Comperative analysis of insulation materials

Cilj rada je bio usporediti umjetne i prirodne toplinsko-izolacijske materijale. Za umjetne toplinsko-izolacijske materijale odabrani su stiropor i kamena vuna, a za prirodne materijale slama i ovčja vuna. Usporedbom materijala se vidi koji su materijali najčešće korišteni, njihova svojstva, prednosti, mane i cijena. Zaključak na temelju usporedbe jest da su prirodni materijali jednake efikasnosti kao i umjetni materijali. Na temelju usporedbe jednostavnija je proizvodnja i ugradnja prirodnih materijala, koeficijenti toplinske vodljivosti i koeficijenti prolaska topline zadovoljavaju uvjete kao i umjetni, te u cjelokupnom životnom vijeku ne štete okolišu. Unatoč navedenom gotovo da se i ne koriste u Hrvatskoj, zbog toga jer su ti materijali nedostupni kao finalni proizvod spreman za ugradnju, već ih korisnici trebaju samostalno proizvesti.The goal of this paper was to compare artificial and natural thermal insulation materials. For artificial thermal insulation materials styropor and rock wool were chosen, as for natural materials straw and sheep wool were chosen. In comparison of materials it can be seen which materials are commonly used, what are their properties, as well as their cons and price. The conclusion based on this comparison is that natural materials are equally efficient as are artificial materials. Based on comparison roduction and installation of natural materials is simpler, coefficient of thermal conductivity and of thermal transmittance satisfy demands as good as artificial materials, and in their lifespan don't harm the environment. In spite of mentioned pros they are hardly used in Croatia due to the fact that these materials are unavailable as final product ready for installation so users have to produce it on its own
