Insulation industry news from Global Insulation

UK: Jonathan Roper, a former assistant product manager at Celotex, has described the company as ‘dishonest’ by ‘overengineering’ a cladding fire safety test to achieve a pass for its RS5000 insulation product. After a first test failure in January 2014, a second system passed in May 2014, which the firm used to erroneously market the combustible rigid foam boards as being safe for use on high-rise buildings, the inquiry has heard, according to the Press Association. Covert changes were allegedly made to the set-up of the second test to make the outcome more favourable. Roper added that the motivation for getting the RS5000 product to market was to compete with rival firm Kingspan and its K15 insulation.

Celotex, part of the French multinational Saint-Gobain group, has maintained it promoted RS5000's use on buildings taller than 18m only on a "rainscreen cladding system with the specific components", used when it passed the fire safety test. The inquiry has previously heard Celotex saw Grenfell as a "flagship" for its product and exploited the "smoke of confusion" which surrounded building regulations at the time.

The current stage in the inquiry is examining the production, testing and sale of the materials used in the tower's refurbishment which resulted in the June 2017 fire, killing 72 people. The proceedings continue.

Spain: Saint-Gobain Isover has launched APTA Arena 48, a 48mm thick variant of its sand mineral wool product. It is intended for use with internal partition walls with the 48mm grid system. The product offers thermal resistance of 1.40m2K/W with λ = 34mW/mK.

Ireland: Kingspan has written to the Building Research Establishment (BRE) to withdraw fire test reports on its rigid thermoset phenolic insulation Kooltherm K15. The Irish Times newspaper has reported that, speaking at the inquiry into the Grenfell tower fire in London, a representative of the company admitted that the fire test reports on Kooltherm K15 may not reflect the actual product. This was due to possible compositional changes arising from “process shortcomings” that “fell short of the high standards which Kingspan sets itself." In 2007 it failed a fire test in which it was reportedly tested with a cladding system that also failed subsequent testing with another company’s insulation.

The Grenfell inquiry has asked Kingspan why it had not previously withdrawn the Kooltherm K15 fire test reports with the BRE. A distributor supplied the insulation to contractors for use in the refurbishment of Grenfell in 2012 – 2016.

The majority of the insulation purchased for use in a refurbishment of Grenfell Tower prior to the fire in June 2017 was Celotex’s RS5000 polyisocyanurate foam (PIR) insulation board. However, Kingspan confirmed in July 2017 that a small amount of its Kooltherm K15 product had also been used without its knowledge and that it had no involvement in the design or specification of the refurbishment.

France: Saint-Gobain’s third quarter results for 2020 for its High Performance Solutions division were supported by external thermal insulation products (ETICS). The group said that, “activities serving the construction Industry held up well in the nine-month period, and in the third quarter when sales were virtually stable thanks notably to ETICS.” Despite this sales decreased for the division in both the third quarter and the first nine months of 2020.

The building materials producer’s overall like-for-like sales fell by 7.2% year-on-year to Euro27.9bn in the first nine months of 2020 from Euro32.4bn in the same period in 2019. However, overall sales improved by 3.2% year-on-year to Euro10.1bn in the third quarter of 2020.

UK: A public inquiry has heard that Grenfell Tower cladding subcontractor Harley Facades and staff of Saint-Gobain subsidiary Celotex discussed the use of Celotex’s RS5000 polyisocyanurate foam (PIR) insulation as a “case study” to determine “the U-value achieved by the product.” The insulation product was also sold to the contractor at a 48% discount. Ben Bailey, project manager at Harley Facades, denied that the price had anything to do with the final choice of product for the project. However, other documents showed that Harley Facades staff also enquired about the price of a Kingspan K15 insulation product.

In January 2020 Stephanie Barwise Q.C. told the inquiry that Celotex treated the 67m tall building as a "flagship" project for its RS5000 insulation product.

The Grenfell Tower fire in June 2017 killed 72 people. The inquiry continues.

Netherlands: France-based Saint-Gobain has announced its acquisition of internal finishing and exterior insulation systems specialist Strikolith for an undisclosed price. Strikolith employs 50 people at its Raamsdonksveer, North Brabant plant and generated sales of Euro19.5m in 2019.

Saint-Gobain said, “The complementarity of Strikolith with Saint-Gobain's existing businesses enhances the group's solution offering and in particular allows it to strengthen its offering in External Thermal Insulation Composite Systems (ETICS) and in construction chemicals in the Netherlands, reinforcing Saint-Gobain's leading position in energy-efficient renovation in Europe.”

France: Saint-Gobain’s Point.P construction materials and building products distribution brand has put together a specific range of bio-sourced insulation materials. The materials include wood fibre and hemp-based materials. Point.P says that these products account for 10% of the insulation market. The new range has been developed in response to new expectations expressed by trades professionals and individuals.

Spain: Saint-Gobain Isover has donated Climaver Star mineral wool insulation for use in the construction of the coronavirus field hospital at La Zarzuela University Hospital in Madrid.

On 23 April 2020 Spain’s confirmed coronavirus case count was 213,024, with 22,157 deaths.

UK: Celotex has temporarily suspends operations in the UK due to coronavirus. It said that it continued to support the country’s National Health Service (NHS) and other essential infrastructure and building projects. The subsidiary of Saint-Gobain plans to provisionally reopen in late April 2020, although this will be reviewed.

France: Saint-Gobain’s net profit in 2019 was Euro1.45bn, up by 207% year-on-year from Euro474m in 2018. Its net sales were Euro42.6bn, up by 1.9% from Euro41.8bn in 2018. Saint-Gobain chairman CEO Pierre-André de Chalendar praised the year’s performance in spite of a ‘less supportive market environment in the second half.’ He said, “For 2020, in a more uncertain market environment, Saint-Gobain should continue to benefit from its attractive positioning and from the results of its ‘Transform & Grow’ initiative, and is targeting a further like-for-like increase in operating income with an uncertainty about the impact of the coronavirus.”
