijski proizvodi za stavbe - Odsevni izolacijski proizvodi - Ugotavljanje nazivnih toplotnih lastnosti
V tem evropskem standardu je opisan sklop postopkov za uporabo obstoječih standardiziranih preskusov CEN ali ISO in metod za izračun za ugotavljanje nazivnih toplotnih lastnosti odsevnih izolacijskih proizvodov. Ta evropski standard podpira obstoječe metode preskušanja CEN ali ISO in jih ne nadomešča.
Ta evropski standard se uporablja za katere koli toplotnoizolacijske proizvode, pri katerih del zahtevanih toplotnih lastnosti izhaja iz prisotnosti enega ali več odsevnih površin ali površin nizke emisivnosti skupaj s povezanimi zračnimi prostori. Ne nadomešča obstoječih postopkov za določanje toplotnih lastnosti proizvodov, ki so že zajeti v obstoječem harmoniziranem standardu za proizvod, pri čemer deklarirana vrednost teh proizvodov ne vključuje posebej nobenih določil, ki jih je mogoče pripisati emisivnosti premaza.

Product type is defined solely for the purpose of selecting the most appropriate test method (product type number does not refer to a generic species of product). Together with 4.2, 4.3 and 4.4, the flow charts in Annexes A, B and C shall be followed in assigning a given product to a product type. In 4.2, 4.3 and 4.4, the product type is determined by reference to its compressibility or otherwise to achieve flat parallel surfaces. This implies the removal of measurable air-gaps between the specimen and the hot and cold plates of the test apparatus whilst not unduly reducing the overall thickness of the specimen to be tested. When using the weighted plate method from EN 823:1994 there shall be no residual air spaces between the weighted plate and the specimen surface. The weight of plate used for the thickness measurement shall be the lowest of either plate sufficient to eliminate air gaps. The thickness measured under the chosen plate shall be the thickness subsequently used for the measurement of the core thermal resistance and given in the test report. 4.2 Product Type 1 A product shall be classified as Type 1 when it has a regular geometry with parallel faces or is compressible so that the product can be contained between the hot and cold plates of the apparatus without significantly changing its core thermal properties. This is achieved when its surfaces are smooth and flat with no discernible depth of pattern or indentation. SIST EN 16012:2012+A1:2015
Key 1 insulation core 2 low emissivity surface or surfaces NOTE The emissivity of each of the outer surfaces can be different or the product can be faced on only one side. Figure 1 — Example of insulation material with reflective facing on each side 4.3 Product Type 2 A product shall be classified as Type 2 when it has a regular geometry with parallel faces or is compressible so that the product can be contained between the test apparatus hot and cold plates without changing its core thermal properties. The surface or surfaces shall not be flat and smooth and can have indentations of less than 5 mm depth when measured using the pin and plate described in EN 823:1994, subclause B.1, or an alternative method with at least the same level of accuracy. The pin shall be placed in the lowest point of any indentation but shall not pierce the surface. NOTE If the indentations are 5 mm or greater, it is product Type 3. EXAMPLES Including, but not limited to, some types of bubble foil insulation with reflective surfaces (see Figure 2).
Key 1 air filled plastic bubbles 2 reflective surface(s) Figure 2 — Example of bubble foil insulation with reflective surfaces 4.4 Product Type 3 A product shall be classified as Type 3 when it has irregular thickness geometry, does not have flat parallel faces, or cannot be compressed to produce flat and parallel faces without changing its core thermal properties. Product Type 3 shall not be measured in a guarded hot plate or heat flow meter apparatus. SIST EN 16012:2012+A1:2015
Key 1 insulation layer(s) between foil – such as foam or wadding 2 welded or stitched fabrication feature 3 low emissivity external surface or surfaces 4 intermediate layers of foil Figure 3 – Example of stitched multi-foil insulation 4.5 Product Type 4 Product Type 4 is a thin film or sheet, less than 2 mm thickness, used singly or in multiple layers, which makes use of a low emissivity surface to increase the thermal resistance of adjacent or enclosed air space(s), but which has no significant thermal resistance of its own. See Figure 4.

The article discusses EN 16012:2012+A1:2015, a European Standard that outlines procedures for determining the declared thermal performance of reflective insulation products. The standard utilizes existing standardized CEN or ISO test and calculation methods and supports, rather than replaces, existing CEN or ISO test methods. It applies to any thermal insulation product that incorporates reflective or low emissivity surfaces with airspace(s) and does not replace procedures for products covered by an existing harmonized product standard, unless the product's declared value includes claims related to emissivity.
