Extension for roof inlets with PP collar series HL62, HL64 HL65F

Roof drain extension – tightness and flexibility in drainage systems

This extension piece with a collar, designed for HL62 and HL64 roof drain series, is a key solution for the implementation of flat roofs with a complex layer structure. Its main task is to extend the height of the drain to allow proper connection with the thermal and waterproofing layer. This ensures complete tightness and reliable operation of the entire drainage system.

The extension allows for flexible adjustment of the drain height to specific project requirements, which is particularly important in the case of complex roof structures. It also enables easy and secure connection with various types of waterproofing, minimizing the risk of leaks and providing long-term building protection.

Construction and application

Made of durable polypropylene (PP), the extension is characterized by high resistance to weather conditions and mechanical damage. The sealing collar ensures a tight fit to the waterproofing layer, and the clamping ring further stabilizes the connection. The total height of the extension is 345 mm, allowing it to be adapted to most standard insulation systems.

The application of the extension is wide – it is ideal for both newly built and renovated roofs. This is particularly important during renovations, where non-standard conditions and drainage requirements often occur. Thanks to it, you can effectively solve problems related to water drainage from the roof surface, ensuring its durability and safety.
