Insulation industry news from Global Insulation

UK: Knauf Insulation and Veolia have officially opened a Euro11m glass-recycling unit at Knauf’s St Helens mineral wool plant. The unit will be able to recycle over 60,000t/yr of used glass that will then be used as a glass cullet source for glass mineral wool production.

"We have been using recycled glass in our manufacturing process for some time already. As well as securing our glass supply, the quality and consistency that we are getting now from the new facility will enable us to increase further the percentage of glass cullet we use in the manufacture of our glass mineral wool insulation solutions, taking us one step further in our sustainability journey,” said John Sinfield, Managing Director at Knauf Insulation Northern Europe.

Veolia's unit sorts and separates glass to produce pure glass cullet. Machinery at the unit includes vibrating screens for size sorting, magnets to extract ferrous materials and eddy current separators for non-ferrous materials. The new facility enables Knauf Insulation to secure its glass supply and maximise the use of recycled materials instead of using virgin minerals. The closeness of the new unit to the St Helens plant is also expected to save around 600,000km of road journeys. Glass mineral wool products from the plant contain up to 80% recycled materials, the vast majority of which now comes from the glass cullet supplied by Veolia. The new recycling unit has also created 18 jobs.

Germany/Poland: Rockwool plans to build new production lines at its stone wool insulation plants at Malkinia in Poland and Neuburg in Germany. The expansions are intended to target demand in new builds and renovation for non-combustible stone wool insulation, particularly in the external wall system and flat roof insulation segments. The upgrade work at Malkinia also includes improved environmental measures.

“Demand for stone wool insulation is expected to grow in key European markets, and expanding existing facilities lets us add capacity relatively quickly. We are also making good progress on multiple initiatives to optimise and upgrade other of our manufacturing facilities to boost output and reinforce our market-leading position,” said Rockwool Group chief executive officer (CEO) Jens Birgersson.

The new production capacity is scheduled to come on line in the second quarter of 2019 in Poland the second quarter of 2020 in Germany. The cost of the investment is approximately Euro175m. The insulation producer is also planning to increase production capacity at other plants through modifications to equipment and workflow to eliminate bottlenecks.

US: Owens Corning has completed its acquisition of Finland’s Paroc Group for Euro900m. Completion followed the US company obtaining all the necessary regulatory clearances to buy the mineral wool producer.

“We’ve had a strategic goal to broaden our product portfolio and diversify our geographic scope to better address our customers’ needs and support their growth. The acquisition of Paroc does both. We now have a leading position in Europe and in the global mineral wool business,” said Julian Francis, president of Owens Corning’s Insulation Business.

China: Luyang Energy-Saving Materials plans to spend US$19m on a new mineral wool production line. The upgrade will increase its production capacity to 80,000t/yr from 50,000t/yr, according to Reuters.

France: Saint-Gobain plans to build a new glass wool production line at its Isover branded plant at Chemillé near Angers. The line is scheduled to start production in mid-2019. It is being built to meet rising demand in the French market for roof insulation products.

In addition, Saint-Gobain is planning to open new production lines at its plants in Azuqueca near Madrid in Spain and Vidalengo near Milan in Italy. These lines will open in spring and autumn 2018 respectively. Altogether Saint-Gobain has invested Euro45m in the upgrades with the majority placed in Chemillé.

Kuwait: Saint-Gobain and Kuwait’s Alghanim Industries have become joint venture partners in insulation producer Kimmco. Kimmco runs a mineral wool plant in Shuaiba-Kuwait, operating under license from Saint-Gobain Isover. It reported sales of around Euro70m in 2016 selling products in Kuwait and the Middle East.

Saint-Gobain and Alghanim Industries already operate joint venture in Turkey (Izocam) and Saudi Arabia (Siimco). Kimmco, like the other common joint-ventures, will be managed jointly by both partners and will be consolidated in Saint-Gobain's accounts.

US: Johns Manville has issued information about an upgrade to the furnace of its Waterville plant in Ohio that took place in the summer of 2017. The work re-started the plant’s furnace and increased its production capacity. The site produces a range of engineered products, such as continuous glass fibres for insulation, composites, building materials and engineered thermoplastic market.

Romania: Saint-Gobain Isover plans to reopen its glass wool production line at its Ploiesti plant in July 2018. The line is expected to restart following a complete furnace rebuild and other upgrades. 50 new jobs will be created in production, logistics and administrative departments.

“The production line allows Isover to adapt its glass wool production capacity to the market demand in the region, given that Romanian market is the largest of the South-East European region. Our decision was generated by the positive trend registered by the construction market in the past year, a trend that is expected to continue over the next years as well,” said Ovidiu Pascutiu, General Manager for Saint-Gobain Rigips and Isover Romania.

Isover has also announced plans to upgrade its stone wool production line at the Ploiesti plant in 2018. The production capacity of the line will be increased by 30,000t/yr in 2019 following the Euro50m upgrade.

Switzerland: Denmark’s Rockwool has purchased all the shares of Flumroc. Previously Rockwool owned a 43.5% share in the Swiss mineral wool producer. Flumroc operates two plants in the country and it sells its products mainly in Switzerland with limited exports to France and Italy. The company will continue to operate under the Flumroc brand.

US: Several of Owens Corning’s Thermafiber mineral wool insulation products and their supporting design and installation services have earned Safety Act Designation from the US Department of Homeland Security. The purpose of the act is to ensure the threat of liability doesn’t prevent companies from developing and commercialising products that could save lives in the event of an act of terrorism. It restricts liability where qualified anti-terrorism technologies, or QATTs, have been used.

“Owens Corning is the first insulation manufacturer to be listed publicly with the Department of Homeland Security as having qualified technology carrying the Safety Act Designation,” said Julian Francis, president, Insulation Business.

The designation covers a variety of Thermafiber products in perimeter fire barrier system, interior wall and floor ceiling systems, construction joint firestopping system and penetration firestopping system applications.
