Spremljanje vlažnosti lesa v lopi, izdelani iz termično modificiranega lesa : diplomski projekt = Monitoring of wood moisture content in hut made of thermaly modified wood : B. Sc. thesisJarc, TadejKot vsaka gradnja ima tudi gradnja z lesom svoje zakonitosti in omejitve. Ker želimo, da je življenjska doba čim daljša, moramo poznati zakonitosti lesa kot gradbenega materiala. Les je obnovljiv vir ... in ekološko malo obremenjujoč za okolje. Kot naravni material je podvržen razkroju. Predvsem ga okužijo razne vrste gliv in plesni. Za vse je značilno, da dobro uspevajo le ob določeni lesni vlažnosti (od 30 % do 60 %) in temperaturi (med 23 °C in 30 °C). Les ima že svojo naravno odpornost, vendar pa iz ekonomskih razlogov želimo to lastnost še izboljšati. Najbolj poznan postopek za izboljšanje naravne odpornosti lesa je impregnacija z biocidi. V sodobnem času pa se pojavlja postopek termične modifikacije, ki obeta zelo dobre rezultate. Če želimo zadržati lesno vlažnost pod kritično mejo, jo moramo meriti z različnimi merilniki. Najbolj poznani so uporovni merilniki. Na objektih Partizanske bolnice Franja in Mozirskega gaja je bil kot merilnik uporabljen Gigamodul z zapisovalnikom Thermofox proizvajalca Scanntronik. Oba objekta sta izdelana iz smrekovine. Objekt Partizanska bolnica Franja stoji v ozki grapi, v neposredni bližini tekoče vode in je v celoti izdelan iz impregniranega lesa, medtem ko je objekt v Mozirskem gaju izdelan iz termično modificiranega lesa, le dva manjša elementa sta izdelana iz impregniranega lesa, kar nam je služilo kot neposredna primerjava med impregniranim in termično modificiranim lesom. Ugotovili smo, da ima termično modificiran les nižjo vlažnost od impregniranega lesa in je tako zagotovljena daljša življenjska dobaType of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
