Parapet Outlet 160x40

For drainage from flat roofs with roofing felt or roof foil in a low insulation layer, where the roof drain pipe is to be led through the parapet/end wall. If the standard roof outletpipe is too short to pass through the building's facade, the pipe can be extended with a welded joint made by JUAL.

Efficient and flexible drainage through the parapet

Drainage from flat roofs requires reliable and customized solutions—especially when the construction presents unique challenges for installation and penetrations. JUAL’s Parapet Outlet 160x40 has been specifically developed for this type of roof structure, where horizontal drainage through the parapet or end wall is desired.

With a focus on functionality, watertightness, and flexibility, this drain is an ideal choice for modern and technically demanding roofing projects.

The solution can be used both as a primary drainage outlet and as part of an safety drainage system, depending on the building’s structure and load requirements.

Especially suited for roofs with low insulation height

The Parapet Outlet 160x40 is designed for flat roofs with bitumen or synthetic roofing membranes, where the insulation height is low. This makes it particularly relevant for buildings with minimal build-up height, where traditional roof drains may be too deep or impractical for proper water routing.

The outlet is constructed to integrate seamlessly with the roofing membrane while allowing for horizontal water discharge through the building’s exterior wall. This enables hidden or facade-controlled outlets—an advantage both aesthetically and technically in many modern buildings.

Option for welded pipe extension

A common challenge with this type of installation is that the standard drain pipe may be too short to extend all the way through the building facade.

At JUAL, we offer a practical solution: The pipe can be extended with a welded joint, performed at our own factory.

This factory-mounted extension ensures high watertightness and long durability, saving the installer time and ensuring a correct installation without extra work on-site.

Technical construction and features

The Parapet Outlet 160x40 is manufactured from materials resistant to moisture, UV radiation, and temperature fluctuations. This makes it well-suited for the Danish climate, where changing weather conditions place stress on roof structures.
