The Rubberseal Kisner KADS Parapet Drain With Butylene Fleece Flange is designed to provide efficient and reliable horizontal drainage through parapet walls and upstands on flat roofing systems. Engineered for through-wall water discharge, it offers a dependable solution for managing rainwater at roof perimeters while maintaining a secure, watertight finish.
Available in 3” (62–75mm) and 4” (90–110mm) outlet sizes, this parapet drain connects easily to standard drainage pipework. Each unit features a precision-moulded integrated rubber gasket, creating a tight, leak-free seal to the existing pipe and helping to prevent water ingress or backflow under pressure.
Manufactured from high-quality polypropylene (PP), the drain body is built for long-term performance in demanding flat roof environments. The robust construction provides excellent resistance to UV exposure, frost, temperature fluctuations and mechanical stress, ensuring consistent operation in all weather conditions with minimal maintenance.
This version is supplied with an 18” square butylene fleece flange, which must be bonded to the roofing membrane using a suitable adhesive or primer. When correctly installed, the fleece flange forms a continuous, watertight connection between the roof membrane and the drain outlet, delivering reliable protection against water ingress. Suitable for both new build and refurbishment projects, the Kisner KADS Parapet Drain offers a durable and professional drainage solution for flat roofs.
