Home / glossary / LVL I-joists

The functional principle for I-joists is as simple as it is impressive: reduction. Where no material is needed, no material is wasted. The result: improved properties with low weight, low primary energy consumption and maximum energy efficiency. The flange material is made of highly durable LVL laminated veneer lumber, one of the most resilient wood-based materials available. The web is made of natural fiber boards, a wood-based material characterized by particularly high shear strength.
