Finnjoist (FJI) is the only fully engineered timber I-Joist to be manufactured in the UK. Our purpose built factory in King's Lynn is the most dynamic production facility available to the market and thanks to recent investments in state of the art machinery is now more efficent, increasing the speed of production and importantly, reduces wastage.

Finnjoists (FJI) are manufactured from high quality OSB3 web, and flanges made from our own Kerto (LVL), delivering less dimensional change over time, virtually eradicating floor movement and its associated problems, resulting in greater floor performance.

We think ahead of the game. Not only do we comply with current legislation, we also strive to continually improve current products and develop new lines through substantial investments in R&D.

Finnjoists have full 3rd party accreditation through the BM Trada Q-Mark and are the first product on the market to gain the European Technical Approval (ETA) and the CE mark.
