FAQ

Onduline Material is classed under the Combustible materials category. According to European norms, classifications are as follows :
Reaction to fire EN13501-1 = Class E  (Class A = incombustible, Class F = Easily combustible, Class E = combustible to a normal degree)
Resistance to external fire EN13501-5 = F-Roof (Class F = ‘Non determined’ meaning it doesn’t pass the European burning tests).
