Insulation systems for covering facades of buildings

Abstract

The invention relates to an improved insulation system for covering building facades, consisting of at least one insulation element (3), at least one mechanical fastener (4) and a plastering system (5), the mechanical fastener ( 4) Fixing the insulating element (3) to the façade (2) of the building, the plastering system (5) is arranged on the outer surface of the insulating element (3), whereby the insulating element has at least a first layer and second layer; whereby the first layer directed towards the façade has a lower bulk density than the second layer; and thus at least one layer is made of mineral fibers, especially rock wool fibers and a binder, or is made of Styrofoam is especially made of expanded polystyrene (EPS). In order to achieve an insulation system with very good insulation properties, which can be manufactured at low cost and which can be fixed to the building facade without incurring high labor costs, the insulation element (3) has a second Three layers (10), the third layer (10) having a higher bulk density than the second layer (9) and the third layer (10) in the absence of any surface primers, coatings and / or additives The bottom has a high receptivity and / or adhesion to the plastering system (5).

Description

technical field [0001] The invention relates to an insulation system for covering the facade of a building, the insulation system consisting of at least one insulation element, at least one mechanical fastener and a plastering system, the fastener fastening the insulation element to the facade of the building surface, the plastering system is arranged on the outer surface of the insulating element. Said system is also known as External Thermal Isolation Composite System (ETICS). Background technique [0002] The insulating element has at least a first layer and a second layer connected to each other, wherein the first layer directed towards the facade has a lower bulk density than the second layer and wherein at least one layer is made of mineral fibers, especially rock wool fibers and adhesive, or foamed plastic, especially expanded polystyrene (EPS). [0003] Such isolation systems are well known in the art. In modern roof and facade construction it is common to use min...

AI Technical Summary

Problems solved by technology

The use of thick plies has the disadvantage that the weight of such insulation panels requires many mechanical fasteners to secure them to the façade

The use of insulation panels of great thickness along with the large number of mechanical fasteners increases the price of such insulation systems, ie material and labor costs

Moreover, such high-density mineral fiber boards are known to provide very poor acceptance for rendering systems, which is why many attempts have been made in the prior art to isolate the surface by applying different surface primers, coatings and / or additives. The reason for the improved receptivity of the component surface
