Extension for roof inlets with PE collar series HL62, HL64 HL65PE

Roof inlet extension – extension and insulation sealing

This extension element with a collar is designed for HL62 and HL64 roof inlets. It is used to effectively extend the inlet by the height of the thermal insulation, which is particularly important for roofs with a complex layer structure. It provides a tight connection with the next layer of waterproofing, minimizing the risk of leaks and ensuring long-term roof protection.

Construction and application

Made of polypropylene (PP), the extension has a height of 300 mm and a diameter of 125 mm. A bituminous collar with a diameter of 500 mm guarantees effective sealing of the connection with the roofing membrane. This product is used in flat roof drainage systems where it is crucial to take into account the height of the thermal insulation and ensure reliable water drainage. It allows for flexible adaptation of the installation to specific design conditions and ensures compatibility with various types of waterproofing.

Advantages and benefits

• Tightness: The bituminous collar provides reliable sealing, protecting against water leaks.
• Compatibility: Designed for the popular HL62 and HL64 roof inlet series, making installation and replacement easier.
• Adjustment to insulation: Allows precise adjustment of the inlet height to the insulation layer, ensuring optimal drainage system performance.
• Durability: Made of high-quality polypropylene (PP), resistant to weather conditions and mechanical damage.
• Solution for complex roofs: Enables proper drainage of flat roofs with complex layer arrangements, where standard solutions may be insufficient.
• Easy installation: The element's design facilitates quick and efficient installation by professionals.

Additional accessories, such as gaskets (HL01020D, HL01058D), drainage grates (HL170, HL175) and leaf baskets (HL062.1E) allow for a complete drainage system configuration. Supporting rings (HL062B.3E) and drainage rings (HL160) further strengthen the structure and ensure the stability of the entire system.
