Insulation industry news from Global Insulation

Belgium: Huntsman Polyurethanes has launched its DaltoPIR XHFR product for composite panels. The polyisocyanurate (PIR) insulation product was introduced at a panels and profile conference in Greece.

The product uses DaltoPIR insulation technology to offer a different viscosity build up in rising foam. The company says that this enables more stable and more consistent processing, which in turn can help panel producers achieve better panel planarity and quicker line speed. The resulting foam has very low friability, which Huntsman says contributes to the long-term properties of the panels.

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: 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.

UK: The British Rigid Urethane Foam Manufacturers’ Association (BRUFMA) has said that the materials tested so far by BRE Group, following the Grenfell fire in June 2017, do not meet building regulations and would never be recommended or approved for use by the members of BRUFMA in a real building.

The Department for Communities and Local Government (DCLG) has commissioned six BS 8414 tests using a combination of materials, including the make-up of the outer cladding system. The first aluminium composite material (ACM) cladding test, carried out by BRE combined an assembly of polyisocyanurate (PIR) insulation used in conjunction with an unmodified polyethylene filled ACM cladding panel. Both PIR foam and mineral wool are being tested with each cladding system.

BRUFMA described the situation as ‘worrying’ that a number of buildings have been identified with this combination, indicating a lack of compliance to existing rules and regulations. However, it has advised that all six tests should be completed satisfactorily before any analysis is drawn and remedial action is proposed by the government. It also highlighted that PIR insulation manufactured in the UK and Ireland that is recommended for use in high-rise buildings is tested with the BS 8414 fire test as part of a complete ventilated rainscreen system.

UK: Celotex has stopped supplying its RS5000 polyisocyanurate foam (PIR) insulation board product in rainscreen cladding systems for buildings over 18m tall. The decision is a temporary one whilst an investigation into the Grenfell Tower fire continues. The subsidiary of Saint-Gobain previously confirmed that its product was purchased for use in a refurbishment project at the building. The fire is believed to have killed 79 people.

The insulation producer said that safety testing had been undertaken on its RS5000 product as part of a ‘particular’ rainscreen cladding system. It added that, “…any changes to components of the cladding system or construction methods used need to be considered by the relevant building designer.”

The decision by Celotex follows an announcement by the Metropolitan Police that insulation samples collected from Grenfell Tower combusted quickly in tests. The authorities are examining aluminium composite tiles, the insulation behind it and how these tiles were fixed to the building as well as how they were installed. The aluminium composite tiles have also failed initial safety tests.

UK: Belgium’s Recticel plans to invest at least Euro20m towards increasing its production capacity by at least 50% of rigid polyurethane foam (PIR) panels for thermal insulation for the construction market. Start of production is planned for the third quarter of 2018. The polyurethane foam producer plans to take advantage of stricter insulation standards and regulations, higher energy prices and the growing market awareness for the product.

“This investment is consistent with the growth strategy of our Insulation business. It brings substantial additional production capacity to enable Recticel to continue to serve its customers in the United Kingdom and to grow with them,” said chief executive officer Olivier Chapelle.

UAE: Kingspan Insulation has started manufacturing its PalDuct Hydro System product, panels with a polyisocyanurate (PIR) insulation core faced with aluminium foil, at its plant in Dubai. The company has changed its manufacturing process by installing a pentane tank at the plant to make the product, according to Gulf Construction. The panels have a density of 48 - 50kg/m³ and in a thickness of either 20mm and 30mm. A company spokesman said that the product can be specified by engineers for projects required to comply with local regulations such as a Estidama in Abdu Dhabi.

Russia: TechnoNicol plans to launch production of its polyisocyanurate (PIR) foam insulation plant in the Ryazan region on 24 May 2016. The new plant will have a production capacity of 30Mm². Investment in the project amounts to Euro22.6m according to local press. The plant was originally scheduled for launch in the autumn of 2015.
