Insulation industry news from Global Insulation

UK: Knauf Insulation, has achieved the Building Research Establishment’s BES 6001 standard for its responsible sourcing practices. As part of its commitment to sustainability, the insulation producer uses recycled materials across its product range. The business has also developed a sustainable binder for its glass and rock mineral wool products that has no added formaldehyde, acrylics or artificial colours called ECOSE Technology. Knauf Insulation has achieved the standard across its glass and rock mineral wool products manufactured at its production sites in St Helens, Cwmbran and Queensferry.

“As a business that plays a leading role in the built environment, we are continually aiming to minimise risk within our supply chain. BES certification is the latest step towards achieving this and we are pleased to provide an extra level of assurance to our customers,” said John Sinfield, Managing Director at Knauf Insulation.

UK: Knauf Insulation has launched a system to automate the installation of blown glass mineral wool during off-site manufacturing. The new system, called Supafil Frame, is intended to reduce the time required to insulate modular homes. Developed in conjunction with Stewart Milne Timber Systems, it blows un-bonded glass mineral wool into wall panels at the point of manufacture. The insulation producer says that the new system is the first application of its kind in the UK.

Supafil Frame has achieved a Gold rating for indoor air comfort from independent test body Eurofins. It has also been shortlisted in the Product Innovation category of the Structural Timber Awards and Building Awards.

US/Canada: Johns Manville (JM) has launched JM CladStone Water & Fire Block Insulation in the US and Canada. The mineral wool product is for use in cavity wall and rain screen applications. JM says that the product allows for the drainage of water from an exterior wall cavity system.

“We are committed to providing our customers with an array of products to meet the needs of any project, and that’s why we’re introducing JM CladStone Water & Fire Block Insulation, a non-combustible product designed to aid in managing moisture in continuous insulation systems,” said Tommy Knappich, Vice President and General Manager of Building Insulation at JM.

UK: The British Rigid Urethane Foam Manufacturers’ Association (BRUFMA) has said that the materials tested so far by BRE Group, following the Grenfell fire in June 2017, do not meet building regulations and would never be recommended or approved for use by the members of BRUFMA in a real building.

The Department for Communities and Local Government (DCLG) has commissioned six BS 8414 tests using a combination of materials, including the make-up of the outer cladding system. The first aluminium composite material (ACM) cladding test, carried out by BRE combined an assembly of polyisocyanurate (PIR) insulation used in conjunction with an unmodified polyethylene filled ACM cladding panel. Both PIR foam and mineral wool are being tested with each cladding system.

BRUFMA described the situation as ‘worrying’ that a number of buildings have been identified with this combination, indicating a lack of compliance to existing rules and regulations. However, it has advised that all six tests should be completed satisfactorily before any analysis is drawn and remedial action is proposed by the government. It also highlighted that PIR insulation manufactured in the UK and Ireland that is recommended for use in high-rise buildings is tested with the BS 8414 fire test as part of a complete ventilated rainscreen system.

US: Rockwool is planning to build a US$150m mineral wool plant at Ranson in West Virginia. Construction is scheduled to start in October 2017 with production expected to commence in the first quarter of 2020. The new unit will have an area of 43,000m² and employ 150 workers.

“This new production site places us close to major population centres in the north-eastern, mid-Atlantic, and mid-western US. We’re growing along with the market, and we look forward to serving our customers’ needs from this new facility,” said Trent Ogilvie, president of Roxul, Rockwool Group’s subsidiary in North America.

Russia: TechnoNicol has completed the construction of a Euro5.4m briquetting unit at its mineral wool plant in Rostov. The new unit will produce briquettes of waste fibres and smelt from the main production line. These will then be used to produce mineral wool. In addition to improving the plant’s environmental credentials the use of briquettes is also expected to reduce costs.

China: Javier Gimeno, head of Saint-Gobain’s business in Asia-Pacific, has blamed production overcapacity for the company’s decision to stop manufacturing glass wool. He said that overcapacity had forced prices down and lowered margins, according to the Wall Street Journal. He added that the company is targeting profits over 10% and that it wants its business in China to grow faster than the national economy. Subsequently, the group has focused on products such as mortars, plastics and car windows. Gimeno also raised the issue of environmental regulations being stricter for foreign firms in China, although this is changing.

China: Luyang Energy-Saving Materials plans to spend US$11m towards upgrading its mineral wool insulation plant in the Yiyuan Economic Development Zone in Shandong. The upgrade will add 25,000t/yr production capacity to the plant, increasing its total output to 50,000t/yr, according to Reuters. Construction is scheduled to start in July 2017 with completion in June 2018.

Belgium: Knauf Insulation’s chief executive officer (CEO) Jean-Claude Carlin says he is committed to increasing production investment in Europe and North America. The group’s Visé plant in Belgium plans to restart its second line by the end of 2017 as well as adding new capacity to meet increasing demand for blowing wool. An upgrade to a line at St Egidien in Germany is underway following mineral wool production line upgrades at Nova Bana in Slovakia and Skofja Loka in Slovenia in 2014 and 2015 respectively. Another as yet unannounced European production line upgrade is planned for 2018. The group is also restarting the second line at its Inwood plant in West Virginia to support growing residential demand in the North East of the US.

“The first few months of the year proved to be highly promising for the industry and in good times it is vital that we focus on doing an even better job of providing the best possible service and quality for our customers. That is why we are planning on maximising our global footprint through investing in improvements and increasing our production capacity across the globe,” said Carlin. He has conducted a fact-finding mission visiting plants and customers since he took up the post in February 2017.

Australia: Pricewise Insulation says that it is hopeful that a shortage of pink batts mineral wool insulation products will be resolved following the end of a strike at Fletcher Insulation in late May 2017. Workers at the insulation producer started industrial action in mid-February 2017. Pricewise, an insulation distributor noticed falling stock levels of the product during the strike.
