Sažetak
Light steel framed (LSF) panels are increasingly being used as loadbearing and non-loadbearing elements as an alternative to traditional masonry and concrete structures. They are widely used in the U.S., Australia and Japan, while their use is increasing in Europe. Some advantages offered by LSF panels compared to masonry and concrete elements are low weight, high mechanical strength, higher construction speed, possibility of recycling and reuse, high architectural flexibility, easy prefabrication that allows modular construction, precise tolerances, etc. However, among the major disadvantages is the high thermal conductivity of steel elements, which can lead to significant thermal bridging and somewhat lower thermal mass. Based on the numerous potential advantages and considering the disadvantages, a new innovative LSF panel is proposed within the research project KLIK PANEL. The innovative panel consists of sheathing boards, steel studs and tracks while the cavity is completely filled with polymer foam (PUR), which structurally connects the components into a single coherent product. To further prevent cold bridges, thermal breaks in form of spacers are used. Since the polymer foam insulation is highly flammable, the fire performance of such panel is questionable. The main objective of this preliminary study is to determine the appropriate sheathing to prevent the temperature leading to ignition of the polymer foam. Currently, there are a variety of sheathing options that provide high fire resistance. To determine the best option, 2D numerical models were created using different sheathing boards (gypsum plasterboards, magnesium oxide boards, magnesium sulphate boards, calcium silicate boards, fiber cement boards, perlite boards) to study the temperature development through the structure and determine the temperature that leads to ignition of the polymer foam.
