Aim of subject is acquainted students with the design of rooof constructions and roofing systems of building for specified climatic conditions and functional requirements. Received knowledge enable students design of roof constructions and roofing envelope and application of suitable selection of materials, building constructions and design of envelope composition for determined boundary conditions external and internal environment. Received knowledge further enable to evaluate and to analyse thermal and moisture problems in roof envelope and in the composition of constructions of flat and slope roofs.
