Finnjoist I-Beam

I-Beam Joists delivering strength and stability for your engineered wood flooring

​​​​​​​​​​​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® LVL 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.

Fire test information

In conjunction with an accredited test laboratory, we have undertaken a fire safety test to determine the fire resistance according to BS EN 1365-2:2014 of a wooden floor construction with Finnjoists, OSB flooring, insulation, Resilient Bar and two layers of plasterboard ceiling.

It achieved 60 minutes' fire resistance, but the test was stopped at 75 minutes.
