  1. Why are they concentrating on aluminium cladding which does not burn. It is only plastic cladding and the wrong insulation that burns, surely???

  2. The discussion I had yesterday with a QS on the issue of fire safety and materials, was along the lines of ‘where does it say in the Regs that product x cannot be used’, and, if we change the specification so that certain products (that give off toxic smoke in a fire) aren’t used, where do we stop?

    I can well imagine the same was said at Grenfell, with its nominal Class 0 cladding, and its tested Celotex insulation.

    That kind of attitude is troubling, as ultimately it seems to me people like QS’s are the ones advising the clients and making the call, but in the process having little to no accountability for the outcome, as they aren’t the designers who have the responsibility if something goes wrong.

  3. Any kind of cladding needs to be considered. It is possible to have cladding with BS EN 13501-1 European Class A1 or A2 cores with SURFACE SPREAD OF FLAME ratings to facing materials lower than the European Class B and C allowed by the English and Welsh Building Regulations. Diagram 40 in Paragraph 12.6 may also allow the converse. Facing materials that achieve the European Class B and C, but have combustible cores of European Class D. In the case of Grenfell Tower the cladding material was certified as compliant with the Approved Document Part B Volume 2 for its surface, which ignores the fact that the core could be combustible. So watch our for laminated cladding products that combine finishes and facings with cores.
