Insulation industry news from Global Insulation

Slovenia: A fire broke out at Fragmat’s insulation plant at Podskrajnik near Cerknica on 13 June 2019. Around 450 fire fighters were involved in controlling the blaze, according to the Slovenian Press Agency. The unit manufactures polystyrene insulation.

US: Celotex has been named in a lawsuit filed in Philadelphia on behalf of victims and families of the 2017 Grenfell Tower fire in London, UK that killed 72 people. Attorneys for the plaintiffs said they represent the estates of 69 of the 72 people who perished in the residential high-rise fire, and 177 survivors who suffered life-altering injuries, according to Reuters. The lawsuit demands a jury trial but has not specified the amount of compensation it is seeking. Whirlpool and Arconic have also been named in the document.

Slovenia: A fire has caused damage to Knauf Insulation’s Škofja Loka mineral wool plant. The fire started in a warehouse before spreading on 2 February 2019 before it was extinguished, according to the Slovenian Press Agency. No injuries were reported during the incident. The cause of the blaze is being investigated.

UK: The UK government plans to adopt the recommendations made by Dame Judith Hackitt in her review of building regulations and fire safety published following the Grenfell Tower fire in mid-2017. Other commitments the Ministry of Housing, Communities & Local Government has made include creating a new regulatory and accountability framework to provide greater oversight of the industry and introducing clearer standards and guidance, including establishing a new Standards Committee to advise on construction product and system standards and regulations. It says it will place residents at the heart of the new system, with new routes for engagement and redress, and that it wants to help create a culture change and a more responsible building industry. In addition to setting out its plans to implement the changes called for by Hackitt, the government says that a full review of fire safety guidance within building regulations has also been launched.

UK: An investigation by the BBC’s Panorama news program has alleged that a safety test for Celotex’s RS5000’s polyisocyanurate foam (PIR) insulation board product used extra fire retardant in safety tests. The programme believes that a different product was eventually sold to the public. It also accused the subsidiary of Saint-Gobain of mis-selling the insulation with misleading marketing.

Celotex said that it was unaware of this allegation and had not identified anything that would support it. It is investigating this allegation as a ‘matter of urgency.’ It added that it had not used any special formulation for a recent successful BS-8414 system test in May 2018 or Class 0 fire testing.

Celotex suspended supply of RS5000 PIR insulation board in June 2017 following its use as part of the rainscreen cladding system in the refurbishment of Grenfell Tower. The building had a fire in June 2017 that killed 72 people.

UK: A review by the government into building regulations and fire safety has found that the local buildings regulation system is broken, However, it has not recommended a ban on combustible cladding, according to Reuters. The independent review followed a fire at a residential tower block in June 2017 that killed 71 people. An aluminium cladding with a flammable plastic core is thought to have contributed to the rapid spread of the fire.

Judith Hackitt, the engineer and former Chair of the UK Health and Safety Executive presiding over the review, defended existing regulations and blamed poor implementation of the rules by builders and contractors. She has recommended that the building regulations system be changed to focus on high-rise residential buildings first and then to improve building safety during design, constriction and refurbishment. She also called for greater enforcement powers with ‘serious’ penalties for individuals who infringe the rules.

Organisations including Kingspan Insulation, Knauf Insulation, the Mineral Wool Insulation Manufacturers Association and the Constructions Products Association provided written evidence to the review.

A separate public inquiry is examining the causes of the Grenfell Tower fire and a police investigation is also looking at the incident.

UK: Celotex says that a rainscreen cladding system using its RS5000 polyisocyanurate foam (PIR) insulation board product has passed the BS 8414:2 safety test. The insulation producer previously announced in January 2018 that it had found errors between a previous test and the description of the system in the report of the test. It added that the rainscreen cladding system conformed to the BR 135 fire test. It is now notifying the relevant bodies and is contacting its customers about results of this latest test.

Celotex suspended supply of RS5000 PIR insulation board in June 2017 following its use as part of the rainscreen cladding system in the refurbishment of Grenfell Tower. The building had a fire in June 2017 that killed 71 people. The suspension remains in place.

UK: A leaked report by the by fire investigation specialists BRE Global has blamed a poor cladding refurbishment on a lethal fire at the Grenfell Tower in London on 14 June 2017. The document, leaked to the Evening Standard newspaper, found multiple deficiencies in the installation of the windows, cavity barriers and cladding system, and their failure to meet building regulations.

The report described insulation used in the refurbishment as ‘combustible’ and said that it provided a medium for the fire to, ‘spread up, across and within sections of the façade.’ BRE noted that the 75mm insulation foam used on most of the spandrel beams had, ‘no markings to identify the manufacturer of the foam.’ The Evening Standard says that 100mm Celotex foam insulation was also used in the columns but that the BRE report does not further distinguish between the two types.

71 people were killed in the fire that took place on 14 June 2017. The draft BRE report was submitted to the Metropolitan Police Service as part of its investigation.

UK: Celotex has found errors in a safety test for its RS5000 polyisocyanurate foam (PIR) insulation board product that was used as part of the rainscreen cladding system in the refurbishment of Grenfell Tower. As part of a review of the product the company has determined that there were differences between the system as tested for BS 8414:2 and the description of that system in the report of the test. The BS 8414:2 safety test was originally conducted prior to the RS5000 product being launched.

The insulation producer is exploring whether any safety issues arise from the differences in the test. It says it has notified the relevant bodies and is contacting its customers.

“It is a matter of real regret for us that this issue has arisen: we fully recognise its potential seriousness and that it will give rise to concern. We are working hard to arrange the further testing as quickly as possible and we will make a further announcement once the results of that testing are available,” said Celotex in a statement.

Celotex suspended supply of RS5000 PIR insulation board in June 2017 following a fire at Grenfell Tower in London that killed 71 people.

UK: Gene Murtagh, the chief executive officer (CEO) of Kingspan Group, has called for a number of changes to be made to fire safety regulations for buildings in the UK. He called for large-scale testing under BS8414 to be extended to cover all cladding systems, a strengthening of the way desktop studies are used in fire safety compliance, improved training for installers of building facades and better control of fire safety through the design and construction process of buildings. His comments were made to Building Magazine following the Grenfell Tower fire in June 2017 and at the start of the Public Inquiry into the incident.

“So far as I am aware, polyethylene (PE) cored Aluminium Composite Materials (ACM) have never been successfully tested in a cladding system in a manner consistent with building regulations so it is hard to understand how this product ever ended up on Grenfell Tower,” said Murtagh. “Similarly, given the fire performance characteristics of these ACM cladding panels, it is no surprise in my view that they performed so poorly in combination with a range of insulation types in the recent series of large-scale tests by the Department for Communities and Local Government (DCLG).” said Murtagh added that fire safety is an ‘extremely complex’ field and that any investigation needs to consider a wide range of factors.

The majority of the insulation purchased for use in a refurbishment of Grenfell Tower prior to the fire was Celotex’s RS5000 polyisocyanurate foam (PIR) insulation board. However, Kingspan confirmed in July 2017 that a small amount of its Kooltherm K15 phenolic insulation product had also been used without its knowledge and that it had no involvement in the design or specification of the refurbishment.
