If you are installing a new heating appliance, such as a woodstove, gas coal-effect fire or an oil boiler, you will probably need a twin wall flue  system, certainly if you do not have a brick chimney stack. Twin wall systems can be constructed to produce a safe chimney system for your appliance.

Twin wall flue pipes are  suitable for the creation of both indoor and outdoor flues and they can be used to pass through roofs and floors. Our double wall flues are suitable for use with wood, coal, gas and oil appliances. Our Twin wall flue system is also perfect for biomass boiler installations.

The outside diameter of twin wall flue pipes is 50 mm more than the inside diameter. So a 150 mm mm pipe has an outer diameter of 200 mm.
