Vent Pipe Prefabs

Scope of Application

This is a single-piece injection-molded roof vent specifically designed to expel moisture from insulation layers. It features a broad welding base and a top anti-backflow cowl. During installation, the base is welded to the underlying waterproof membrane, and the cowl is then fitted to complete the assembly.

Technical Advantages

• The straight base and broad welding zone are injection-molded as a single piece, completely free of joints or seams

• The detachable cowl design ensures rain protection while allowing convenient future inspection and maintenance of the pipe

• The overall design effectively resists temperature fluctuations, wind loads, and foot traffic, with excellent anti-aging performance
