1. LVL AS A CONSTRUCTIONMATERIAL

1.1.2 LVL-C with cross-bonded veneers

for robust structural panels

LVL-C panel is a cross-bonded panel product with approxi-

mately 20% of the veneers glued in a crosswise direction. This

enhances the transverse strength and stiffness and the con-

nection ductility of the panel. It is dimensionally stable, as the

cross veneers prevent shrinkage and swelling in the event of

moisture changes in the panel width direction. LVL-C panels

or beams can be used as both horizontal and vertical bearers

in numerous construction applications. It is designed for use as

a large-dimension load-bearing panel, as well as for structural

bracing and stabilizing. LVL-C panel is an ideal component for

floor, wall and roof elements, roof and wall panels, and pre-fab-

ricated houses. The panels can be cut to tailored sizes and spe-

cial shapes for modern timber structures

Panel applications

Features and benefits

• Large panel product for roof, floor and wall constructions

• Roof overhangs

• Pre-fabricated roof, floor and wall elements and modules

• Stresses-skin panel elements

• Door panels

• Strong and rigid: long spans with minimal deflection

• Large dimensions: applications in a wide variety of building

types

• Installation efficiency: large panel for floors, roofs and walls

covers vast areas much faster than normal size wood-based

panels reducing the amount of lifting required on the

construction site.

• High and thin beams: energy efficient constructions

• Straight and dimensionally stable; does not warp or twist:

improves construction quality

• Dry from factory: minimal shrinkage in constructions

• Customized product dimensions and shapes with minimum

waste: applications in a wide variety of building types; savings

in material costs and time on construction site

• Excellent strength-to-weight ratio: light structures

• Great workability: easy to install, staple, nail, drill and cut

without special tools

• Ductility of connections: improved safety

• Strong and rigid in edgewise compression perpendicular

to grain direction: better building quality with minimal

deformation, suitable for narrow supports

• Not sensitive to cracking under tension perpendicular to grain

stressed structures: safe connections

• Bracing of different size buildings, regardless of frame

material: applications in a wide variety of building types; large

window openings possible.

Other applications

• Rim boards

• High rafter beams

• High lintels and header beams

• Frames and truss members

• Reinforcement of old structures

• Curved components, free-form beams and panels

(CNC machining)

• Concrete formwork
