Insulation industry news from Global Insulation

UK: SIG recorded US$1.81bn in sales in the first half of 2023, up by 5% year-on-year from US$1.73bn in the first half of 2022. The group noted a decline in its sales volumes, partly offset by positive tailwinds from cost inflation in the comparison period. Its profit after tax declined by 70% to US$5.98m from US$20.2m.

CEO Gavin Slark said “Our performance in the first half of 2023 reflects the challenging market conditions we are currently facing, with the group’s like-for-like revenue growth flat year-on-year. Despite these conditions, I’m very pleased with the progress we are making on many fronts to improve the business notably with the initiatives across our operating companies to improve our ability to drive higher levels of profitable growth when market conditions recover." Slark continued “Looking ahead, while we expect market conditions in the second half of 2023 to remain difficult, we remain confident the business will grasp the opportunities it has to continue to improve its underlying operational performance. This will, in turn, deliver higher levels of profitability as we drive towards our medium-term margin target of 5%. The group is financially and commercially well placed to drive meaningful shareholder value in the medium and long term.”

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: Belgium-based Etex has concluded a deal to acquire glass wool insulation producer Superglass. Superglass operates the Stirling glass wool insulation plant in Stirling, Scotland, and employs 200 people. Etex says that the acquisition will increase its number of employees in its insulation division, which operates 11 plants across Europe, to 1500, and its total UK-based employees to 1300. Etex already produces gypsum wallboard, fibre cement sidings and slates and fibre cement corrugated sheets in the UK.

CEO Bernard Delvaux said “Etex has a clear focus to be the most innovative and sustainable global lightweight building material manufacturer. Joining forces with Superglass today is a great step forward on our growth path in insulation, just one year after we acquired URSA. The need for energy efficient and sustainable buildings is crucial, and Superglass and URSA are a perfect answer for it.”

Belgium: Recticel has launched a new range of polyurethane insulation board products that contain 25% bio-circular raw materials. The new ‘Impact’ range reduces CO₂ emissions by an average of 43% compared to a standard board while offering equivalent insulation performance. These new products are an important element of Recticel's proactive approach to reaching net zero emissions by 2050, as committed to the Science Based Targets initiative (SBTi).

The Belgium-based insulation producer also completed its divestment of its Engineered Foams division in mid-June 2023. The bulk of the business was sold to US-based Carpenter Co for an enterprise value of around Euro454m with two UK-based units sold to GIL Investments, as part of the competition clearance provided by the UK Competition & Markets Authority (CMA). Following the divestment of its Engineered Foams division, Recticel has become solely an insulation manufacturer.

UK/Ireland: Knauf Insulation UK & Ireland has launched ‘OmniFit Slab 32’, a 32 lambda glass mineral wool insulation slab product for use in light steel frame systems (SFS) as part of a rainscreen façade or other external wall build-ups.

Liliya Luke, the Glass Mineral Wool Product Manager at Knauf Insulation, said “We have launched OmniFit Slab 32 to help our customers deliver the low U-values required, without compromising on fire safety, acoustic performance or sustainability.” He added, “Specifiers can now optimise their rainscreen façade systems by adding the benefits of glass mineral wool to their build-up - delivering acoustic performance, and reduced embodied carbon compared to rock-only solutions, with an insulation specification that remains completely non-combustible.”

The new product is primarily designed for use with ‘Rocksilk RainScreen Slab’ when used in rainscreen applications, and is suitable for use in the external wall systems of all residential buildings over 11m tall and relevant residential buildings over 18m tall. It is the latest addition to Knauf Insulation's OmniFit range of glass mineral wool roll and slab products.

Ireland: Kingspan recorded sales of US$2.21bn during the first quarter of 2023, up by 4% year-on-year from first-quarter 2022 levels, Reuters has reported. The producer said that group insulation sales remained in line year-on-year. Insulated panel sales remained ‘sluggish,’ but constituted 25% of all orders. By region, sales were ‘strong’ in the Americas and ‘solid for the most part’ in Western Europe, while conditions ‘remained tough’ in Central and Eastern Europe. Kingspan forecast first-half earnings of US$441m in 2023.

The company proposed its future delisting from the UK-based London Stock Exchange, where it says current share trading is ‘negligible as percentage of total trading.’

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: The Peatland Progress bog restoration project in Cambridgeshire will plant and harvest bulrushes for use as a raw material in alternative insulation production. The Evening Standard newspaper has reported that trials have successfully produced insulation from bulrushes in Germany and the Netherlands. Peatland Progress holds Euro9.08m in National Lottery funding. The project will rewet peat and restore wetland habitats over 120 hectares of the historic Fens.

UK/Ireland: Knauf Insulation has appointed Ross Foreman as its National Wood Wool Manager for UK & Ireland. Foreman will support the company’s drive to meet increasing demand for its Heraklith range of wood wool products.
