Due to the flangeless design, alwitra® water spouts are particularly suitable for difficult and/or confined installation conditions.
- They are made of rigid PVC and, depending on the version, are equipped either with a welding flange for EVALON®® waterproofing membranes or with a factory-fitted flashing collar made of EVALON®®.
- Along with the alwitra® water spouts for pipes with various diameters, rectangular versions are also available
Water Spouts
As emergency overflows, alwitra® water spouts are part of the alwitra® roof and emergency drainage system for non-used or extensive green roof areas covered with EVALON® waterproofing membranes. They can be installed horizontally through the parapet.
Advantages
- Available in various standard DN diameters
- They feature particularly high discharge rates at low ponding heights.
Applications
- Suitable for horizontal installation, e.g. through a parapet
