Insulation industry news from Global Insulation

UK: The government has accepted the recommendations of a public inquiry into the Grenfell Tower disaster, in which 72 people died in a fire that spread through exterior cladding systems in a residential block in London. The Guardian newspaper has reported that the inquiry recommended actions against seven different organisations that share in responsibility for the spread of the deadly fire. The inquiry's final report named these organisations as Kingspan Insulation, Saint-Gobain Construction Products, Harley Facades and testing company Exova Group, along with aluminium and bonded sheets producer Arconic Architectural Products, property development and management company Rydon Maintenance and architecture firm Studio E Architects. Additionally, the report recommended the introduction of a unified regulatory body for the construction industry and the consolidation of fire safety matters under the Department of Housing, Communities and Local Government.

Deputy Prime Minister Angela Rayner said "The final report exposed in stark and devastating detail the shocking industry behaviour and wider failures that led to the fire, and the deep injustices endured by the bereaved, survivors and residents.”

UK Shadow Housing and Communities Secretary Kevin Hollinrake told Parliament that criminal charges against those responsible must follow ‘where evidence allows.’

UK: Denmark-based Rockwool has acquired external thermal insulation composite systems producer Wetherby Building Systems. Reuters has reported that the newly acquired company will now operate as part of Rockwool Wall Systems, under the name Wetherby Wall Systems. The integration parallels that of previous Rockwool acquisitions in other markets, like Fast Wall Systems in Poland and Heck Wall Systems in Germany.

Rockwool CEO Jes Munk Hansen said “The share of stone wool insulation in the Wetherby business has been growing steadily, and we will be completing this transition to a fully stone wool-based portfolio, as we have done in other markets in the past.” He added that this will advance Rockwool’s transformation of the construction sector towards non-combustible façades.

Wetherby Building Systems managing director Bob Deane said “There is a long-standing relationship between Wetherby and Rockwool, and the match is strong on all significant drivers.”

UK: The six-year public inquiry into the Grenfell Tower fire, which claimed 72 lives in 2017, has issued its final report, finding fault with ‘dishonest’ companies, as well as former governments and a disorganised response from the fire service. The inquiry criticised the role of cladding manufacturers, notably US-based Arconic, for its ‘systematic dishonesty’ in concealing the true fire hazards of its products. Arconic, which produced the Reynobond 55 polyethylene cladding used on Grenfell Tower, was accused of having hidden ‘very poor’ fire safety test results from the public and certification bodies. In the report, the cladding is described as ‘extremely dangerous’ when used in folded cassette form, and was ‘by far the largest contributor’ to the Grenfell fire.

The inquiry also named both Celotex and Kingspan as contributors to the incident. Celotex was accused of making ‘false and misleading claims’ by presenting its product to cladding contractor Harley Facades as being safe and suitable for Grenfell, even though ‘it knew that was not the case.’ Insulation producer Kingspan reportedly ‘misled the market’ by not revealing the limitations of its product, which was used on a small section of the building. In response to these findings, the inquiry has called for a revision in testing materials and designs for fire safety, advocating for transparency by making these test results publicly accessible. The findings of this inquiry lay the groundwork for potential criminal charges, with police and prosecutors indicating that investigations will continue until the end of 2025, and decisions on criminal charges expected by the end of 2026, according to a report by the BBC.

Kingspan said in a statement “We welcome the publication of today’s report which is crucial to a public understanding of what went wrong and why. It explains clearly and unambiguously that the type of insulation (whether combustible or non-combustible) was immaterial, and that the principal reason for the fire spread was the PE ACM cladding, which was not made by Kingspan. Kingspan has long acknowledged the wholly unacceptable historical failings that occurred in part of our UK insulation business. These were in no way reflective of how we conduct ourselves as a Group, then or now. While deeply regrettable, they were not found to be causative of the tragedy and Kingspan has already emphatically addressed these issues.”

A spokesperson for Celotex said “The publication of the Grenfell Tower Inquiry report marks the conclusion of the inquiry’s work and we are considering its contents with care. This review was a significant and thorough undertaking, and the results of that work were disclosed promptly and proactively to relevant stakeholders, including the Grenfell Tower Inquiry. Independent testing commissioned following the review demonstrated that the cladding system described in the Celotex RS5000 marketing literature met the relevant safety criteria. That system was substantially different to that used at Grenfell Tower. Decisions about design, construction and the selection of materials for the Tower were made by construction industry professionals.”

A spokesperson for Arconic subsidiary Arconic Architectural Products (AAP), which Building News reports supplied aluminium composite material used for the rainscreen at Grenfell Tower, said “The company respects the Inquiry process. AAP cooperated fully with the work of the Inquiry and will continue to engage with further legal processes. Together with other parties, AAP has made financial contributions to settlements for those affected, as well as to the restorative justice fund. Throughout the Inquiry, AAP has maintained a number of points: AAP sold sheets of aluminium composite material as specified in the design process. This product was safe to use as a building material, and legal to sell in the UK as well as the more than 30 other countries in which AAP customers purchased the product. We reject any claim that AAP sold an unsafe product. AAP regularly conducted tests of its materials using third-party testing bodies. Reports on these results were all publicly available, and AAP made these reports available to its customers. AAP did not conceal information from or mislead any certification body, customer, or the public.”

South Korea: The Ministry of Land, Infrastructure and Transport has suspended the Korea Foamed Plastic Industry Cooperative’s standard for expanded polystyrene (EPS) insulating sandwich panels. The standard had been certified by the Korea Institute of Civil Engineering and Building Technology. Maeil Business Newspaper has reported that the suspension is part of a regulatory revision in the interest of fire safety. The value of the South Korean EPS sandwich panel industry is US$1.37bn/yr.

The Korea Foamed Plastic Industry Cooperative said “With a severe shortage of certification agencies, it takes over a year to obtain certification. This is tantamount to telling small businesses to shut down.”

UK: Recticel says that new requirements following the UK’s exit from the EU have created estimated extra one-time costs of Euro464,000. Local press has reported that UK-based laboratory testing is estimated to cost Euro325,000 across eight products, while new fire tests for the same products will add a further Euro130,000.

Senior technical manager Simon Blackham said “It’s the same standards, to the same test method, the same everything - and it would have to be paid for, ultimately, by the customer.”

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.
