ONDULINE VALLEY
To collect rainwater flowing into the valley area
ONDULINE VALLEY
The Valley is used to collect rainwater flowing into the valley area. It is made of bitumen material, reinforced with cellulose fibers and thermo-setting resin. The composite is colored with inorganic pigments. Material used and colour range offer a perfect match for ONDULINE Roofing systems. The product is universal and can also be used with other roofing materials.
Position the valley, and fix it with flat-head standard nails.
Once the valley is covered with the roofing elements, fix the sheets/tiles on top of their corrugations, into the supporting batten. When supporting batten is not available, a possible alternative is to fix the sheets/tiles diagonally through the 2nd corrugation of the valley.
A universal ventilated filler can be added, to prevent birds or other animals to enter into the roof space.
The waterproofing of surrounding details, especially the connection to ridge, should be secured by using ONDUBAND or a similar Bitumen tape.
For more details, refer the fixing guide.
