Insulation industry news from Global Insulation

UK: Testing provider the Building Research Establishment (BRE) has informed Kingspan and Saint-Gobain subsidiary Celotex of its decision to break off its relationship with them due to perceived 'reputational risk.' Insulation supplied by Kingspan (Kooltherm K15 phenolic insulation) and Celotex (RS5000 polyisocyanurate insulation) was present in Grenfell Tower, London, when it burned down in June 2017. 72 people died in the fire. Both producers deny having contributed to the disaster. The Grenfell Tower Inquiry investigated the relationship between each company and the BRE during its inquest into the fire. A final report is currently in preparation following the conclusion of Phase 2 hearings in 2022.

The Grenfell Tower Inquiry heard that Kingspan had marketed its Kooltherm K15 panels for general use in high rise construction, relying on tests carried out at a BRE facility with a system involving external fibre cement panels, of a sort not used in Grenfell Tower. Subsequent tests of the product, carried out by Kingspan, included one which resulted in a 'raging inferno.' Meanwhile, Celotex added fire-resistant board to a rig used in testing in 2014, reportedly to increase its products' chances of passing.

Inside Housing News has reported that BRE said “BRE no longer accepts any new work on behalf of Kingspan or Celotex following evidence heard during the course of this inquiry.”

Kingspan clarified that "There is no product performance basis for [BRE's] decision,” adding that its panels had shown zero non-conformities in their most recent audit in December 2022. It said “Independently of BRE, whose certification is regionally focused on the UK and Ireland, Kingspan is certified by the globally recognised insurer testing regime FM Approvals, which carries out annual factory surveillance audits to verify our products comply with its global approval standards."

UK: Around 900 people have reached a settlement at the High Court related to civil claims following the fire at Grenfell Tower in 2017. A total settlement figure of Euro170m has been set by the court, according to ITV News. However, the civil claim will have no determination on the ongoing public inquiry into the fire and any potential future criminal charges.

Both cladding company Arconic and insulation producer Celotex have been part of the various civil legal cases. Celotex, a subsidiary of Saint-Gobain, said that “without admission of liability” it had agreed to make a financial contribution towards the settlement. It added that, “Celotex and the Saint-Gobain Group reaffirm their deepest sympathies to everyone affected by the fire.” Kingspan has also confirmed its involvement in civil cases relating to the fire at Grenfell Tower in a statement reported upon by Building magazine.

UK/Ireland: The UK Housing Secretary Michael Gove has invited Ireland-based Kingspan to enter into discussions over a possible contribution by the company towards fire safety renovations on unsafe buildings across the UK. Following the deadly Grenfell Tower fire of June 2017, extensive UK housing stock was found to be unsafe due to the presence of flammable materials in exterior insulation systems. In an open letter, Gove said “Those companies who do not share our commitment to righting the wrongs of the past must expect to face commercial consequences.”

The Irish Times newspaper has reported that Kingspan previously said that it would contribute to 'an appropriate joint government and industry-wide funding mechanism' for the policy. Kingspan's Kooltherm K15 phenolic insulation accounted for 5% of Grenfell Tower's insulation. Kingspan clarified that it was not responsible for the supply of the insulation used in construction of the tower.

UK: Graffiti reading 'Grenfell' has appeared on walls and gates at the entrance to Ulster Rugby's Kingspan Stadium in Belfast in protest against Kingpan's indirect involvement in the Grenfell Tower fire in London on the night of 13 - 14 June 2017. Some insulation produced by Kingspan was present in the building envelope of the tower at that time.

The Belfast Telegraph newspaper has reported that local groups Act Now and Uplift in the Republic, in partnership with Britain-based 38 Degrees, previously erected a billboard in view of the Kingspan Stadium, expressing solidarity with victims of the Grenfell Tower disaster, in March 2022.

UK: Insulation and cladding companies have blamed each other in a public inquiry investigating the Grenfell Tower Fire that took place in 2017 that led to 72 deaths. During closing statements to the inquiry the Press Association reports that the legal representation for Ireland-based Kingspan said, "In its phase one report the inquiry concluded that the cladding system on Grenfell Tower did not comply with the building regulations and that the PE ACM [polyethylene cladding] manufactured by Arconic was the principal reason for the rapid fire spread." The lawyer went on to summarise that Kingspan’s Kooltherm K15 phenolic insulation product was safe when used appropriately and not relevant to the nature and speed of the spread of the fire in this instance.

In a written statement though Arconic blamed the cause of the fire upon the failure by those involved in the refurbishment of the tower in assessing the fire performance of the building materials used and their configuration. It added, "A failure which was in significant part the result of the efforts made by the manufacturers of the insulation, Celotex and Kingspan, to hide or downplay the combustible and hence (under the prevailing regulatory regime) non-compliant nature of their product, an awareness of which would otherwise and in any event have led inexorably to the choice and configuration of the components being re-visited and amended."

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.

UK: Michael Gove, the Secretary of State for Housing, Communities and Local Government, has told parliament that the government intends to make building materials producers and developers pay to fix all fire-safety issues at high-rise buildings. In a statement Gove said, “We will make industry pay to fix all of the remaining problems and help to cover the range of costs facing leaseholders. Those who manufactured combustible cladding and insulation, many of whom have made vast profits even at the height of the pandemic, must pay now instead of leaseholders.” Flat owners in buildings over 11m tall will no longer be forced to pay for their own repairs under the proposed plans, according to the Times newspaper. Manufacturers and developers face a potential Euro4.8bn bill for the remedial work.

UK: Leeson Polyurethanes’ adhesive and coatings plant in Leamington Spa, Warwickshire caught fire following a series of explosions on the morning of 27 August 2021. Worcester News has reported that one person known to have been working in the plant at the time remains unaccounted for on 31 August 2021. Emergency services extinguished the blaze but have been unable to enter the site so far. The smoke cloud from the fire was visible over 60km away. It resulted in an evacuation of neighbouring residential streets.

UK/Ireland: Kingspan UK head of insulation boards Peter Wilson will retire from the company at the end of 2020. Wilson will also step down from his position on the producer’s board of directors.

Chief executive officer (CEO) Gene Murtagh has also apologised for ‘process shortcomings’ that have been highlighted by the ongoing Grenfell Tower Inquiry. The Irish Times newspaper reports that the company used flawed safety tests to market its Kooltherm K15 insulation product, some of which was used on the building. Murtagh used his Christmas 2020 address to staff to pledge trust-rebuilding action. He said that the company will treat the issues raised in the inquiry with the ‘utmost seriousness.’

In other personnel changes, Alan Lawlor has been appointed Divisional Managing Director of Kingspan's Insulation Boards Division with responsibility for its global activities. He is currently chief financial officer of Kingspan's Insulation Boards Division and managing director of Kingspan Insulation, Southern Europe.

Jim Carolan has been appointed as Group Head of Compliance & Certification with immediate effect, reporting to the Group chief executive officer (CEO). The group said that in this newly created role he will be responsible for ensuring a rigorous approach to certification, testing and product compliance across all Group divisions. Carolan's prior role was as Operations Director in Kingspan's Insulated Panel's Division.

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.

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.
