Roof inlet for renovation of downpipes DN110 with bituminous collar HL69H/1

Roof inlet renovation – quick installation and time saving

This renovation roof inlet, designed for downpipes with a diameter of DN110, is an ideal solution during roof renovations and modernizations. Its construction allows installation in the existing inlet without the need to dismantle the vertical drain – which significantly reduces working time and minimizes costs. This is particularly important during thermal modernization, where efficiency and minimizing interference with the existing building structure are crucial.

The inlet is characterized by a high flow rate of 7.80 l/s, ensuring effective drainage of water from the roof. Made of durable polypropylene (PP), it is resistant to weathering and corrosion, guaranteeing long-term reliability. A bitumen collar provides a tight connection with the roofing material.

Key features and benefits:

• Renovation installation: Eliminates the need to dismantle the existing recessed drain – saving time and costs.
• Wide sealing tolerance: A range of 100-108mm makes it easy to adapt to different diameters of downpipes.
• High flow rate: 7.80 l/s ensures effective water drainage even during heavy rainfall.
• Durable material: Polypropylene (PP) guarantees resistance to weather conditions and long service life.
• Tightness: Bitumen collar ensures a secure seal with the roofing material.
• Completeness: The set includes a debris screen (Laubfangkorb d 145mm) to prevent clogging by leaves and other debris.

This inlet is not only an element of the drainage installation, but above all a practical solution for professionals and building owners who appreciate convenience, speed of installation and durability. Thanks to it, roof renovation becomes less invasive and more efficient.
