Analiza vlažnosti lesa na fasadi modelnih objektov po osmih letih izpostavitve v različnih klimatskih pogojih

Perko, Gašper (avtor), Lesar, Boštjan (mentor)

V magistrski nalogi smo analizirali vpliv dolgotrajne izpostavljenosti lesa različnim klimatskim razmeram na šestih lokacijah po Evropi. Preučevali smo vlažnost neobdelanega in termično modificiranega lesa ter učinkovitost različnih zaščitnih premazov, kot so voski in lazure. Meritve so potekale med oktobrom 2015 in majem 2024, pri čemer smo spremljali vlažnost vzorcev fasadnih elementov in okenskih profilov ter vpliv temperaturnih nihanj. Rezultati so pokazali, da imajo podnebni dejavniki, kot so količina padavin, relativna zračna vlažnost in sončno obsevanje, pomemben vpliv na vlažnost lesa. Termično modificiran les je izkazal večjo dimenzijsko stabilnost in nižjo povprečno vlažnost v primerjavi z neobdelanim lesom, pri čemer so bili najbolj učinkoviti zaščitni sistemi tisti, ki so združevali termično modifikacijo in lazure. Sistemi, zaščiteni z voskom, so bili bolj primerni za suha okolja, medtem ko so lazure zagotavljale daljšo obstojnost lesa v vlažnih pogojih. Na okenskih profilih smo ugotovili manjša temperaturna nihanja pri termično modificiranih vzorcih, kar kaže na njihovo izboljšano izolativnost. Ugotovitve prispevajo k boljšemu razumevanju vpliva klimatskih pogojev na lesene fasade in omogočajo optimizacijo izbire materialov ter obdelav za trajnostno gradnjo.

Izvleček

In this master's thesis, we analysed the long-term exposure of wood to different climatic conditions at six locations in Europe. We investigated the moisture content of untreated and thermally modified wood as well as the effectiveness of different protective coatings, such as waxes and glazes. The measurements were carried out between October 2015 and May 2024. The moisture content of façade elements and window profiles, as well as the effects of temperature fluctuations, were monitored. The results indicate that climatic factors, including the amount of precipitation, relative humidity and solar radiation, significantly influence the moisture content of wood. Thermally modified wood showed higher dimensional stability and lower average moisture content compared to untreated wood, with the most effective protection systems being those that combined thermal modification with glazes. Wax-treated systems were found to be more suitable for dry environments, while glazes were more durable in humid conditions. For the window profiles, we observed less temperature fluctuation in thermally modified samples, suggesting improved insulation properties. These results contribute to a better understanding of the effects of climatic conditions on timber façades and support the optimization of material selection and treatment methods for sustainable construction.
