Fachmann extension elements

Fachmann extension elements help to arrange drainage from flat (including insulated) roofs. They are made of high-quality polymers, are resistant to ultraviolet radiation, as well as atmospheric influences.

Extension elements can be used as a base for a roof funnel, which results in a two-level drain funnel.

They can be equipped with a corrosion-resistant metal pressure flange. There is also a cuff that prevents rainwater from penetrating into the insulation layers at the junction with the funnel.

The kit may include a funnel base, a 2-in-1 leaf catcher, a sealed cuff, a metal flange and a plug cover.
