Raymond Barlow, assistant head of planning and building standards of Glasgow City Council, told MSPs a search had revealed combustible cladding had been used on some private properties.
He said the local authority - which is the largest in Scotland - had only recently notified Scottish ministers about the matter and had not told either the Scottish Fire and Rescue Service or the owners of the buildings concerned.
“We’re simply saying we’re supplying the information to Scottish ministers and then we wish to see what they wish to do with the information before we take it further,” he told members of the Scottish Parliament’s Local Government and Communities Committee.
Mr Barlow refused to say how many buildings could have combustible cladding, saying only that he was “wary” about speaking about the extent to which high rises in the city are affected.
The exact number of people killed when fire swept through the Grenfell Tower building in London on June 14 is still not confirmed - although the Metropolitan Police say the death toll “may come down a little bit’’ from the current estimate of about 80.
Mr Barlow said an initial check on housing association flats in the city had not found any combustible cladding, telling the committee: “Our trawl and our research from then on was very much on private flatted developments, and that information we only managed to complete in the last couple of weeks, and I have passed it over to the ministers.”
Convener Bob Doris then asked him: “So, combustible cladding has been found in some private properties?”
The council official responded: “Yes, it’s just not public information yet.”
Mr Doris replied: “It’s now public information because you are telling us.”
