Insulation industry news from Global Insulation

US: Kingspan Insulation has expanded its GreenGuard extruded polystyrene (XPS) insulation board range with additional thickness products and strengths. The range now includes 3 inches and 4 inches in select 25, 40 and 60 psi compressive strength boards, and a new four-sided routed drainage channel board. The new products are intended to extend the GreenGuard line into roofing, cold storage, and various below grade and vertical wall applications markets.

Canada: Icynene has launched two new light density spray foam insulation products: Icynene Classic Ultra and Icynene Classic Ultra Select. A key feature for the new products is the elimination the requirement to paddle mix by hand prior to application with the introduction of an expanding blade mixer. The insulation producer also says that the new products offer significantly better cohesion than existing Icynene open-cell spray foam insulation products. The foams can also be sprayed at drum temperatures from 15℃ for Icynene Classic Ultra and from 20℃ for Icynene Classic Ultra Select

“The introduction of Icynene Classic Ultra and Icynene Classic Ultra Select demonstrates our commitment to delivering customer-valued innovation in the insulation category. Sprayers no longer need to paddle mix the resin material or wait for the liquid to warm up, so they can quickly start spraying these two high quality, high yielding products,” said Mark Sarvary, president of Icynene.

US: Three types of commercial and residential insulation produced by Owens Corning have been certified as made with renewable energy. These products represent the first ever to have met the requirements of SCS Global Services’ certification protocol to validate electricity used to make them is generated entirely from wind.

This certification follows a power purchase agreements Owens Corning signed in 2015 that enabled new wind capacity in Texas and Oklahoma. Both wind farms came online in late 2016 and can generate 1.1MWh/yr of electricity. For every MWh of renewable electricity generated, the company receives one Renewable Energy Credit (REC). It then applies the RECs toward the manufacture of more sustainable products.

“Reducing the embodied carbon in building products has long been a discussion across the building industry,” said Frank O’Brien-Bernini, Owens Corning vice president and chief sustainability officer. “We’re excited to see it come to life through certified products made with renewable energy and reduced embodied carbon.

The three types of insulation available with the wind power certification are EcoTouch Insulation, Thermafiber RainBarrier Continuous Insulation and Unbonded Loosefill Insulation.

US: Israel Chemicals Limited (ICL) is preparing a new flame retardant for use in rigid polyurethane foams. Executives at ICL made the announcement at the Polyurethanes Technical Conference in New Orleans, according to ICIS. VeriQuel R100 is a non-halogenated reactive flame retardant intended to replace tris (chloroisopropyl) phosphate (TCPP) in case of any changes to existing government regulations. The new product will be targeted at building and construction applications.

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: Kingspan has confirmed that a limited amount of its Kooltherm K15 phenolic insulation product was used in Grenfell Tower. In response to a report by Channel 4 News the insulation producer said that a ‘very small quantity’ of the product had been used without its knowledge in a façade refurbishment of the high-rise tower. The building subsequently suffered a fire in June 2017 in which at least 80 people are believed to have died or gone missing.

“Kingspan had no involvement in either the design or the specification of the refurbishment of the Grenfell Tower facade, and neither Kingspan insulated panels nor Kingspan façade systems were used on Grenfell Tower,” said Kingspan in a statement. It added that following the fire it became aware that a limited quantity of Kingspan Kooltherm K15, less than 5% of the estimated total amount of insulation used on the building façade, was sourced by a third party distributer and supplied to contractors involved in the refurbishment. It impressed that, “It appears that Kooltherm K15 has been used without our knowledge, as part of a combination for which it was not designed, and which Kingspan would never recommend.”

The majority of the insulation purchased for use in the building refurbishment was Celotex’s RS5000 polyisocyanurate foam (PIR) insulation board. This product has been stopped for use in rainscreen cladding systems for buildings over 18m tall whilst the investigation into the Grenfell fire continues.

France: Lafarge France and Euromac 2 have signed a national partnership contract to bring to market insulating concrete form products. The deal will see Euromac 2 use Agilia concrete from Lafarge to fill its expanded polystyrene blocks. The two companies will then approve a network of companies to bring the product to the market.

UK: Celotex has stopped supplying its RS5000 polyisocyanurate foam (PIR) insulation board product in rainscreen cladding systems for buildings over 18m tall. The decision is a temporary one whilst an investigation into the Grenfell Tower fire continues. The subsidiary of Saint-Gobain previously confirmed that its product was purchased for use in a refurbishment project at the building. The fire is believed to have killed 79 people.

The insulation producer said that safety testing had been undertaken on its RS5000 product as part of a ‘particular’ rainscreen cladding system. It added that, “…any changes to components of the cladding system or construction methods used need to be considered by the relevant building designer.”

The decision by Celotex follows an announcement by the Metropolitan Police that insulation samples collected from Grenfell Tower combusted quickly in tests. The authorities are examining aluminium composite tiles, the insulation behind it and how these tiles were fixed to the building as well as how they were installed. The aluminium composite tiles have also failed initial safety tests.

Germany: BASF has launched an updated version of its Elastospray LWP spray foam insulation. The product has been changed to respond to European Union (EU) plans to reduce fluorinated gas emission by two-thirds by 2030. Hydrofluorocarbon blowing agents in the product have been replaced with more environmentally friendly alternatives.
