Iplex rainwater downpipe is made of extruded uPVC, containing titanium dioxide as an ultra-white pigment and U.V. stabiliser.

It is available as a solvent weld joint system and can be used on light commercial buildings, houses, garages, carports, hay sheds, and wool sheds. It will collect rainwater from all New Zealand roofing materials for dispersal into storm water systems or drinking water storage, even in the most corrosive seaside atmospheres, or in thermal regions.
