Residents and campaign groups called for a ban on the use of combustible building materials
The Grenfell Tower was clad in aluminum panels and a combustible plastic core. It was also supported by a synthetic insulation that was classified as flammable.
But Hackitt stayed with BBC Radio Four on Thursday and insisted on their attitude, no open prohibition of all flammable materials in disguise, insisting that such a move would not solve the whole problem.
"The manual already says that you can only use materials with limited flammability or materials that have been fully tested," she said.
"It's clear that Grenfell and the other tests were done despite the current guidelines I say people would put up other materials, so I do not think a ban will work."
Activists, local residents and legislators voted for a total ban on facades and a review of building regulations.
Disguise on hundreds of skyscrapers Everywhere in England, which was tested after the fire, failed safety tests.
Legislators: "A betrayal and a whitewash"
Shahin Sadafi Chairman of the local election campaign group Grenfell United said the report "made the inhabitants disappointed and saddened."
"Concern that a fire like Grenfell could happen again keeps us awake at night," Sadafi told the BBC
"When we met Lady Judith Hackitt we asked her to ban flammable disguises saddened that she did not listen to us and did not listen to other experts, the Grenfell Towers disguise was considered to be limited flammable … it must be banned. "
In response to the criticism, Hackitt rejected allegations that a complete ban on disguise would solve all problems.  "If people feel that I have not gone far enough and this system needs to work in the future, then there must be more clarity or even the ban on some of the materials currently in use, I do not have a problem with it, "she said.
"I'll be disappointed if people think that the mere ban on disguising will solve this problem, it's a broken system, and disallowing disguise alone will not fix it."
The review follows one Judge-led investigation of the Grenfell fire starting on May 21st.
