The Areco Parapet Wall Flat Roof Drainage Outlet is a smart and durable solution for efficiently directing rainwater from your flat roof through a parapet wall or upstand and into a connected downpipe. Designed for modern flat roofing systems, this outlet helps prevent common water-related issues like pooling, leaks, and structural water damage.
Made from high-quality EPDM synthetic rubber, the outlet is built to withstand extreme weather conditions, making it a long-lasting addition to any flat roofing system.
Reliable Drainage for Flat Roofs & Parapet Walls
With a radiused 90-degree corner element, this drainage outlet is shaped to sit neatly through parapet walls or roof upstands. It’s predisposed for easy connector insertion and features a reinforced edge to enhance strength and sealing performance.
Additionally, the base is designed with a dovetail bas-relief, allowing it to bond effectively with bituminous roofing felts or membranes, ensuring a watertight connection between the roof and the outlet.
