Grenfell Tower cladding that may have led to fire was chosen to improve appearance of Kensington....

7. Most 60s-70s high rise buildings

looked like they'd fit into Nazi Disneyland. The panels did improve the appearance of the building and they did offer additional insulation. It looks like the exterior was fire resistant, that's what peeled off and fell on first responders and people trying to flee the building. I think the Achilles heel was likely those decorative ground to roof triangular bump outs. It looked like they acted like chimneys conducting the fire up and catching fire, themselves, on the inside where the insulating material was.

It's a pity they didn't retrofit sprinklers rather than spend money on esthetic improvements.
