Abstract

Ena izmed ključnih lastnosti pri gradnji stavb je toplotna izolativnost stavb. V sodobnem gradbeništvu predstavlja velik izziv zmanjšanje porabe energije, ki nastaja pri izdelavi umetnih izolacijskih materialov. Na vzorcih naravne toplotne izolacije iz lesenih vlaken, iz konoplje, plute ter ovčje volne smo z metodami določitve tlačne trdnosti pri 10% deformaciji, določitvi kontaktnega kota ter mikroskopiranjem ugotavljali, kako staranje vpliva na toplotno izolacijo. Prišli smo do ugotovitev, da so se tlačne trdnosti vsem izolacijskim materialom po staranju zmanjšale, ter da se je zmanjšal tudi kontaktni kot naravnih toplotnih izolacij. Mikroskopiranje je pokazalo, da je po staranju prišlo do razplastitve plasti naravnih toplotnih izolacij.

Secondary title:	The effect of accelerated aging on the properties of natural insulating materials made of hemp, cork, wood and sheep`s wool
Secondary abstract:	One of the key properties in the construction of buildings is the thermal insulation of buildings. In the modern civil engineering industry, a major challenge is the reduction of energy consumption, which is generated during the production of artificial insulation materials. On samples of natural thermal insulation made of wood fibres, hemp, cork and sheep's wool, we used the methods of determining the compressive strength at 10% deformation, determining the contact angle and using microscopy to determine how aging affects thermal insulation. We came to the conclusion that the compressive strengths of all insulating materials decreased after aging, and that the contact angle of natural thermal insulations also decreased. Microscopy showed that, after aging, the layers of natural thermal insulation were delaminated.
