ONDUVILLA tiles are not classified to External S.AA fire rating as required in UK Building Regulations for some classes of structure.
The material used to make ONDUVILLA tiles is the same as ONDULINE roof sheets.
The Onduline material is classed under the Combustible materials category: Reaction to fire EN13501-1 = Class E
According to European norms, classifications are as follows:
- Class A = incombustible
- Class F = Easily combustible
- Class E = combustible to a normal degree
ONDUVILLA Tiles should only be used for non-habitable buildings.
(A non-habitable building is a space that is not suitable for people to live in or sleep in)
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 and tiles 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.
