Natural and atificial insulation materials: comparative cost-benefit analysis

Ovim radom se na temelju analize vrši usporedba umjetno proizvedenih materijala za toplinsko izoliranje sa prirodnima. Analizirani umjetni materijali su stiropor, mineralna vuna i poliuretan, a uspoređivani su sa slamom, ovčjom vunom, plutom i papirom. Na temelju analize i usporedbe donesen je zaključak da su prirodni materijali dugotrajniji, neštetni za ljudsko zdravlje, jednostavnija je njihova proizvodnja i ugradnja, koeficijenti toplinske vodljivosti i koeficijenti prolaska topline zadovoljavaju uvijete kao i umjetni, te ono najvažnije u cjelokupnom životnom vijeku ne štete okolišu i nikad ne postaju smeće. No, unatoč svemu tome gotovo da se i ne koriste u RH, jer su nedostupni kao finalni proizvod spreman za ugradnju, nego ih moramo sami proizvesti.In this work is an analysis based on comparison of artificially produced materials for thermal insulation with the natural. The analyzed artificial materials are styrofoam, mineral wool and polyurethane, and they are compared with straw, sheep wool, plum and paper. Based on the analysis and comparison, the conclusion is that natural materials are longer-lasting, harmless to human health, their production and installation is simpler, heat conductivity coefficients and heat transfer coefficients meet the conditions as well as artificial, and the most important is that they in ther overall life-cycle does not harm the environment and They never become garbage. But despite this, they are almost unused in Croatia because they are unavailable as the final product ready for installation, but we have to produce them ourselves
