Can I use Onduline bitumen sheets for cladding?
Onduline sheets are not classified to External S.AA fire rating as required in UK Building Regulations for some classes of structure. We do not advise they can be used for cladding due to the dangers associated with the spread.
It is recommended to exclude corrugated bitumen sheets that are classified E (reaction to fire) and Froof (resistance to fire) for vertical cladding applications – in case of fire, their shape would ease air flow circulation from bottom to top of the cladding and accelerates fire spreading.
