Fire Resistance of Exterior Cladding Materials

 

The Grenfell Tower fire that occurred in London on June 14, 2017 is the most recent tragic example of a safety issue that has been plaguing the building industry for some time—specifically, the use of combustible materials with a high propensity for flame spread as part of a building’s exterior wall system. Accounts of this event report at least eighty deaths attributed to the fire, with another seventy injured.

Early reports suggest that the fire began in a fourth-floor apartment and that the point of origin may have been a fridge-freezer. The building had recently been reclad with aluminum composite panels, which are reported to be the main contributor of fuel for the fire. The event triggered an interest is checking other similarly clad buildings in Great Britain and elsewhere.
