LVL, laminated veneer lumber, is an advanced wood product suitable for a wide range of structural applications, from new build to repair. Being one of the strongest wood-based construction materials relative to its weight, LVL provides an ideal solution when strength, dimensional stability and high load-bearing capacity are needed.
The essential benefits of LVL are derived from the choice of raw material used and the manner of production: logs are rotary peeled into 3mm thick veneers and bonded together under heat and pressure. Every sheet of veneer is individually measured in terms of density, moisture content and modulus of elasticity to optimise the product performance. Sheets are then re-glued into a continuous billet on the most advanced production line built to date in Varkaus, Finland.
Typical applications range from posts and beams to roof trusses, wood-frame construction and prefabricated building elements, but LVL is increasingly being used in challenging industrial applications where strength, workability, stability and weight is a concern.
LVL by Stora Enso is available in
- T grade (best suitable for framing elements)
- S grade (best suitable for beams)
- X grade (cross-laminated, best suitable for construction panels and boards).
With the S grade all the veneers run in the same direction enhancing the strength properties of the material that along with its light weight and ease of re-working, make it the ideal choice for the construction industry in a wide range of applications – from framing to beams and from roof components to formwork.
The X grade is constructed by placing some of the veneers cross wise, resulting as a material that has inherent dimensional stability built in. This opens up a host of possibilities for how it can be used – especially in applications where shear strength is a design driver or panels are demanded to fulfil long span floor and roof situations.
