Floor drain DN50 horizontal with siphon and cover with frame for tiling 132x132mm/112x112mm HL510N-3020

Roof drains – reliable drainage for terraces and balconies

This horizontal roof drain DN50, equipped with a siphon and a cover with a frame for flush mounting (132x132mm/112x112mm), is an optimal solution for draining water from terraces, balconies and other surfaces exposed to precipitation. Designed for easy installation and durability, it provides effective and aesthetic drainage.

Design and application

The drain is designed for horizontal outflow, which facilitates integration with existing infrastructure. The water siphon prevents the return of unpleasant odors from the sewer system, and the adjustable height of the cover (in the range of 10-80mm) allows for a perfect fit to the chosen cladding. The drain collar enables a tight connection with the waterproofing layer, using dedicated sealing kits from the HL83 series – crucial for ensuring long-term protection against leaks. A water flow rate of 0.55 l/s at a head of 20mm and 0.45 l/s at a head of 10mm guarantees effective drainage even during heavy rainfall. Thermal resistance up to 85°C allows for use in places exposed to higher temperatures.

Flexibility and compatibility

This drain stands out for its versatility thanks to the possibility of adaptation to different roof layer arrangements by using appropriate simple and collar extensions (HL340N, HL85N, HL85NC, HL85NH). This solution is appreciated by both installers and end customers looking for a flexible drainage system. The possibility of tight integration into the waterproofing layer is an additional advantage ensuring the safety and durability of the structure. It is worth remembering the compatibility with DN40/50 inlets.
