It might be worth noting today that a German apartment building in Wuppertal (northern Germany) has temporarily kicked out around 70 of it's tenets because of the same matting-problem as in the London fire episode.
Eleven story building....built in the 1960s....had a renovation deal and the same type material was used.
Period of time until the material is removed? Unknown.
Odds of dozens of such buildings in Germany being found with the same material problem as in the London fire? I would imagine every single apartment building which had renovation in the past ten years will be evaluated. There could be dozens like this.
