The council today confirmed that as well as an "extremely robust" review of fire safety at its own tower blocks, it is also carrying out urgent checks in private sector blocks, which can include student accommodation blocks and other high rises.
"The estimate by Camden Council itself is they need at least 1,000 fire doors because they were missing from those five blocks".
The company manufactures three main types of Reynobond panel: one with a polyethylene (PE) core, one with a fire retardant core and another with a non-combustible core, according to its website.
Fire officials are checking the safety of thousands of buildings nationwide amid fears by residents that what happened at Grenfell could happen to them.
Building safety experts have warned that government tests on tower block cladding in the wake of the Grenfell Tower disaster lack transparency and are too simplistic to be used to condemn blocks as unsafe.
The London Borough of Hounslow, where the Clements Court tower failed the DCLG test, panels are being "swiftly" removed, but the council stressed: "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".
British investigators have said the Grenfell blaze began when a fridge in a fourth-floor apartment caught fire. Grenfell Tower is more than 60 meters tall. "However, it said it did not participate in refurbishing the building or in the original design".
Members of the emergency services work inside burnt out remains of the Grenfell apartment tower in North Kensington, London.
Speaking in response to a Commons statement from Mr Javid, Ms Dent Coad said: "I've heard this morning, shockingly, that people who have concerns about their immigration status or lack of documentation are still not coming forward and sleeping rough".
Grenfell Tower and numerous buildings tested are all part of government-run, low-cost, public housing developments.
"The fact that all samples so far have failed the test underlines the value of the testing programme and the vital importance of submitting samples urgently", he said, adding the lab can test 100 samples a day and runs around the clock. The system is a cementitious material with mineral wool insulation.
Cladding, both from Arconic and others, has been widely used on low-income housing in the United Kingdom in recent years, in an apparent attempt to beautify older structures as London and other cities become more gentrified. But under the regulatory system in force in Britain, builders and property owners faced no such restrictions and may have wrapped hundreds of buildings in the potentially risky cladding.
