Objectives and work programme
Modern construction projects show an increasing tendency to focus on purist architecture with homogeneous and clearly formulated surfaces and edges in facade design. In these designs, large-scale facade elements made of high-quality materials, such as glass, are being used more frequently. In doing so, gradation is avoided in the facade, as is the use of any additional visible components or connections. This trend is also being observed increasingly in the designs for balcony balustrades, whereby many of these components are classed as unregulated products by construction regulations and therefore require more testing and research. The intention is therefore to develop a new, fall-safe balcony balustrade that allows modern, high-quality and homogeneous facades to be integrated easily. The balustrade is to be a hybrid structure consisting of a support material with glass panels attached by way of full-surface adhesive bonding. The bonding between the materials is planned to serve as a load-bearing bond, without any additional mechanical safeguards, and without a separate handrail. The main focus is on the material selection for the support panel when used in connection with glass and on the durability of the adhesive bond when exposed to environmental influences and mechanical stress. Furthermore, the structure must ensure sufficient fall protection, a sufficient residual load-bearing capacity in the case of glass breakage, and protection from any falling glass splinters. This new type of balcony balustrade offers the highest level of clarity in terms of forms and lines thanks to the glass faces, the lack of an additional handrail and the non-visible support structure, and therefore meets the requirements of minimalistic architecture. With the use of large-format elements and a modular structure for the hybrid balustrade, it should also be possible to custom design the balustrade system to suit any balcony or terrace floor plan. Moreover, coloured coatings on the glass panels can change the aesthetic of the balustrade, which can be adapted to suit the individual needs of clients and architects.
