Safe, well-tested and rigorously understood
In the event of a fire, Kerto LVL performs more predictably than many non-combustible materials, and has a notional charring rate of 0,7 mm (0.027 inches) per minute. When burned, the surface of Kerto is charred, which protects the product, insulates it, and slows down the burning process. The fire resistance design of Kerto LVL products is conducted according to the EN 1995-1-2 standard and its national annexes. To achieve the fire ratings required for 102 story building, additional fire protection would still be required in the form of sprinklers, and drywall, but many parts of the wood structure could remain exposed. In contrast, the steel structure of the Empire State Building needs to be fully protected by insulation, drywall, stone and other fire resistant materials to provide safe resistance to fire.
Kerto LVL comes only from certified, responsibly managed forests that grow significantly faster than they are used. Four saplings are planted for each tree that we use.
