The lightweight metal architectural cladding that is believed to have played a significant part in a deadly June 2017 fire in a London apartment tower is still being used on thousands of buildings around the world, but what can be done about it?

On June 14, 2017, a fire in fourth-floor apartment of London’s 24-story Grenfell Tower quickly spread upward. While the investigation is ongoing, it’s believed that the cladding — Reynobond PE, which sandwiches a polyethylene core between two sheets of aluminum — created a chimney effect that drew smoke, heat, and flames up the tower’s exterior, setting fire to additional apartments along the way.
