Insulation industry news from Global Insulation

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.

Czech Republic: Rockwool is planning to use its Bohumin plant’s full production capacity to make mineral wool in 2017. In 2016 the unit produced a record 4Mm³ of the product and so far it has produced 80% of this in the first nine months of 2017, according to the CIA news agency. The increased production levels follow an upgrade at the site in 2015. Insulation products from Bohumin are sold locally, in Slovakia and elsewhere in Europe.

Poland: Finland’s Paroc is spending around Euro60m on an expansion project at its Trzemeszno mineral wool plant. A new 70,000t/yr stone wool production line will be built at the site. The upgrade is expected to be completed in 2019.

"This is an important step for Paroc to continue the profitable growth. Demand for insulation has been increasing, especially in the Central and Eastern Europe. With increased production capacity we are able to grow together with our customers and improve our competitiveness and efficiency," said Kari Lehtinen, chief executive officer (CEO) of Paroc.

Sweden: Denmark’s Rockwool has purchased 180,000m² of land in the eastern Swedish municipality of Eskilstuna. The acquisition is intended for future growth and to allow the mineral wool producer to meet any potential rise in demand for its products. At present the company supplies the Swedish market with products manufactured at plants in Denmark and Norway.

New Zealand: TechnoNicol’s Techno mineral wool plant in Ryazan has sent a test batch of products to New Zealand. Following feedback the insulation producer plans to arrange a regular export of materials to the region.

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.
