What kind of fixing, screw or nail can I use?
It is important to use Onduline fasteners as they are specifically designed, developed and manufactured to suit the roofing application requirements with Onduline sheets and Onduvilla tiles. We recommend Onduline screws or nails to ensure best waterproofing, best aesthetics & wind resistance. Please consult Onduline Fixing Guide or commercial documentation. Onduline Warranty is applicable when Onduline has been installed in full respect of Onduline's installation instructions and if the system is installed with Onduline accessories and fasteners.
