Cross laminated timber is an innovative plate-shaped product presenting a laminated structure and excellent physicomechanical properties. Due to its high stiffness and in-plane and out-of-plane bearing capacity, it is most often used in form of wall or floor panels. Favourable environmental, aesthetic and energy properties further enhance its qualities. The paper is a summary of CLT research conducted so far, with an emphasis on the need to harmonise existing regulations and include this product in the European standard for timber structures Eurocode 5.

Križno lamelirano drvo (eng. Cross Laminated Timber – CLT) inovativni je pločasti proizvod slojevite strukture i izvrsnih fizikalno-mehaničkih svojstava. Zbog velike krutosti i nosivosti u ravnini i okomito na ravninu elementa najčešće se primjenjuje u obliku zidnih ili stropnih panela. Povoljna ekološka, estetska i energetska svojstva dodatno ga pospješuju. Rad prikazuje sumarni pregled dosad provedenih istraživanja CLT-a, s naglaskom na potrebnu harmonizaciju postojećih propisa i njegovo uključivanje u europsku normu za drvene konstrukcije Eurokod 5.
