Metsä Wood Finnjoists (FJI) are manufactured from high quality oriented strand board (OSB3) web, and flanges made from our own Kerto laminated veneer lumber (LVL). Our engineered timber i-beam joists deliver strength and rigidity, virtually eradicating floor movement and its associated problems, resulting in greater floor performance.
Kerto is incredibly strong and dimensionally stable, and it does not distort or shrink. It derives its high strength from the homogeneous bonded structure and is an excellent flange material. The end product is an i-beam which is lightweight yet incredibly strong, resulting in a quick and reliable installation.

Finnjoists have full third party accreditation through the BM Trada Q-Mark and were the first product on the market to gain European Technical Approval (ETA).
All Kerto products are CE marked and certified by VTT Technical Research Centre of Finland, no184/03.
