GLASGOW'S flagship Queen Elizabeth University Hospital has reportedly been clad in some of the same material as used in Grenfell Tower.

The new 14 storey superhospital uses Kingspan Kooltherm K15 Rainscreen Board, which last night was identified as the third product used in the covering wrapped round the London high rise, which was all but destroyed in a fire last month, killing around 80 people.

Channel 4 News discovered the new element in the Grenfell Tower cladding, and found in their own tests that the material caught fire "almost instantaneously".

UPDATE: NHS chiefs quell concerns over Grenfell Tower cladding at Queen Elizabeth University Hospital

The other two components in the cladding used on the London Tower block were Reynobond outer panels and Celotex RS5000 insulation.

The Celotex RS5000 has since been removed from sale for use on high rise buildings, but seemingly the Kingspan insulation has not been part of the government's investigations.

On the Kingspan website, the Govan hospital is used as a case study where the firm boasts how the use of their cladding helped to “fast-track the building control checking and approval process.”

After the fire at the Grenfell Tower, a spokesman for NHS Greater Glasgow and Clyde said: "We proactively started reviewing our facilities last week. No concerns have been identified."

The National has approached the health board for comment in light of the new information.

In a statement, a Kingspan spokesman told The National: "Kingspan recognises that the terrible tragedy at Grenfell Tower has raised understandable concerns about the implementation of building regulations, the adequacy of those regulations, the materials used in building construction and refurbishment, and how these impact one another.

"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.

"To the best of our knowledge, the vast majority of the insulation used for the façade refurbishment was PIR (polyisocyanurate) that had no connection with Kingspan. However, subsequent to the Grenfell tragedy we became aware that a very small quantity of Kingspan Kooltherm K15 (less than 5 per cent of the estimated total amount of insulation used on the Tower facade) was sourced by a third party distributer and supplied to contractors involved in the refurbishment.

"Whilst we are still seeking to establish the facts of what occurred, 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.

"Kingspan is very confident that properly installed and specified our products deliver safe, reliable and energy efficient insulation solutions.

"Given the ongoing investigations by relevant authorities into the Grenfell Tower fire it would be inappropriate to comment further at this time. "

Campaigner Sean Clerkin called on the government to test every major Scottish building using cladding to be tested at the Building Research Establishment: "As I have been saying over recent weeks to anyone who has been listening, all the major buildings have to be fire tested at the BRE. That includes our tower blocks”.
