Laminated veneer lumber (LVL) was laboratory manufactured using veneers from decay and non decay resistant species in order to evaluate changes in the durability as a result of the LVL manufacturing process, and to test if the mixing of decay resistant species and non decay resistant species can improve durability. Laboratory soil block test and field test were conducted. The durability of solid wood was comparable to that of LVL made using the same species. For LVL made using veneer from durable and non-durable wood species, durability was improved when two faces and one core veneers were from decay resistant species.

Natürliche Fäulnisresistenz von Brettschichtholz aus haltbaren und nicht haltbaren Holzarten


Aus fäulnisunbeständigen und -beständigen Holzarten wurde in einem Labor Brettschichtholz hergestellt, um Veränderungen in der Dauerhaftigkeit auf Grund ihres Herstellungsverfahrens zu evaluieren, und um zu prüfen, ob das Mischen von fäulnisunbeständigem mit fäulnisbeständigen Holzarten die Dauerhaftigkeit von LVL verbessern kann. Bodentests wurden im Labor und als Freilandversuche durchgeführt. Bei Verwendung derselben Spezies war die Dauerhaftigkeit von massivem Holz vergleichbar mit derjenigen von LVL. Bei Brettschichtholz, welches aus resistenten und nicht resistenten Arten gefertigt war, wurde die Dauerhaftigkeit verbessert, wenn zwei Aussenschichten und eine Innenschicht aus einer fäulnisbeständigen Holzart war.
