The Timber Systems Division was launched 25 years ago as the UK’s first I-joist production line and has since grown to become the UK’s largest manufacturer of certified I-joists, branded as JJI-Joists. Today JJI-Joists have a 40% share of the UK’s I-joist market and are used by every major UK housebuilder in addition to supplying customers across Europe, Australia and New Zealand.

“This is a major milestone for the Timber Systems Division and the extensive programmes of capital expenditure and innovation,” said Tom Bruce-Jones, chairman of James Jones & Sons Ltd. “Since its inception we have produced well in excess of 100 million lineal metres of JJI-Joists and stored over 455 thousand tonnes of embedded carbon in approximately 1 million new homes.

“In recent years developments have included £8.5m investment into the commissioning of a new world leading I-joist production line, a stock yard extension and the addition of JJI-Wall stud to our EWP portfolio to help housebuilders meet new Part L building regulation requirements.”

“We are delighted to celebrate our anniversary and it is testament to the hard work and dedication of our team over the past 25 years,” added Angus Macfarlane, general manager of Timber Systems Division. “Many employees that started with us in the beginning are still with us today and will have witnessed a great deal of change and progression in that time. To mark the occasion, all employees signed a JJI-Joist that was produced on the day of the anniversary and it will be displayed inside the building.”
