Application of PVC parapet funnel on the flat roof of a private house.

  • The funnel is designed for installation on the parapet, and serves as an emergency or main drainage channel. The funnel is welded by hot air devices to the main waterproofing carpet and adjacent to the PVC membrane parapet. Thus, an absolutely hermetic connection of the funnel and the PVC membrane is obtained.
