Twin wall Chimney Flue - Stainless steel

We are one of the UK's main suppliers of HETAS approved, insulated stainless steel twin wall flue pipe.  All sizes available at unbeatable prices. Our twin wall chimney flue systems are suitable for use with all types of fuels e.g wood, coal, gas and oil appliances. If you are installing a new heating appliance, such as a wood burner 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.

Our chimney flue is a simple push fit joint flue system - the simplest system to construct on the market today.

You can install twin walled flue virtually anywhere giving you more choice where you install your appliance. The flue is able to run internally and externally passing through floors or walls to accommodate your required flue route. Our twin wall flue pipe has been manufactured to the highest standard and also offers great aesthetics for your stove or fire place installation.

We can supply all sizes of twin wall flue including the most popular sizes: 5 inch (130mm), 6 inch (150mm), 7 inch (180mm) and 8 inch (200mm).  If you require bigger sizes, please see our Commercial twin wall section

Twin wall chimney flue - Black

Our Insulated twin wall flue pipe is also available in black.  In stock in sizes 125mm / 5", 150mm / 6", 180mm / 7 inch and 200mm / 8 inch.  Other sizes also available upon request.  The stainless steel finish twin wall flue can be used in conjunction with the black.  Simply mix and match on your run of flue.  You may prefer the look of our black chimney flue pipe internally in the first room as it matches well with their wood burner / multi fuel stove and then choose to join this to the twin wall flue with the stainless finish later in the vertical run which is more economical to buy.  Or simply use the black twin wall on the whole of your chimney run if you prefer the look of the black and are running the flue externally up the side of your building.
