Following the fatal Grenfell Tower fire , which has left at least 79 people dead, the council sent a sample from Clements Court tower in Cranford, for testing.
The 13-storey council owned tower block was re-clad in 2008, and is the only cladded high-rise in the borough that has used Aluminium Composite Materials, according to the council.
"We have, therefore, decided that we will take steps to remove the outer cladding"
In a statement, Leader of Hounslow Council, councillor Steve Curran said: "We were informed late last night [June 22] by the DCLG [Department for Communities and Local Government] that the sample of the outer ‘Aluminium Composite Material’ [ACM] cladding used on Clements Court tower has failed the Building Research Establishment [BRE] combustion test.
"The outer shell cladding is made up of two thin aluminium sheets with polyethylene filler in between them.
"However, the insulation material behind this outer cladding is a ‘rockwool’ material which is a non-combustible product, unlike the case of the Grenfell Tower, where the insulation was a combustible type."
"The system at Clements Court also differs from that at Grenfell Tower in so far as there was no interference with the interior of the building as part of the installation.
"We have, therefore, decided that we will take steps to remove the outer cladding from the building as soon as is practical.
"We are currently looking into how best and swiftly this can be done."
The council has said it has written to residents at the tower block, informing them of the procedure, and outlining what actions will be taken.
All tenants have also been invited to a meeting with the Director of Housing at 10am on Saturday (June 24), at the Alf Chandler Centre in Hounslow.
The council has also laid out other actions it is taking, including working with London Fire Brigade to carry out home safety tests in every flat in the tower block, starting from Friday (June 23), and running into the weekend.
Another Fire Risk Assessment will be carried out on Monday (June 26), fire watch patrols will start on Saturday (June 24), and all access to the block will be kept clear.
Councillor Curran added: "Our upmost priority is and remains the safety and welfare of our tenants at Clements Court and we will continue to respond swiftly to the recommendations from Government and the London Fire Brigade."
Eleven other buildings in the UK, including in north London, Plymouth and Manchester, have been found to have the same combustible cladding that was used on the exterior of Grenfell Tower.
The blaze was started by a faulty fridge , according to Detective Superintendent Fiona McCormack, who also said, on Friday (June 23), that the insulation and cladding tiles on the block have failed safety tests.
