Fire safety of building is a complex process, which main target is to maintain the highest level of protection of life, the environment and property. These measures also include transfers through fire separation structures. My goal was to comparise the quality of these fire troughs in our country and after all to compare it with abroad too. Another goal was to give an example from real life, explore a particular company where such systems are made. We dealt with the methodology according to current legislation. The results of the selected company confirmed that the transfers were solved and made in accordance with the design documentation of the building and meet all the parameters stated on the label according to the legislation. Furthermore, we found that we cannot accurately compare transfers, but the type of transfers involves a wide range that allows us to choose the optimal solution for investors.
