This twin wall insulated flue system has been designed for a double storey straight flue with an offset. In this system the Twin wall adapter can connect directly to the stove collar or a short piece of stove pipe (not included) which starts the system. The flue passes through 2 floor levels and all the firestop kits and finishing plates are provided accordingly. Once the straight flue passes in to the loft it goes through the roof level supported by an adjustable roof support and terminates through the roof, passing through an adjustable flashing and finishing off with a rain cap terminal. The offsets can be used anywhere suitable within the system to create the optimum termination for the flue, in most cases this is in the loft space purely for aesthetics. Please see our offset chart for more information.
