Gravity roof inlet DN125 vertical with leaf basket and bituminous collar for welding with heat-fusible or cold-bonded roofing, inlet body thermally insulated HL62H/2

Effective flat roof drainage – gravity drain DN125

This vertical roof inlet with a diameter of DN125 is a reliable solution for gravity drainage of flat roofs. Equipped with a leaf basket and a bitumen collar for welding with heat-welded or cold-bonded membranes, it provides effective protection against clogging and leaks. The inlet design is also thermally insulated, minimizing the risk of thermal bridges.

Universality and installation flexibility

This inlet is distinguished by its high adaptability to various roof layer systems – from traditional to inverted, ventilated and green roofs. Thanks to the possibility of using additional elements, such as supporting or drainage rings (HL062B.3E, HL160, HL161), it can be perfectly adapted to the specifics of a particular project. A tight connection with the waterproofing layers guarantees long-lasting and trouble-free operation.

Efficiency and reliability

The inlet is characterized by a high flow rate – as much as 14.00 l/s, which translates into effective water drainage even during heavy rainfall. The possibility of connecting to HDPE pipes using a DN125 socket connection or the manufacturer's compensating socket ensures easy and durable installation. It is worth noting that the flow rate is higher than in many competing solutions available on the market.

Application and benefits:

• Wide range of applications: ideal for flat roofs of various structures (traditional, inverted, ventilated, green).
• Effective protection: bitumen collar ensures a tight connection with the waterproofing layers.
• High efficiency: flow rate of 14.00 l/s guarantees rapid drainage of rainwater.
• Easy installation: possibility of connecting to HDPE pipes using a socket or compensating socket connection.
• Durability and reliability: thermally insulated body and solid construction ensure long-term operation.
• Minimization of contaminants: leaf basket prevents dirt and debris from accumulating in the drainage system.
• Flexibility: possibility of expanding the system with additional elements (supporting/draining rings) adapting it to specific project needs.
