Insulation supplier Knauf Insulation is planning to invest circa€200 million in a new state-of-the-art rock mineral wool factory for the UK market. The large-scale facility will use cutting-edge, low-carbon electric melting technology, and have an annual capacity in excess of 100,000 tonnes,

Through this investment, Knauf Insulation will achieve two key goals: decarbonising and significantly increasing its UK supply of rock mineral wool products, in addition to its existing Queensferry plant. The new factory will address the market’s growing need for insulation solutions with ultra-low embodied carbon, and play a key role in helping the UK achieve its net zero targets.
Knauf Insulation’s managing director for Northern Europe, Neil Hargreaves, said: “Following the €50 million+ investment across our two UK glass mineral wool plants in 2023/4, this represents another exciting development for the business and our valued customers, as well as a further sign of confidence from Knauf Group in the future growth of the UK and Northern European mineral wool markets. The investment represents a step change in the capacity, capability, and sustainability of our UK rock mineral wool solutions, whilst significantly contributing towards Knauf Group’s ambitious sustainability goals.”
It is anticipated the additional capacity will become available in 2026. Knauf Insulation is engaged with authorities to select the most competitive location for the facility, in order to maximise its future success.
