20.500.12556/RUL-187640 Možnost uporabe recikliranega materiala za toplotno izolacijo stavb diplomsko delo The potential use of recycled materials for thermal insulation of buildings Diplomsko delo obravnava možnost uporabe recikliranih materialov za toplotno izolacijo stavb s poudarkom na njihovi toplotni učinkovitosti in vplivu na okolje. V prvem delu smo predstavili najpogosteje uporabljene konvencionalne toplotnoizolacijske materiale ter možnost ponovne uporabe in recikliranja odpadne kamene in steklene volne ter ekspandiranega in ekstrudiranega polistirena. Pregledali smo tudi trenutno ponudbo proizvajalcev in vključevanje recikliranih surovin v proizvodnjo toplotne izolacije. V nadaljevanju smo izbrane izolacijske materiale iz obnovljivih ali recikliranih surovin primerjali s konvencionalnimi izolacijami glede na njihove fizikalne, toplotne in okolijske lastnosti. Primerjalne izračune smo izvedli na konstrukcijskem sklopu zunanje zidane stene s ciljno toplotno prehodnostjo 0,18 W/(m2K) in poševne strehe z leseno nosilno konstrukcijo s toplotno prehodnostjo 0,15 W/(m2K). Za posamezne izolacijske materiale smo določili potrebno teoretično debelino, izbrali dejansko razpoložljivo debelino proizvoda ter ponovno izračunali doseženo toplotno prehodnost. Na podlagi podatkov iz okoljskih deklaracij proizvodov smo primerjali tudi potencial globalnega segrevanja zaradi fosilnih virov (GWP-fossil), potencial globalnega segrevanja zaradi biogenih virov (GWP-biogenic) in porabo neobnovljive primarne energije (PENRT). Rezultati so pokazali, da lahko obravnavani izolacijski materiali iz obnovljivih in recikliranih surovin ob ustrezni debelini dosegajo zahtevano toplotno učinkovitost, med posameznimi rešitvami pa se pojavljajo izrazite razlike v njihovem okolijskem vplivu. The thesis examines the potential use of recycled and alternative materials for the thermal insulation of buildings, with an emphasis on their thermal performance and environmental impact. The first part presents commonly used conventional thermal insulation materials and discusses the possibilities for reusing and recycling waste stone wool, glass wool, expanded polystyrene, and extruded polystyrene. The current market supply and the incorporation of recycled raw materials into insulation production were also reviewed. Selected alternative materials were then compared with conventional insulation materials in terms of their physical, thermal and environmental properties. Comparative calculations were performed for an external masonry wall with a target thermal transmittance of 0.18 W/(m²K) and a timber roof structure with a target value of 0.15 W/(m²K). For each insulation material, the required theoretical thickness was calculated, an actually available product thickness was selected, and the resulting thermal transmittance was recalculated. Based on data from Environmental Product Declarations (EPDs), global warming potential from fossil sources (GWP-fossil), global warming potential from biogenic sources (GWP-biogenic), and non-renewable primary energy use (PENRT) were also compared. The results showed that the analysed alternative materials can achieve the required thermal performance when appropriate thicknesses are used, while considerable differences exist among individual solutions in terms of their environmental impact. diplomske naloge gradbeništvo toplotna izolacija recikliranje volna polistiren odpadki toplota ponovna uporaba graduation thesis civil engineering thermal insulation recycling wool polystyrene waste heat reuse true false false [M.
