Facade insulation

There are different variants for facade insulation: exterior, interior and core insulation. In the case of buildings that are not listed as protected objects, exterior insulation is usually applied, whereby there are the following two methods: the compact facade (also called external thermal insulation composite system or ETICS) and the ventilated curtain facade. With a compact facade, the thermal insulation boards are glued directly to the existing façade from the outside. Then a reinforcement layer and finally an external plaster are applied to it. In the case of the ventilated curtain facade, the insulation panels are also glued directly to the existing facade, but the new facade covering is erected with a scaffolding system with some distance to the thermal insulation. This scaffolding (also called substructure) is attached to the old facade and supports the new facade covering. A ventilated curtain facade keeps weather-related influences away from the insulation and ensures good air circulation and moisture removal. For this reason, a ventilated curtain facade has a significantly longer service life than a compact facade. Further advantages are the design freedom in the facade covering and the fact that renewable insulation materials such as wood fibre can also be used (which leads to lower embodied emissions). The only disadvantage compared to the compact facade is the higher costs.
