The improvements include a complete rebuild of the furnace at the heart of the plant. The work has been completed as part of a £200m investment programme to increase the company’s manufacturing capacity and capability, which includes the construction of new plants in France and Malaysia. “We’ve seen increased demand over the last 18 months as architects, contractors, developers and regulators have recognised the benefits of high-performance, non-combustible mineral wool insulation” said John Sinfield, Managing Director, Knauf Insulation. “All indications suggest this trend will continue, which is one of the reasons we’ve invested in this comprehensive upgrade of our Cwmbran facility.” £7m Plant Upgrade The programme of work at the plant was scheduled to take six weeks, but was completed three days early. It included a complete rebuild of the furnace, and plant-wide refurbishments and modifications. The programme also includes energy efficiency improvements with new compressors, drives and motors installed which will reduce the plant’s CO2 emissions by just under 7,000 tonnes per year. During the works, the plant’s 207 employees volunteered their time with local charities under Knauf Insulation’s ‘Community Matters’ programme. In total, 576 hours were given over to supporting four local causes, including two hospices, a resource centre for people with learning disabilities, and an animal rescue facility. Knauf Insulation’s Cwmbran plant manufactures Glass Mineral Wool for use in a wide variety of applications. Products made at the site include the Supafil® range of blowing wools for cavity insulation, and the Earthwool® range of high-performance rolls and slabs for use in traditional and off-site construction. Knauf Insulation’s new Rock Mineral Wool plant in France is expected to come online in 2019, with the new Glass Mineral Wool plant in Malaysia following in 2020. >> Read more about Knauf Insulation in the news Previous article Record Number of First Year Roofing Apprentices for Leeds College of BuildingNext article UK Construction Output Increases as Outlook Deteriorates Share article You may also like View all News Industry News +2 20 March 2026 RA Issues Revised Safety Guidance on Rooflight Covers Awards and Events +3 20 March 2026 The Great British Slate Off Returns for 2026 Green Roofs +3 20 March 2026 Swansea Joins Global Network of Biophilic Cities Featured Solutions +3 19 March 2026 Flush Fitting Rooflights by Clement Sign Up to Roofing Today Stay up to date with all of the latest news from Roofing Today by signing up to our weekly Bulletins… Sign Up Today Get in Touch Check out the latest issue 123 March-April 2026 View Now Past Issues Get in Touch
