An investigation by the management of the Torch after its 2015 fire found that most of the damage was to the cladding, exterior panelling used for decoration or insulation.

In the UK, police have said they believe the system of insulation and cladding panels on London's Grenfell Tower may have contributed to the rapid spread of a fire there in June in which some 80 people died.

And they were able to do it. That was their design, using that same computer modeling system and only five or six really different kinds of parts, a couple of struts, like this, some exterior cladding material and a very simple framing system that was all manufactured off site and delivered by truck.
