Insulation industry news from Global Insulation

Canada: Saint-Gobain completed its acquisition of Building Products of Canada at the start of September 2023 for an undisclosed sum. The privately-owned company manufactures residential roofing shingles and wood fibre insulation panels. It has 460 employees and three manufacturing plants, at Montreal in Quebec, Edmonton in Alberta and Pont-Rouge in Quebec. Saint-Gobain says that the purchase is intended to establish its position worldwide in light and sustainable construction. The acquisition was first announced in June 2023.

Canada: The Competition Bureau of Canada has cleared France-based Saint-Gobain to acquire Building Products of Canada. Building Products of Canada produces wood fibre insulation panels, among other materials for construction. Saint-Gobain says that the company complements its subsidiary CertainTeed Canada’s existing operations. It expects to complete the acquisition on 1 September 2023.

Denmark: Saint-Gobain’s subsidiaries Isover and Leca have started an agreement with waste management company Norrecco to recycle glass wool insulation. Under the new system, contractors will be able to return used and excess Isover glass wool to Norrecco's waste treatment stations at Prøvestenen in Copenhagen and at Agerskov in Southern Jutland. Norrecco will then pass the glass wool to Leca Denmark’s plant at Hinge near Randers. Here it will be used as a raw material in the production of lightweight expanded clay aggregate (LWA) products. LWA is used in a variety of applications such as insulation or as a structural filler. Leca added that LWA can be recycled repeatedly.

Mona Ammitzbøll Rasmussen, the Sustainability Engineer at Saint-Gobain Denmark, said "From the moment our glass wool leaves the factory, we want to support the idea that the material will one day return and be used in the production of new insulation materials, rather than ending up in landfills. It is an unnecessary waste that we need to eliminate as soon as possible."

Leca Denmark has the capacity to accept around 1000t/yr of used or excess glass wool from the Danish market. The company said that, although it represents a small portion of the total production, it reduces the need to extract a corresponding amount of natural clay, which is the primary raw material in its Leca LWA product. Isover is also working on publishing guides to better help contractors sort between the different types of mineral wool to assess purity ahead of potential recycling.

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."

Canada: Saint-Gobain has entered into a definitive agreement to buy Building Products of Canada for around Euro925m in cash. The privately owned company manufactures residential roofing shingles and wood fibre insulation panels. The acquisition is intended to reinforce Saint-Gobain’s position in light and sustainable construction in the Canadian market. Closure of the transaction is subject to customary conditions and expected by the end of 2023.

Benoit Bazin, chief executive officer of Saint-Gobain, said “This is an important and logical step for Saint-Gobain, allowing us to establish a leading position in roofing in Canada, completing our offering for the building envelope which we have reinforced with the recent Kaycan and GCP acquisitions. It completes our offering of solutions for light and sustainable construction in Canada as we have done successfully in the US.”

Europe: Knauf Insulation has joined Daikin, Danfoss, Rockwool, Saint-Gobain, Signify and Velux to promote building energy efficiency in Central and Eastern Europe (CEE). The six companies have signed a memorandum that commits them to work together to encourage cooperation and allocation of ‘personal and financial resources’ on a country level to establish and maintain national associations equipped with the expertise to engage in public debates effectively and the skills to inspire better policies.

Radek Bedrna, Knauf Insulation’s managing director for Eastern Europe and Middle East, said “This memorandum is a powerful commitment to tackle the building and energy challenges facing CEE. It will provide the campaigning initiatives with the needed support to drive the policy changes that will be transformational for building renovation in the region.” He added that the region has five out of seven European Union (EU) countries with the highest gas saving potential arising from insulating residential buildings. Two thirds of the 43.6m homes in single- and multi-family house in the CEE region were reportedly built before 1989 and are energy inefficient.

The companies signed the document at the Central and Eastern European Energy Efficiency Forum (C4E) in late May 2023. The forum, which brought together more than 240 public authority representatives with advocacy groups, non-government organisations (NGO) and private companies, called on policy makers to roll out well-designed subsidy schemes with a long-term outlook.

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.

India: Saint-Gobain has entered into an agreement to acquire Indian market leader glass wool insulation producer Twiga Fiberglass, local press has reported. Twiga Fiberglass has produced insulation as a licensee of Saint-Gobain's glass wool insulation technology since 2005.

Saint-Gobain previously acquired stone wool insulation producer Rockwool India in February 2022.

US: Saint-Gobain North America has started a program where windshield glass scraps are recycled and reused in the production of insulation. Waste glass from the company’s Saint-Gobain Sekurit’s unit at Garden Grove in California is sent to CertainTeed Insulation’s facility at Chowchilla, where it is use to make fibreglass insulation. Saint-Gobain is working with Shark Solutions on the project. The initiative started earlier in 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.
