These processes are essential for carbon circulation. However, if wood is used in commercial applications, these processes need to be slowed down as much as possible. When wood is degraded, it has to be replaced. In general, wooden elements are replaced for aesthetic reasons or due to the failure to meet technical requirements. This paper describes the most important mechanisms of wood degradation in outdoor applications. Special emphasis is given to the natural durability of wood and state-of-the-art preservation solutions. In addition, key results on the performance of the wooden on the decking of a study object in Ljubljana are presented. The decking represents a similar exposure to that of bridges, outdoor flooring or roofs, and therefore can be used as a model for the assessment of the performance of wood used outdoorsLes na prostem je izpostavljen delovanju biotskih in abiotskih dejavnikov razkroja. V naravi so ti procesi zaželeni, kadar pa les uporabljamo v komercialne namene, želimo razkroj čim bolj upočasniti. V primeru razvrednotenja lesa pa moramo lesene elemente zamenjati. Lesene izdelke praviloma menjamo zaradi estetskih razlogov ali nedoseganja tehničnih zahtev. V tem prispevku opisujemo najpomembnejše mehanizme in razloge za razgradnjo lesa na prostem, naravno odpornost lesa in sodobne rešitve za zaščito. Na koncu so predstavljeni ključni rezultati o obnašanju lesa na terasi lesenega modelnega objekta na Oddelku za lesarstvo. Terasa ponazarja podobno izpostavitev kot mostovi, pohodne površine oziroma streha, zato je primerna kot odličen prikaz obnašanja lesa na prostemTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaGozdarski inštitut Slovenije
