What is the difference between Coroline and Onduline?
The main difference between the two roofing sheets is their thickness, weight, and price. Whilst Coroline sheets are 2.6mm thick, Onduline is slightly thicker at 3mm. Onduline sheets are therefore more rigid and capable of withstanding more impact.

Working on roofs can be a hazardous operation. Personnel should walk on roofs only if this is absolutely necessary, and should use planks or ladders laid flat and supported by the roof purlins, in order to carry out maintenance and related work.
