Kerto® LVL is structural laminated veneer lumber used in all types of construction projects, from new buildings to renovation and repair. Kerto LVL combines excellent technical performance with ease of use. Its essential qualities include strength and rigidity, dimensional stability and light weight.
Kerto LVL is produced from 3 mm thick rotary-peeled strength graded softwood veneers. The veneers are bonded with weather- and boil-resistant phenol formaldehyde adhesive to form a continuous billet. The billet is cut to length and sawn into LVL beams, planks or panels according to customer´s requirements.
Further processing
The Kerto acoustic fire door blanks are manufactured from premium Nordic Spruce. The Kerto LVL Q-panel used for the door blanks is a cross-bonded laminated veneer lumber (LVL) produced from rotary-peeled 3 mm graded softwood veneers, which are then glued together using EN 636-3 glue (for use in exterior conditions). Individual veneer joints are scarfed and staggered. This structure improves the lateral bending strength and stiffness of the panel, thus increasing the shear strength. With cross-bonded veneers, there is an essential reduction in moisture dependent variations across the width of the panel. The result is an engineered wood product which delivers strength and dimensional stability that does not warp or twist, ideally suited to door blank applications.
