Fire expert: Grenfell Tower tragedy 'entirely predictable'

Comment

As a Facade consultant working with these materials for many years I fully understand the requirements of both the Building regulations in respect of suitable material selection and fire protection. The key is the fire protection, of which should have encapsulated the apartments individually. Using vertical and horizontal fire breaks installed, in the correct manner should have mitigated the fire, giving residents time to escape and fire fighter time to control the situation The choice of ACM is critical, as many have little or no fire protection other than surface spread of flame, of which at 1000 deg c the aluminium melts and exposes a polyethylene core of which propagates fire. ACM with fire rating are available but not cheap. Now the insulant used comes into question, likely it wasn't a mineral wool of which would have added nothing to the fire, more likely was used is the specified Celotex FR5000 product or a substitute of which needs to be investigated.
