Possibilities of Use Recycled Materials in Construction Details

This paper aims to explain the use of secondary materials in design details. Primarily, attention is paid to flat roofs, for which there is currently a wide range of technologies needed for user-friendly operation of a building. Recycled materials are still often looked down on and, therefore, it is important to show that even these elements may work very well in constructions. They must meet strict criteria for static and thermal properties. Furthermore, they must comply with fire and weather resistance requirements. They also have acoustic, secondary and aesthetic function. The roof structure is one of the basic segments that characterize the final properties of the building. Any malfunctions will lead to increased economic costs and degradation of users’ environment
