Twin Wall Flue
Our stainless steel or black twin wall flue pipe is a simple push fit joint flue system, build your chimney system by placing each piece on top of the previous and push together to make the joint (the simplest system to construct on the market today). This twin wall flue system is suitable for use with wood, coal, gas and oil appliances. If you are installing a new heating appliance, such as a wood or multi fuel stove, gas coal-effect fire or an oil boiler, you will probably need a twin wall flue system, especially if you do not already have a brick chimney stack.
