V diplomskem delu je obravnavana toplotna izolacija zidov, ki po površini predstavljajo največji del konstrukcije in ovoja stavbe. Obravnavani so štirje različni materiali za toplotno izolacijo ovoja zgradbe. Predstavljene so njihove temeljne lastnosti in kakšen je njihov vpliv na okolje. Izračunane so potrebne debeline vsakega materiala posebej za točno določeno toplotno prehodnost ter cene, ki so povzete po veljavnih cenikih posameznih materialov. Iz analize cen je izbran najcenejši material. Rezultati kažejo, da je cenovno najugodnejši material steklena volna in ne ekspandirani polistiren, ki je sicer najpogosteje uporabljen material za toplotno izolacijo. Ugotovili smo, da so razlike v ceni med temi štirimi materiali precejšnje, saj je najugodnejši material trikrat cenejši od najdražjega. In this thesis we deal with the thermal insulation of walls, which represent the largest part of the construction and building envelope on the surface. Four different materials for the thermal insulation of the building envelope are considered. Their basic characteristics and their effect on the environment are presented in this thesis. The thicknesses of each material is calculated for the specific heat transfer and the prices, which are summarized according to the valid price lists of each individual materials. The cheapest material is selected from the price analysis. The results show that the cheapest material is glass wool and not expanded polystyrene, which is the most commonly used thermal insulation material. We found that the price differences between these four materials are considerable, since the most favorable material is three times cheaper than the most expensive ones. |
