LORO-X Light flat roof drains
One drain made of stainless steel – available in two flange versions to match the type of waterproofing on your roof: with stainless steel adhesive flange in DN 70, 80 and 100 or with composite sheet flange in DN 70.
Which waterproofing – which flange?
| Your waterproofing | Matching version | Nominal sizes |
|---|---|---|
| Liquid plastic | Stainless steel adhesive flange | DN 70, 80, 100 |
| Bituminous membrane | Stainless steel adhesive flange with pre-treatment | DN 70, 80, 100 |
| Plastic waterproofing membrane | Composite sheet flange (membrane can be welded on directly) | DN 70 |
Tapping takes you straight to the respective version. The waterproofing is carried out in each case in accordance with the processing specifications of the waterproofing manufacturer.
Common to both versions
For small roof areas, balconies and carports
LORO-X Light drains are optimized for space-saving installation in small roof areas, balconies, carports and garages. They meet the minimum discharge requirements of DIN 1986-100 for gravity flow and therefore enable simple design according to the standard.
Stainless steel hood
The stainless steel hood is simply clamped into the base body of the drain. Thanks to its specially developed shape, it automatically locks itself in the drain, ensuring it remains securely fixed during physical stress or strong winds, yet can be removed without tools for maintenance purposes.
Advantages of both versions
- Optimized for small areas
- Base body and hood made of stainless steel
- Fast, secure and tool-free sealing
- Simple dimensioning with the minimum discharge according to the standard
- Composite sheet and stainless steel flange do not break under load
- Drill holes for permanent fastening in the roof structure
Versatile – with LORO-X plug-in sleeve in the base body
- As main drainage with plug-in hood
- As emergency drainage with sealing element and retention element
- As renovation drain or extension element in existing drains with lip seal
- As one-piece and two-piece drain for cold roofs and warm roofs – the thermal insulation of the roof structure applies equally to both flange versions
- As backflow-proof pipe penetration with sealing element
LORO-X Light
Version 1: Stainless steel adhesive flange
For liquid plastics – with pre-treatment also for bituminous membranes
With the model featuring a stainless steel adhesive flange, the sealing of the stainless steel surface is carried out with liquid plastic in accordance with the manufacturer's specifications of the selected supplier. With appropriate pre-treatment, the stainless steel adhesive flange is also suitable for bituminous membranes.
With this universal flange, the model is particularly suitable as a stock item for specialist dealers and roofers with their own storage space who do not want to commit to a single type of waterproofing. This model is also ideally suited for renovations, as sealing with liquid plastic is possible in virtually all encountered situations.
Available in DN 70, DN 80 and DN 100.
- Sealing with liquid plastic on the stainless steel surface
- With pre-treatment also suitable for bituminous membranes
- Universal stock item for specialist dealers and roofers

Version 2: Composite sheet flange
For plastic waterproofing membranes
For easy sealing with plastic waterproofing membranes, LORO-X Light drains are available with a factory-installed composite sheet flange. The generous dimensions of 300 x 300 mm exceed the minimum overlap of 30 mm, and sealing can be carried out easily with a hot air gun – entirely without additional tools. The drain pipe is connected pressure-tight and backflow-proof with LORO-X steel drain pipes; if required, connecting pieces or transition sealing elements are also available.
Optionally, a factory pre-punched connection sleeve can be ordered for each composite sheet type in order to connect the composite sheet flange professionally to the surface membrane. The time-consuming cutting on the construction site is eliminated, and the connection details always look perfectly cut to the building owners.
Available in DN 70 – factory-prepared to match the respective membrane brand (including Bauder, Alwitra, Sika, Rhepanol, Wolfin, Sarnafil, FDT).
