As the climate brings heavier and more frequent rainfalls, the demands on buildings’ ability to handle large volumes of rainwater are increasing. Our parapet systems with spouts provide a reliable and effective safety drainage solution for roofs – especially flat roofs – where water accumulation can cause serious damage to the building’s structure.
This product range is designed to direct excess water out through the building’s parapet, thereby preventing water accumulation and potential flooding. This makes parapet systems an essential part of a modern, well-functioning roof drainage system.
A spout through the parapet functions as a safety valve in situations where the roof drainage cannot keep up. By directing the water horizontally – directly out through the facade – it prevents stress on the roof membrane, insulation, and supporting structure.
Advantages of parapet systems with spouts:
Safety drainage during extreme rainfall
Direct discharge through the parapet
Prevention of damage to the roof and façade
Quick installation and high operational reliability
Option for visual inspection and maintenance
These outlets ensure a flexible and tight seal around the penetration. The EPDM overflow ring creates the necessary accumulation height, so the system is only activated in emergency situations. The top protects against debris and prevents accidental blockage.
Features:
Oval shape for easier installation in the parapet
EPDM ring ensures a flexible and watertight transition
Ideal for facades with limited space
This solution combines a fixed overflow height with an effective leaf grate that prevents leaves and debris from blocking the drain. It is an optimal choice for roofs with many nearby trees or buildings with high requirements for low-maintenance operation.
Features:
35 mm accumulation height integrated
Rectangular design suits modern architecture
Built-in leaf guard reduces maintenance
All components in the system are made from weather-resistant materials such as stainless steel and UV-resistant plastic. This ensures a long service life and minimal maintenance – even under harsh climate conditions. The outlets can be easily integrated into existing structures and adapted to different wall thicknesses and facade designs.
