2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS 2.5.9 Other applications LVL-P is an essential component of the common engineered wood product, the I-joist. As LVL-P has a high and consistent E-modulus and is available in long lengths, it is well suited as flange stock material for the production process of I-joists for floor structures. I-joists are usually sold as a complete system containing the specific design and detailing for individual building projects and are CE marked according to the supplier’s ETA assessment. Typical I-joist heights are 200-400 mm and flange widths 38-96 mm. In low-energy housing I-joists and studs are used also in exterior wall and roof structures. Figure 2.94.

They are proof loaded to ensure reliable and safe working on the construction site. LVL-P planks have a good working life and are light to carry and easy to install. One advantage of LVL scaffold planks is their high fire safety, as there is no risk of sparks if a metal member hits a plank, making them ideal for applications such as oil refineries and shipyards.
