The risk of involvement of cladding in non-combustible construction has long been an issue culminating in the advent of Exterior Insulation and Finish Systems (EIFS) in the 1980s and 90s. The development of the CAN ULC S- 134 test method for use in non-combustible construction enabled representation of the typical scale of exterior fires and is generally indicative of the potential hazard arising from cladding in non-combustible construction.
