CLT production has been increasing rapidly in recent years. CLTis suitable for wall, floor, ceiling and roof elements in the construction of houses, multi-family apartment buildings, industrial and storage halls and other buildings and bridges. Manufacturers demonstrate compliance with the essential requirements of the European Construction Products Regulation (CPR) on the basis of an initial type testing and the findings of a factory production control examination. In 2015, a harmonized European standard for CLT was adopted,which defines the requirements for built-in materials, the production and demonstration of constancy of performance,and the CE marking. The article presents the production technology and basic characteristics of CLT and the content of standard EN 16351Križno lamelirani les (KLL) je sodoben gradbeni material, ki se uporablja za nosilne gradbene namene v stanovanjskih in nestanovanjskih objektih. Proizvodnja KLL v zadnjih letih zelo hitro narašča. KLL je primeren za stenske,talne, stropne in strešne elemente pri gradnji hiš, večstanovanjskih stavb, industrijskih in skladiščnih hal ter drugih zgradb in mostov. Izpolnjevanje bistvenih zahtev evropske uredbe o gradbenih proizvodih (CPR) proizvajalci dokazujejo na podlagi začetnega testiranja tipa proizvoda in ugotovitev kontrole proizvodnje v obratu. Leta 2015 je bil sprejet harmoniziran evropski standard za KLL, v katerem so definirane zahteve za vgradne materiale, proizvodnjo in dokazovanje nespremenljivosti lastnosti ter označevanje z oznako CE. V članku so predstavljene tehnologija izdelave in osnovne značilnosti KLL ter vsebina standarda EN 16351TEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza lesarjev Slovenije
