Narrow Boat Twin Wall Flue Kit MB

PLEASE NOTE: The diameter advertised refers to the internal measurement of the flue, not the external measurement.

This narrowboat flue kit is a high-quality twin wall system designed for use where an insulated twin wall flue passes through the deck of a narrowboat.

It provides a safe and professional solution for deck penetrations, allowing you to install a stove or appliance in locations where a traditional masonry chimney is not present. Designed with both performance and ease of installation in mind, this system ensures a neat finish while maintaining safe clearances to surrounding materials.

With its durable construction and matt black powder-coated finish, it integrates seamlessly with our black twin wall flue systems, delivering both reliability and a clean, modern appearance.

Twin wall systems are commonly used in narrowboat installations due to their insulated design, which helps to reduce heat transfer and allows safe installation through structures such as decks and roofs.
