Roof inlets – reliable drainage for terraces and slabs

This adjustable roof inlet DN50/75 with a bituminous collar is an optimal solution for draining water from terraces, balconies and slabs. Designed for easy installation and tightness, it provides effective protection against leaks and structural damage. Thanks to the adjustable outflow angle, you can adapt it to the specifics of the installation.

Tightness and flexible installation

A key element of this inlet is the bituminous collar with a diameter of 420 mm, which allows for a tight connection with the bituminous waterproofing layer. This guarantees safety and long-term operation. Additionally, the adjustable height of the top in the range of 12-70mm allows for a perfect fit to the layers of the slab. The siphon prevents the return of unpleasant odors.

Construction and application

The inlet has a DN50/75 outlet pipe with an adjustable outflow angle in the range of 90 degrees, which facilitates integration with the existing water drainage system. Made of high-quality materials, including a stainless steel grate (115x115mm) and a mounting frame (123x123mm), it is characterized by durability and corrosion resistance. A flow rate of 0.5 l/s ensures efficient water drainage even during heavy rainfall. Thermal resistance up to 85°C allows it to be used in various environmental conditions.

• Versatility: The possibility of combining with straight and collar extensions (HL340N, HL85N, HL85NC, HL85NH) allows you to adapt the drainage to specific project needs.
• Optional accessories: The HL82 heating set can be used to prevent water from freezing in winter.
• Durability: Stainless steel construction guarantees corrosion resistance and long-term use.
• Easy installation: The bituminous collar facilitates a tight connection with bituminous waterproofing.
• Adjustment: Adjustable outflow angle and top height provide flexibility during installation.
• Hygiene: The siphon eliminates unpleasant odors from the sewage system.
