Masonry and masonry products - Methods for determining design thermal values

This European Standard gives procedures for the determination of design thermal values (thermal resistance and/or thermal conductivity) of masonry and masonry products.

Mauerwerk und Mauerwerksprodukte - Verfahren zur Ermittlung von Wärmeschutzrechenwerten

Diese Europäische Norm beschreibt Verfahren zur Ermittlung von Wärmeschutzrechenwerten (Wärme-
durchlasswiderstand und/oder Wärmeleitfähigkeit) für Mauerwerk und Mauerwerksprodukte sowie Ver-
fahren für die Erstprüfung und die Eigenüberwachung von Wärmedämmeigenschaften.
