Types of LVL
LVL Ultralam™ timber is made from 9 or more veneer layers with a thickness of about 3 mm, which are laid in the longitudinal direction of the product and glued together parallel to the fibers of adjacent layers. Depending on the direction of the fibers and the grade of veneer layers, the following types of LVL Ultralam™ timber are distinguished:
| Ultralam | Description | Application |
|---|---|---|
| RS / E15 | All veneers are located parallel to grain, G1–G2 grades (primary G1) | Load-bearing structures |
| R / E14 / 2.0psi | All veneers are located parallel to grain, G1–G2 grades (primary G2) | Load-bearing structures |
| X | There are some crossplies, G2–G3 grades structures | Load-bearing structures |
| I / E13, E12 | Both parallel and crossply veneers are possible, G3– G4 grades are possible, G3–G4 grades | Filler structures and parts for doors and furniture manufacturing |
