Innovative, flame-retardant PU insulation systems from puren
were selected as the optimal solution for this energetically and economically demanding construction project. puren gmbh has been our customer and partner for a long time. The company is one of the pioneers in the field of rigid polyurethane foam technology.
In order to be able to achieve a high standard of energy efficiency and affordable housing at the same time, particularly efficient use of valuable resources is required. Land for building is scarce and increasingly expensive. This is precisely where PU high-performance insulating materials can come in, because they provide a particularly high level of thermal insulation without sacrificing valuable living space. This improves the ratio of living space to construction costs and can thus make an important contribution to affordable housing.
Innovative thermal insulation made of polyurethane (PU) has a very low lambda value. As a result, puren is able to deliver high-performance insulation in a minimal footprint. This ability makes PU an effective and cost-efficient insulating material both for new buildings and the renovation of existing buildings. The big advantage of PU is that the high efficiency house standards are possible with relatively slim facade and ceiling constructions, because PU as a high-performance insulating material insulates particularly well. This allows valuable living space to be preserved. Compared to other, traditional insulation materials, this saves a lot of space and thus money, which represents a real gain in living space.
In this particular case, the PU insulation panels were installed on the ceiling of the underground parking garage. This way, space could be saved in the structure height, which had a positive effect on the cost efficiency of the building, since, for example, reduced excavation work was required as well as less building material such as concrete for the structure for the walls.
Insulating the facades with PU insulation panels for ETICS (external thermal insulation composite systems) also had a strong effect. Thanks to a consistent optimization of space already in the planning phase, it was possible to save a lot of space in the thickness of the exterior walls with the slim facade construction. As a result, the investor was able to achieve a gain in living space totaling three more apartments in this project, which would not have been possible with any other conventional insulation material at this level of overall efficiency.
In addition to the underground parking garage ceiling insulation and the ETICS facade insulation, other PU innovations were used in this project. For example, the flame-retardant insulation for the roof as well as the special roof edge constructions made of PU structural insulation materials not only increase energy efficiency but also the safety of the buildings due to a thermal bridge-free roof edge closure.
PU insulation materials are recyclable and can be returned to the material cycle in line with the circular economy.
