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. |
