Extension for roof inlets with PVC collar series HL62, HL64 HL65P

Roof drain extension – tight connection of insulation and waterproofing

This extension element, designed for HL62 and HL64 roof drains, is a key solution for the implementation of flat roofs with an extended layer structure. Its main task is to extend the drain by the height of the thermal insulation, while ensuring a tight connection with the next layer of waterproofing. This is an ideal solution for installers who need to adapt the drainage system to specific project requirements.

The HL65P extension is made of durable polypropylene and equipped with a PVC collar, which guarantees durability and resistance to weather conditions. This ensures reliable operation for a long time. The total height of the extension is 350 mm, which allows for flexible adjustment to different insulation thicknesses.

• Compatibility: designed for HL62 and HL64 roof drains.
• Material: polypropylene – a lightweight yet durable material resistant to corrosion.
• PVC collar: ensures a tight and durable connection with the PVC waterproofing membrane.
• Height: 350 mm – allows adjustment to different thicknesses of thermal insulation.
• Application: ideal for flat roofs with a complex layered structure, where precise fitting of drainage elements is required.

The installation of the extension is simple and intuitive, which translates into saving time and labor costs. This element allows you to create a complete drainage system that effectively drains water from the roof surface, protecting the building structure from moisture and damage. Thanks to this, the investor can count on long-term protection of their property.

Additionally, it is worth mentioning the possibility of using this extension in combination with other elements of the Hutterer & Lechner drainage system, such as drainage grates or extensions, which allows you to create a comprehensive solution tailored to the individual needs of each project.
