1) ONDUVILLA can be installed on all standard roof structures-wooden battens, wooden deck, steel battens or concrete slabs. Laying of purlins - Purlins have to be placed at 32cm distance, centre to centre. Since there is an overhang of 5cm at the eaves, the distance between the first and second purlin is 27cm, centre to centre. ROOF PITCH Roof> 17o (30%) Support: decking or purlins at 320mm centres Roof betwen 9o and 17o (15% and 30%) Support: decking or purlins at 160mm centres |

2) Installation principles Start installation at eave, in the opposite direction of the prevailing wind. Position the dark strip on top. Stagger the rows, by starting the second row with a half tile. Horizontal overlaps are one corrugation. Ensure proper waterproofing by aligning the overlapping guides. |
 |
3) Fixing ONDUVILLA is to be fixed at each overlap and corrugation with ONDUVILLA fasteners. Fix the tiles following the order described beside, betwen the 2 overlapping guides. Do not fix those corrugations that will be overlapped by the next tile or verge piece. |
 |
4) Standard Ridges Ensure that the maximum distance from the ridge point to the next purlin is 15cm. If necessary, add an extra purlin to maintain this distance. The ONDULAIR Slim can be fixed below the ridge piece to provide watertightness and additional ventilation. Overlap between ridge needs to be maintained at 15cm. |
