200mm Twin Wall Flue Pipes

Twin wall chimney flue systems are used when there is no constructed chimney available. They’re generally used in new build properties built without chimneys, but also in conversions and renovations where the chimney stack has been removed or the wood-burning stove’s desired position is not where the chimney is located.

An insulated flue system is a lower-cost alternative for removing the smoke and flue gases from wood-burning and multi-fuel stoves than building a stone or brick chimney. Our HETAS-approved 8-inch or 200mm twin wall flue is simple, clean, and easy to install — it requires only a competent person to fit; such as a HETAS-qualified installer.

Double-walled twin wall flues of any size can be used both indoors and outdoors and often pass through walls, floors, and roofs. The twin wall flue system is waterproof, corrosion-resistant, and is made from stainless steel but it can be powder coated black to suit your style.

There are 8-inch twin wall flues to suit any requirement in this range, whether it be long, short, or adjustable lengths, or for 15, 30, or 45 degree angled bends. We also supply 5-inch, 6-inch, and 7-inch flues for smaller burners, as well as a large selection of flashings, brackets and chimney pot cowls.
