Knauf Insulation Completes £40m+ Upgrade at St Helens Plant

KNAUF INSULATION has completed a major upgrade of its glass mineral wool manufacturing plant in St Helens.

The investment increases roll, slab and blowing wool capacity by up to 25,000 tonnes, adding new product capability and further reducing the embodied carbon of products made at the site, the largest glass mineral wool plant in the UK.

The upgraded plant was officially reopened yesterday by Knauf Group General Partner Alexander Knauf and Liverpool City Region Mayor Steve Rotheram. Joining them were representatives from St Helens Borough Council and senior personnel from the Knauf Insulation Group.

“Glass mineral wool insulation is central to meeting the UK’s housebuilding and energy efficiency needs,” said Neil Hargreaves, Managing Director, Knauf Insulation Northern Europe.

“This upgrade means we can deliver increased volumes and enhanced products for our customers to meet rising demand for warmer, safer and sustainable homes with lower energy bills.”

Upgrade at St Helens Plant

The Knauf Insulation plant now features UK-first forming technology. It will enable Knauf Insulation to create the next generation of low thermal conductivity, non-combustible glass mineral wool products and add thicker options to its existing ranges.

The extensive programme of work involved over 1,100 contractors over a 6-month period. It included installation of a larger plant furnace which is used to melt the main raw material, of glass cullet, collected via local household recycling.

Touring the plant, Steve Rotheram said, “I’ve really enjoyed the visit and the tour of the new facilities. What it shows is a real demonstration of confidence, not only in the product or even in the process, but in the people of this area. St Helens is famous for glass. With a facility like this we’re going to be right at the forefront of investment and the economic growth that stems from it. It’s great for the City Region.”

Knauf Group General Partner Alexander Knauf commented “Our people make things happen. What I saw here today makes me feel extremely proud. It’s incredible what the team has achieved over the last months. To make such a project happen has taken a true team effort from everyone. They have done an amazing job to help make tomorrow a home for all of us.”
