Insulation board for thermal insulation of the external façades of buildings

摘要

Insulating board for thermal insulation of the external facades of buildings, comprises two layers, where the outer surface of a first layer (1) is determined for installing on the exterior facades, and the outer surface of a second layer (2) serves for applying a plaster. The first layer is thicker than the second layer, and is made of expanded polystyrene granules, which comprises an additive of athermanous materials (3.5-7 wt.%). The second layer is made of expanded polystyrene granules, where the thermal insulation is mostly produced by the first- and the second layer. Insulating board for thermal insulation of the external facades of buildings, comprises two layers, where the outer surface of a first layer (1) is determined for installing on the exterior facades, and the outer surface of a second layer (2) serves for applying a plaster. The first layer is thicker than the second layer, and is made of expanded polystyrene granules, which comprises an additive of athermanous materials (3.5-7 wt.%). The second layer is made of expanded polystyrene granules, where the thermal insulation is mostly produced by the first- and the second layer, which affects zero potential of the insulating board required for the fastening on the exterior facade and for the application of the plaster. The second layer comprises additive of athermanous materials (0.5-4 wt.%) and further organic bright color pigments (0.03-0.3 wt.%), through which the second layer receives a bright color, and where heat rays striking on the second layer are reflected by the surface so that insulating effect is improved and a heating of the insulation is avoided before the application of the plaster on the second layer.
