Kerto® LVL

Kerto LVL laminated veneer lumber products are used in all types of construction projects, from new buildings to renovation and repair. Kerto LVL is made from 3 mm thick, rotary-peeled and strength-graded softwood veneers. The veneers are bonded with weather- and boil-resistant phenol formaldehyde adhesive and manufactured as a continuous billet. The bonding process meets the requirements of the EN 14374 standard. The face veneer scarf joints on the front side of the product are glued using colourless adhesive. During hot pressing, the adhesive cures into a thermoset plastic and is therefore inert and non-hazardous to humans and animals. The billet is cut to length and sawn into Kerto LVL beams, planks, or panels according to customer requirements.

In Kerto LVL S-beam and Kerto LVL T-stud, all veneers are oriented in the same direction. In Kerto LVL Q-panel, Kerto LVL Qp-beam, Kerto LVL L-panel, and Kerto LVL D-panel, part of the veneers are oriented crosswise to enhance transverse strength and stiffness. Kerto LVL products are CE-marked in accordance with the EN 14374 standard.

Kerto LVL is suitable for both load-bearing and non-load-bearing structures, such as beams, headers, studs, columns, and panels for roof, wall, and floor elements. It can be used in fully wooden structures or in combination with other building materials. Metsä Wood’s partners develop elements and modules using Kerto LVL products and element systems. The service life of Kerto LVL is considered to be equivalent to the lifetime of the building, provided the product is installed according to instructions. For numerical assessment purposes, a service life of 100 years may be used
