(FR) ELEMENT ISOLANT
Abstract
(DE)
Die Erfindung betrifft ein Dämmstoffelement aus Mineralfasern, die mit einem Bindemittel und/oder durch mechanische Bearbeitung, wie Vernadelung, Verfilzung oder dergleichen miteinander verbunden sind, bei welchem zumindest eine Mineralfaserschicht und zumindest eine Oberflächenschicht vorgesehen sind, wobei die Oberflächenschicht eine gegenüber der Mineralfaserschicht zumindest in Teilbereichen erhöhte Rohdichte aufweist. Ein in einfacher Weise verarbeitbares und beim Rückbau Recyclingprozessen zuführbares Dämmstoffelement wird dadurch geschaffen, daß zumindest auf der Oberflächenschicht mit der erhöhten Rohdichte eine Kleber- oder Putz-affine Beschichtung aufgebracht ist, die eine von der Mineralfaserschicht abweichende Farbgebung hat.
(EN)
The invention concerns an insulating element made out of mineral fibers, which are bounded together with a fixing agent and/or by mechanical processing such as needling, felting or the like. The element has at least one mineral fiber layer and at least one surface layer. The surface layer presents a bigger apparent density at least in certain parts as compared to the mineral fiber layer. The invention seeks to create an insulating element that can be easily processed and recycled when dismantled. To this end, a coating having affinity with the bonding agent or the plastering agent is applied at least on the surface layer showing greater apparent density. Said coating has a different coloring than the mineral fiber layer.
(FR)
L'invention concerne un élément isolant en fibres minérales liées entre elles avec un liant et/ou par un traitement mécanique, par ex. aiguilletage, feutrage ou similaire. Au moins une couche de fibres minérales et au moins une couche superficielle sont prévues dans cet élément, la couche superficielle présentant une masse volumique apparente supérieure, au moins en partie, par rapport à la couche de fibres minérales. L'invention vise à créer un élément isolant pouvant être mis en oeuvre de façon simple et pouvant être acheminé vers des processus de recyclage lors du démontage. A cet effet, un revêtement présentant une affinité avec une colle ou un enduit est appliqué au moins sur la surface superficielle possédant la masse volumique apparente élevée, ledit revêtement présentant une teinte différente de la couche de fibres minérales.
