Officials investigating London's fatal Grenfell Tower fire have released new details on the safety of the building’s materials.

Further Testing

In a letter to residents published March 15, the Ministry of Housing said that a door that was taken from the building (from a portion that was not ravaged by fire) had undergone fire safety tests. The tests revealed that the door, which should have been able to withstand flames for 30 minutes, could only withstand fire for 15 minutes.

Officials investigating the fatal Grenfell Tower fire have released new details on the safety of the building’s materials.

The fire-safety tests issued on the door are in addition to multiple tests on cladding and aluminum composite material systems that were done immediately following the June fire.

Six ACM systems were analyzed with a variety of insulations in accordance with the British Standard 8414.

“This involves building a 9-meter-tall demonstration wall with a complete cladding system­—including panels and insulation­—fixed to it, and then subjecting it to a fire that replicates a severe fire in a flat breaking out of a window and whether it then spread up the outside wall,” the Department for Communities and Local Government said in a statement at that time.

The systems incorporated the three common types of aluminum composite material panels, with core filler materials of unmodified polyethylene, fire-retardant polyethylene and non-combustible mineral. The insulation materials used in the testing were rigid polyisocyanurate foam or non-combustible mineral wool.

All 82 systems tested in that process failed.

As for the door, housing secretary Sajid Javid said that further testing on the door was ordered, and because officials aren’t sure if the exact same door was installed elsewhere in the tower, no change to fire safety advice is being issued to the public. Javid went on to say that there is “no evidence that this is a systemic issue.”

Javid went on to say that there is “no evidence that this is a systemic issue.”

Other officials disagree, however.

“If this isn’t systemic, what assessment has been made of how many buildings are potentially affected by this?” asked shadow housing minister Tony Lloyd. “How many individual flats? How many people who have fire doors that simply don’t do the job?”

This notice comes just weeks after housing ministry deputy divisional director Offer Stern-Weiner issued a memo to officials across England and Wales instructing them to consult with fire services as soon as possible when designing new buildings.

Stern-Weiner issued the instruction based off Dame Judith Hackitt’s preliminary report on the fire, in which she called for a complete overhaul of the construction industry but stopped short of prohibiting the use of specific products.

Hackitt’s final report is still slated to be issued in the coming weeks.
