Insulation industry news from Global Insulation

Romania: France-based Saint-Gobain has acquired Duraziv, a producer of adhesives and other construction chemicals. The group said that the purchase would allow it to expand its range of interior and exterior finishing solutions. It also hopes the move will drive an improvement in the energy efficiency of buildings in Romania thanks to external thermal insulation solutions (ETICS) based on locally-produced stone wool and mortars. This latest addition follows the recent acquisition of Russia-based Adhesive Scientific and Production Company, a producer of polyurethane (PUR) and epoxy products.

US: France-based Saint-Gobain has awarded a contract to MTI Instruments to supply its Digital Accumeasure non-contact measuring technology. The group will use the product to measure closed-cell foam density in its production process. It said that the partnership aims to increase the number of process improvement products which reach plant implementation.

Saint-Gobain Competency Research Laboratories smart manufacturing team leader Mickael Boinet said "We chose MTI Instruments' Digital Accumeasure product for many reasons. The non-contact technology was just one of the pluses.” He added "We investigated various impedance measurement companies in Europe, but ultimately determined that the amplifier made by MTI Instruments was superior."

Spain: Saint-Gobain Isover has launched the Geowall range of stone wool insulation. The range consists of Geowall 34, Geowall 35 and Geowall 37. The company says that the range replaces its Acustilaine products. It is non-hydrophilic and uncoated for excellent thermal and acoustic performance. It called Geowall the ‘optimal choice’ for the design and execution of laminated gypsum board systems.

Russia: Saint-Gobain has announced plans to build a 50,000t/yr-capacity stone wool plant in Siberia. The company says that the decision aims to help it better meet the growing needs of consumers in Siberia, Kazakhstan and the Far East. It will produce the insulation material using basalt. The total estimated cost of the project is around US$35m, with commissioning scheduled for 2023.

Russia, Ukraine and Commonwealth of Independent States regional chief executive officer Antoine Peyrude said, “The new production complex will allow us to better respond to the demands of the local market, whose demand for innovative energy-efficient solutions is constantly growing.”

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.”
