How can we fix ONDULINE HR® on wooden and steel construction roofs?
ONDULINE HR® sheets can be fixed to wooden roofs by using at least 20 mono block nails (there should be at least 20 mono block nails visible on the roof after the sheet is applied) and can be fixed to steel construction roofs by using at least 11 mono block nails (there should be at least 11 mono block nails visible on the roof after the sheet is applied).
Do the nail holes penetrate water?
Due to the fact that it is fixed by specially developed Plastic Head Mono Block Nails by hammering them atop the conduits, excellent water insulation is achieved. The Mono Block Nail heads are not affected by the climatic conditions and sun rays. Original mono block nails should always be preferred during application.
