Chimflue supplies and supports the widely used 6 inch twin wall flue, a size that is standard across many residential, commercial and industrial applications. Recognised for its versatility and performance, the 6 inch system is suitable for a wide range of building and process requirements. We offer supply only, supply and design packages, and installation if required.

Our 6 inch twin wall flue systems are designed with durability, safety and efficiency in mind. The twin wall insulation maintains stable flue gas temperatures, reducing heat transfer to surrounding structures and ensuring regulatory compliance. This makes it a trusted solution for projects in sectors such as housing, hospitality, education and industry.
The system includes a comprehensive choice of components — from lengths and bends through to supports, terminals and specialist adaptors. Each part is precision-engineered for secure connections, long-term stability and straightforward installation.
At Chimflue, we adapt to the requirements of each client. We can deliver products on a supply only basis, provide technical assistance through a supply and design service, or offer a fully managed installation. Our experienced teams ensure each flue system is integrated safely and efficiently into your project.

With decades of experience, Chimflue is trusted across the UK for reliable products and technical expertise. Our 6 inch twin wall flue systems combine compliance, performance and adaptability for projects of all scales.
