20.500.12556/RUL-124575 Razvoj lesene kritine Development of wooden roofing Magistrsko delo je nastalo z namenom, da ugotovimo, katera vrsta lesene strešne kritine je v naših klimatskih razmerah najbolj primerna za vsesplošno uporabo oz. kako z uporabo tehnik zaščite, modifikacije in načrtovanjem detajlov zagotoviti najboljšo možno izvedbo strešne kritine. V magistrskem delu so prikazane različne vrste tradicionalnih strešnih kritin, ki so se skozi zgodovino pojavljale po Sloveniji. Podrobno so opisane tehnike in tradicije izdelave skodel v Sloveniji. Med drugim smo omenili tudi nekaj splošnih lastnosti lesa, kot je naravna odpornost in predstavili, kateri dejavniki razkroja vplivajo na les in kako. Seveda odpornost lesa lahko izboljšamo z raznimi metodami, katerih način dela in učinkovitost smo tudi raziskali. Eksperimentalno delo smo začeli z izdelavo, ustrezno pripravo in zaščito vzorcev ter stojal za testiranje. Izbrali smo ključne metode preizkušanja, za katere smo menili, da nam bodo dale največ kakovostnih podatkov. Spremljali smo dinamiko navlaževanja lesene strehe preko monitoringa vlažnosti. Poleg tega smo vzorcem na prostem določali spremembo barve, dovzetnost za razvoj gliv, hrapavost in izmerili stične kote vode s površino. Medtem so v laboratoriju potekali testi navlaževanja, pri katerih smo najprej merili navzem vode ob namakanju, nato še ob izpostavljenosti vzorcev umetnim padavinam. Po analizi rezultatov smo ugotovili, da najbolj uspešno proti vremenskim vplivom kljubuje termično modificiran les v kombinaciji z voskom. As part of this master’s thesis, we wanted to find out what type of wood roof is best for our climate. We wanted to find out how to ensure the best possible implementation of roofing through protection, modification, and detailed design techniques. Different types of traditional roofing that have been used throughout Slovenian history are presented. The techniques and traditions of shingle production in Slovenia are described in detail. Among other things, some general properties of wood, such as its natural resistance, are also mentioned. We have presented factors that cause degradation of wood. The durability of wood can be improved by various techniques. We have studied different methods and their effectiveness. We started the experimental work by preparing and protecting test specimens and test rigs. We selected the main test methods that we thought would give us the most reliable of data. We tested the water behaviour of a wooden roof using moisture monitoring. We also determined the colour changes, fungal susceptibility, roughness, and water contact angle of the samples exposed to weathering. Meanwhile, moisture performance tests were conducted in the laboratory. Water absorption during immersion and artificial precipitation was also determined in the laboratory. The analysis of the results showed that thermally modified wood combined with wax is the most effective combination for the protection of wooden roofs. skodla vremenski vplivi glive odpornost zaščita shingle weather effects fungi resistance protection true false false [A.
