Finnframe Flooring System

​​​​​​​​​​​​​​The Finnframe Floor System does the job of specifying for you. It converts your own floor plans into a 3D image of the supporting structure, together with a complete bill of materials and detailed site plans. Those plans go with our Finnjoist i-beams and other engineered wood products to provide a comprehensive drawing-board to building site flooring system.

Fully engineered high performance flooring solution 

The Finnframe Flooring Product range includes:

  • Finnjoist (FJI) - Manufactured at our factory in King's Lynn, Finnjoists are strong, stable and lightweight. Finnjoists were the first I-Joists on the market  to have European Technical Approval (ETA) and CE marking.
  • Kerto® LVL - A strong, lightweight, rigid and dimensionally stable timber product made from 3mm rotary-peeled spruce veneers.
  • Kerto® LVL S-beam - Manufactured from veneers laid in the same direction, ideal for beams and long spans.

  • Kerto® LVL Q-panel - Engineered in the same way as S-beam but with some cross-laid veneers, giving dimensional stability and excellent load bearing performance.

Finnframe software package

Advanced design package that saves time, eliminates wastage, and offers certainty by turning your floor plans into a detailed specification that complies with current British and European standards.

​​Finnframe installation app

Accessible from any smart phone or tablet (Windows, Android or iOS based), our newly released app provides static drawings of design details and animated sequences demonstrating the correct installation procedure.​

The Finnframe Installation app works in conjunction with the Finnframe specification provided to our housebuilder customers. Detailed design drawings will identify specific details by code - eg M7a - and the contractor will simply cross reference the code with the app on their phone to watch the brief annotated video.
