Following Natures lead STEICO construction products combine high load bearing capacity with the highest efficiency.

Nature shows us the way by producing slender constructions with maximum stability. The functional principles are simple: Reduction. Where no material is required then no material is wasted. The Result: improved material properties with low weight and low primary energy consumption whilst providing the highest energy efficiency. The STEICO building system follows these principles.

STEICOjoists are especially lightweight, energy efficient elements that uses a slender web material from natural fibreboard, or OSB, to connect the two flanges. The flanges are made of laminated veneer lumber STEICO LVL R. This guarantees consistently high quality and defined strengths.

STEICO LVL consists of several layers of bonded softwood veneers. This structure gives STEICO LVL its high strength. Laminated veneer lumber is one of the most resilient timber construction materials available.

The STEICO Building System with STEICOjoist, STEICOwall and STEICO LVL are certified as Passive House components by the Passive House Institute.

/ wall | STEICO LVL Laminated Veneer Lumber - -I-Joist Building System for floor, roofs & walls STEICO LVL is made of multiple 3 mm layers of graded laminated veneers. This disperses knots and irregular growth, producing a practically homogenous cross-section. This construction means that STEICO LVL is highly rigid and dimensionally stable.
