Insulation industry news from Global Insulation

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: Kingspan has confirmed that a limited amount of its Kooltherm K15 phenolic insulation product was used in Grenfell Tower. In response to a report by Channel 4 News the insulation producer said that a ‘very small quantity’ of the product had been used without its knowledge in a façade refurbishment of the high-rise tower. The building subsequently suffered a fire in June 2017 in which at least 80 people are believed to have died or gone missing.

“Kingspan had no involvement in either the design or the specification of the refurbishment of the Grenfell Tower facade, and neither Kingspan insulated panels nor Kingspan façade systems were used on Grenfell Tower,” said Kingspan in a statement. It added that following the fire it became aware that a limited quantity of Kingspan Kooltherm K15, less than 5% of the estimated total amount of insulation used on the building façade, was sourced by a third party distributer and supplied to contractors involved in the refurbishment. It impressed that, “It appears that Kooltherm K15 has been used without our knowledge, as part of a combination for which it was not designed, and which Kingspan would never recommend.”

The majority of the insulation purchased for use in the building refurbishment was Celotex’s RS5000 polyisocyanurate foam (PIR) insulation board. This product has been stopped for use in rainscreen cladding systems for buildings over 18m tall whilst the investigation into the Grenfell fire continues.

UK: SIG’s revenue grew by 8.1% to Euro1.6bn in the first half of 2017 due to favourable currency exchange rates and sales in Mainland Europe. Sales in Mainland Europe rose by 42% in the period boosted by recovery in the construction markets particularly in France.

UK: The British Rigid Urethane Foam Manufacturers’ Association (BRUFA) has warned against ‘misleading’ claims being made in relation to the Grenfell Tower fire ahead of a government investigation. In a statement the body for the rigid polyisocyanurate (PIR) and polyurethane (PUR) Insulation Industry in the UK said it would challenge and correct any misleading allegations about the incident and provide information to assist an ‘accurate’ analysis. It added that the PIR and PUR insulation industry is an established and responsible one with a usage of over 50 years in the construction sector.

“We have a growing concern that misleading claims, supported by selective data are gaining traction and being reported as facts. If this supposition takes hold before the enquiry has established the truth of the matter, there is a danger it will lead to the wrong conclusions and decisions, that will do nothing to improve the future safety of buildings, including high-rise tower blocks. It may also lead to behavioural changes that could be detrimental to the future welfare of the built environment,” said BRUFA.

The UK government has appointed Martin Moore-Bick, a former judge, to head the public inquiry into the fire. As well as investigating the incident, the inquiry is expected to recommend changes to national building regulations.

UK: Exterior cladding systems have come under scrutiny in the aftermath of a devastating fire at a tower block in west London that has killed at least 17 people. The system was retrofitted in 2016 to the 24-storey building that was originally built in the 1970s, according to Reuters. Concerns have been raised about the speed the fire spread. Suspicions have targeted the flammability of the insulation panels used in the façade and whether fireproof barriers were installed properly at the site. It is believed that wall fixings, exterior zinc panels and insulation panels were used in the cladding according to a planning document relating to the building that was published by the local government in 2012. It is unknown whether the insulation material included any fire retardant chemical additives.

“Without knowledge of the specific materials used we cannot say at this early stage if any of the conclusions above are relevant to this tragic incident, but the increasing use of combustible materials in construction needs to be addressed if further events are to be avoided,” said Jim Glockling, Technical Director at the Fire Protection Agency (FPA). He added that the FPA believes that local building regulations need to be updated to consider, “both the external envelope of the building and its resilience to fire ingress.”

Prime minister Theresa May has ordered a full public inquiry into the incident.

UK: The British Board of Agrément (BBA) has given its approval to Rockwool’s Rainscreen Duo Slab façade insulation product. It is the first stone wool product to gain this for use in ventilated rainscreen systems. As part of the certification process the product was tested for factors such as thermal performance, condensation risk, behaviour in relation to fire, and durability in order to meet national regulations. Rainscreen Duo Slab has achieved certification status for use as a Hybrid frame system and Rainscreen system.

“It is incredibly important to us to put our products through the BBA process, as the certification provides architects with peace of mind when specifying our products” comments Paul Barrett, Product Manager at Rockwool.

Rainscreen Duo Slab is a dual density insulation board that offers weather resistance on its outer surface whilst being installed and an inner surface that is designed to accommodate the substrate to which it is being applied. It is fire resilient and complies with Approved Document B, achieving the Euroclass classification: A1. It also complies with BR135: Fire Performance of External Insulation for Walls of Multi-Storey Buildings.

UK: Texas’ Huntsman Corporation has completed its acquisition of IFS Chemicals, a manufacturer of methylene diphenyl diisocyanate (MDI) based systems. The purchase price has not been disclosed.

“With its highly experienced team and loyal customer base, IFS provides us with excellent access to the UK’s growing downstream MDI systems market. It will serve as a strategic platform to expand our business and consolidate our position as a market leader. The acquisition represents the latest step in our plan to strengthen our differentiated downstream capabilities and we now have more than 25 facilities worldwide, reflecting our confidence in the long-term growth prospects for MDI-based urethanes, ” said Tony Hankins, president of Huntsman’s Polyurethanes division.

UK: Knauf Insulation has entered into a long-term contract with Veolia to support the construction of a glass cullet-processing unit next to its insulation production plant in St Helens, Merseyside. The unit will be constructed and operated by Veolia on land owned by Knauf Insulation. It will provide recycled glass for use in Knauf’s insulation products. Veolia has invested Euro11.6m into the unit it plans to build by the end of 2017.

“We are delighted to be working with Veolia on this project, which perfectly aligns our goals for sustainability and the circular economy. Given recent shortages impacting the construction sector, our customers can be reassured that we are working proactively upstream to further enhance the security of our supply,” said John Sinfield, managing director at Knauf Insulation Northern Europe.

The new facility will dry and refine glass into a ‘furnace ready cullet’, a recycled standard of glass that has been cleaned and crushed into small fragments. The cullet is then fed into a furnace where it is melted and spun into glass mineral wool.

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.

UK: The British Rigid Urethane Foam Manufacturers' Association (BRUFMA) has called for the government to ensure that any new house building campaigns deliver energy efficient buildings and continue to increase the building standards for the sector. BRUFMA was responding to the publication of a White Paper or government report on the local market entitled ‘Fixing our broken housing market.’ The association recognised that the White Paper highlighted a need to continually review the current energy performance standards with regard to climate change targets and to domestic fuel poverty. It added that this should be extended to include the performance in flood risk areas of housing and the materials used in their construction.

‘The White Paper launches a consultation with a range of recommendations to increase numbers of homes being built in the UK. However, there are likely to be many conflicting views so I hope the government doesn’t use this as a way of kicking the problem into the long grass. However many houses are built we must ensure that all new housing is highly energy efficient in line with our climate change objectives. Just because there is a rush to build shouldn’t be an excuse to lower the quality of the thermal performance. And we certainly don’t want to have to come back and retrofit in 20 years because the houses we build today do not meet tomorrow’s requirements,” said Simon Storer, the chief executive of BRUFMA.
