The UK Building Regulations state that buildings must be designed and constructed to limit the spread of fire. This may be internally or externally (across the façade or from one building to another).

To offer guidance on this subject the UK Government released a series of documents called Approved Document B (Fire Safety), which set out recommendations on how to limit the spread of fire in buildings.

The document covers most of what you need to know as a designer or contractor, although it’s important to note that it does not guarantee adequate fire prevention performance of a façade.

It is the responsibility of the designer to ensure that what is in the Approved Document B is relevant to their building and it is necessary to identify the requirement of any additional measures.

Metal façades are fire resistant but the finish of the metal does need to be compliant with requirements for surface spread of flame (Class O [National] or Class B [En] above 18m).

Polyester powders for coating aluminium generally do meet these requirements, but if you want to know more about specific finishes from our range please get in touch with us for further details.
