PVC downpipes for the connection of bituminous roofing with rainwater drains.
Resistant to degradation caused by the sun, ozone and other atmospheric or chemical agents normally present. They have a high flexibility even at low temperatures. The mechanical characteristics remain unchanged over time. They are compatible with prefabricated bituminous membranes such as APP, SBS, APAO and coated bitumen. Sandwich laying is recommended. For better gluing, the nozzle can be previously spread with a light coat of primer.
