Being a light, versatile and flexible material fixed to the roof structure, Onduline is less likely to hurt in case of earthquakes ;
Onduline is widely used in seismic regions like Central Asia and also Japan;
Yarsley Research Centre (UK) proved Onduline suitable in hurricane and earthquake conditions.
