There are no lives at risk from a Grenfell-like towering inferno in Scotland due to cavity fire barriers and higher building standards but tell that to the Herald

In the Herald today:

‘Lives at risk’ as ministers spend just 11% of £97m Scots safety fund

Ministers have come under fire as repairs on ‘dangerous’ cladding have reached a “scandalous” standstill with just 11% of a special safety fund spent so far – eight years after the Grenfell tragedy.

Up to 1500 tower blocks across Scotland may need repairs, but as of June two are being made safe while funds committed have gone unspent.

It’s not clear from the report just who suggesting lives are at risk or that ministers are under fire (sic), but my money’s on Scottish Labour.

It is astonishing, if true, that only 2 out of 1 500 needing it have been made safe but here’s another explanation that has the benefit of facts behind it – Scottish tower block do not need their cladding replaced.

Here’s the story again:

Thanks to Iain AF Fleming @LegalWeasel for alerting me to this.

In June 1999, a fire spread up external cladding in the above block of flats in Irvine. There was one death.

Scottish media often use this case to suggest that towering infernos of the kind we saw in Grenfell London in 2017 can happen here. With 72 deaths and the complete burning of the building, the links to the Irvine case are a bit stretched, even for our media.

In Scotland, action followed quickly:

The Building (Scotland) Regulations 2004 require that buildings be designed and constructed to inhibit the spread of fire and smoke within cavities in the event of a fire. This is achieved by installing cavity barriers around the edges of cavities. 

Cavity barriers are constructions that seal cavities against fire and smoke, or limit their movement. They should be installed in the following locations:

Around the head, jambs, and sill of external door or window openings

Between a cavity and any other cavity

Between a roof space and any other roof space  

Cavity barriers should be fixed so that their performance is not affected by: Building movement, Failure of fixings, and Failure of any material or element of structure which it abuts. https://www.gov.scot/publications/building-standards-technical-handbook-2020-domestic/2-fire/2-4-cavities/

There have now been four fires in tower blocks in Scotland since then – Glasgow Knightswood in 2021, Glasgow Shawlands in 2022, Breadalbane Street Edinburgh in early 2024 and Cambuslang Glasgow in August 2024. All four fires were contained on one floor and there were no deaths.

In March 2021:

Christopher Mort, technical officer for fire, at cavity barrier manufacturer Siderise, was asked to inspect those that remained on the tower in July 2018, a year after the fire.

He said he found examples of areas where cavity barriers should have been with no holes drilled for fixing, leading him to conclude they had “not been installed at all” or fixed to the wall with silicone instead of a bracket.

He also found gaps of up to 140mm, well in excess of the 25mm which the barriers were designed to close, meaning they would have been unable to prevent the spread of smoke and flame in the cavity.

Vertical barriers were also installed incorrectly, with the bracket meant to hold them piercing the barrier and gaps left where there should not have been any, which would have allowed “fire, flame and smoke to travel behind the cladding”.

Asked how serious these errors were, he said: “It was some of the worst I have ever seen.”

He added: “There’s no grey area when it comes to inspection – it’s either right or wrong… If it’s significantly wrong like these barriers were, they have to be removed and replaced with new material.”

“Would it be fair to say these were fundamental errors which no reasonable installer should have been making?” asked Kate Grange QC, counsel to the inquiry.

“Correct,” he replied. https://www.insidehousing.co.uk/news/fire-barrier-installation-on-grenfell-some-of-the-worst-ive-seen-says-supplier-69928

The Grenfell inquiry has cast the blame quite widely. Doesn’t the above suggest the contractor is entirely to blame?

A Tory donor’s private equity firm was a major investor in the construction company accused of saving £5,000 by fitting cheaper and more flammable cladding to Grenfell Tower.

Mayfair-based Coller Capital owned a fifth of Rydon Construction via a partnership based offshore in Jersey when the building firm started work on the £10million refurbishment at Grenfell Tower in 2014. https://www.dailyrecord.co.uk/news/uk-world-news/tory-donors-firm-major-investor-10637120

In July 2020:

The contracts manager for Rydon during the Grenfell Tower refurbishment described residents who raised complaints about fire safety and cladding as “vocal and aggressive” at the inquiry today. https://www.insidehousing.co.uk/news/rydon-manager-brands-grenfell-residents-who-complained-about-fire-safety-aggressive-67256

Finally, from statistics around the time of Grenfell

In Scotland 2015/16, 9 827 safety audits were carried out. England has 10 times the population and so, all things being equal, might have been expected to have seen 98 270 fire safety audits. However, in 2017/18, England saw only 49 423 fire safety audits, just over half the number. Fire safety audits in Scotland were thus almost twice as common, per head of population, in Scotland as in England.

Why? Cost-cutting Tory local authorities? Cost-cutting Tory central government? https://www.gov.scot/publications/building-standards-technical-handbook-2019-domestic/2-fire/2-4-cavities

  1. Westminster has ( belatedly ) copied the Scottish Government’s approach to various social issues , the latest being the reduction in the alcohol limit for car drivers . This is to be applauded .

    Have they also adopted the Scottish ”cavity barriers ” to prevent the ‘chimney effect’ which was so devastating at Grenfell Towers ?

    Whether they have or not Scotland will not receive any praise for being years ahead of the lamentable fire regs which have been responsible for too many deaths south of the border .

  2. After June 11 1999 in Dundee Scotland changed the legislation on insulation. North Ayrshire Council removed the cladding and the UPVC Window frames. Not one person has died from a fire spreading to another floor in Scotland since then.

  3. I found this from Nicholson Nairn Architects very illuminating…
