Primerjani sta bili dve rešitvi: lesna vlakna (naravna izolacija) in ekstrudiran polistiren – XPS (umetna izolacija). Eksperiment na objektu je pokazal le majhne razlike v temperaturi in relativni vlažnosti med obema materialoma, medtem ko so WUFI simulacije za štiri različna klimatska območja izkazale bistveno večje razlike. Rezultati kažejo, da se XPS bolje spopada z višjo relativno vlažnostjo in vsebnostjo vode zaradi zaprte celične strukture. Pri lesnih vlaknih je v dveh podnebjih prišlo do nastanka plesni, ker se vlaga v prostoru med izolacijo in opečno steno ni mogla posušiti. Delo poudarja, da je notranja izolacija možna, vendar zahteva natančno higrotermalno analizo in prilagoditev rešitve glede na lokalno klimo, saj naravni materiali v določenih pogojih pomenijo večje tveganje za kondenzacijo in biološko škodo.

Title:	HYGROTHERMAL ANALYSIS OF INTERNAL INSULATION SYSTEMS IN RENOVATION OF CULTURAL PROTECTED BUILDINGS
Abstract:	The master's thesis examines the impact of internal thermal insulation on heritage buildings using experimental measurements and hygrothermal simulations in the WUFI program. Two solutions were compared: wood fiber (natural insulation) and extruded polystyrene — XPS (synthetic insulation). The on-site experiment showed only small differences in temperature and relative humidity between the two materials, whereas the WUFI simulations for four different climate zones revealed significantly larger differences. The results indicate that XPS copes better with higher relative humidity and moisture content due to its closed-cell structure. With the wood-fiber insulation, mold developed in two climates because moisture in the cavity between the insulation and the brick wall could not dry out. The study emphasizes that internal insulation is feasible but requires detailed hygrothermal analysis and adaptation of the solution to the local climate, since natural materials can pose a greater risk of condensation and biological damage under certain conditions.
