Abstract
The paper covers current trends in the development of facade systems. Modern innovative hinged panels made of glass fiber reinforced concrete and polyurethane foam with integrated clinker products are considered. An analysis of the defects identified during the inspection of the panels was carried out. Possible mechanisms of their damage are described. The most likely cause of damage to clinker products integrated into panels are tensile and shear stresses resulting from differences in temperature deformations of clinker and glass fiber reinforced concrete. An analysis of the stress state of these materials at positive and negative temperatures was performed. The results of experimental studies are presented. Installing a damping layer of deformable material might be the way to compensate the stresses between clinker products and glass fiber reinforced concrete. An analysis of the stress state of the connection of ceramic tiles with polyurethane foam is given. It is shown that due to the significant difference in their temperature deformations, a concentration of shear stresses is observed in the contact zone, resulting in delamination of the tiles. The paper discusses the potential implication of the described panels and their possible further improvement.
