The Vaillant Flat Roof Penetration Collar creates a secure, watertight seal where a vertical flue passes through a flat roof. Designed for use with Vaillant ecoTEC domestic and commercial boiler flue systems, it helps protect the roof structure from water ingress while providing a neat, professional flue termination.
Suitable for homeowners planning a boiler installation and Gas Safe registered installers completing flue work, this genuine Vaillant roof flashing supports a clean, weather resistant finish around the flue penetration. Its robust construction is intended for external roof use, helping maintain long term protection at a vulnerable point in the building envelope.
