Panels made of larch bark with 4\u201311 mm and 10\u201330 mm particle size, with ground bark oriented parallel and perpendicular to the panel\u2019s plane at densities varying from 350 to 700 kg\/m3 and bonded with urea-formaldehyde adhesive were analyzed for thermal conductivity, thermal resistivity and specific heat capacity. It was determined that there was a highly significant influence of bulk density on the thermal conductivity of all the panels. With an increase in the particle size, both parallel and perpendicular to the panel\u00b4s plane direction, the thermal conductivity also increased. The decrease of thermal diffusivity was a consequence of the increasing particle size, mostly in the parallel orientation of the bark particles due to the different pore structures. The specific heat capacity is not statistically significantly dependent on the density, particle size, glue amount and particle orientation.<\/jats:p>","DOI":"10.3390\/polym13142287","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T21:56:37Z","timestamp":1626126997000},"page":"2287","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Thermophysical Properties of Larch Bark Composite Panels"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2385-5760","authenticated-orcid":false,"given":"Lubos","family":"Kristak","sequence":"first","affiliation":[{"name":"Faculty of Wood Sciences and Technology, Technical University in Zvolen, 96001 Zvolen, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2937-7867","authenticated-orcid":false,"given":"Ivan","family":"Ruziak","sequence":"additional","affiliation":[{"name":"Faculty of Wood Sciences and Technology, Technical University in Zvolen, 96001 Zvolen, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2979-5893","authenticated-orcid":false,"given":"Eugenia Mariana","family":"Tudor","sequence":"additional","affiliation":[{"name":"Forest Products Technology and Timber Construction Department, Salzburg University of Applied Sciences Markt 136a, 5431 Kuchl, Austria"},{"name":"Faculty of Furniture Design and Wood Engineering, Transilvania University of Brasov, B-dul.
