Also worth adding that all materials used would need to meet the current requirements for fire safety (or any other aspect of the construction), this would either be done through industry approvals as laid out in the specifications for any project or by the contractor submitting full data on an alternative to the Main Contractor and engineer/consultant for the project. Multiple people/companies would have signed off on all the materials being used as being up to the required standard for whatever purpose that material has.

Obviously at this early stage the cladding is coming under close scrutiny not as the source of the fire but certainly one of the factors that caused its very rapid surge up the building. I haven't read anything about it specifically but I am sure it carries some sort of industry approval with regards to the materials used in it that meets or exceeds the current building codes. I did see that the core of this cladding used material that is no longer allowed in cladding here in the US as prescribed by the current fire laws over here but it is still allowed in the UK and probably other European countries. Aside from other issues with these types of buildings, I am guessing that one of the eventual outcomes of this tragedy is a change to the fire codes with regards to the materials allowed in cladding, but as is often the case the stable door is already open!!
