In a bizarre report from thousands of miles away in Australia, BBC UK tell us tonight how the state of Victoria acted quickly after the Grenfell disaster and began to remove flammable cladding.
They clearly missed a clue in their own August 2021 report into a Glasgow tower block, where despite it having flammable panels, the fire did not spread up the building, was contained on one floor and no one was hurt.
Surely that’s intriguing and suggestive of something that might be learned?
I’ve explained it many times before. Here it is again:
The Chimney Effect
As I understand it, it is not so much the flammability of the material used as the construction of the external cladding to deny the spread of fire via a chimney effect.
Reader Gordon Darge wrote for us in January 2020:
As a chartered architect in Scotland for 40 years I can confirm that the Building Regulations Technical Standards Scotland have for two decades required cavity fire barriers
Every building must be designed and constructed in such a way that in the event of an outbreak of fire within the building, the spread of fire and smoke within cavities in its structure and fabric is inhibited.
This includes for example, around the head, jambs and sill of an external door or window opening, at all floor levels and building corners etc. to prevent the spread of fire in building cavities. This would have prevented the spread of the fire at Grenfell Tower.
This is difficult and expensive to achieve and I can only guess that in England they did not follow the Scottish model because Westminster and the Tories were led by the vested interests of big business, property developers and large construction firms.
