This is a twin wall clip-together chimney part used to build a new chimney. Twin wall clip-together chimney can be as close as 5-7cm to combustible materials (so is also useful for adding atop a stove to bypass a wooden beam).

1X NARROW LOCKING BAND REQUIRED

Stove Fitter's Warehouse offers a FREE Twin Wall Design Service.

Duraflue Twin Wall was launched to the market during 2014 and, due to its high quality and innovative design, is already a favourite amongst professional stove fitters. Brackets are strong whereas other brands may be spindly and quality is premium. Do it once - do it good.

Top tip: No fire cement or glue of any kind is used when connecting twin wall pipe to twin wall pipe - it is just push-fit (with a locking band for added security). When to use fire cement on flue joints? Use the SEARCH function and type "sealing flue joints".

Product great and huge help from the team as this was the first stove I had fitted. Only one issue with the 45 deg cover plate did not fit very well. Gaps around the pipe when installing and not a tight fit. All else good. Many thanks Dougie

Excellent experience

Couldn’t have been mmore helpful, from trying to resolve my delivery requirements to patiently answering my many questions.

Excellent communication, always prompt and friendly – and the website is a mine of information for anyone contemplating a DIY stove installation. I’ve fitted a lot of stoves, in a lot of different situations – houses, vans, trailers, boats – but I still learned a vast amount from SW’s extensive documentation.

As a bonus, I really appreciated being able to get everything I needed for my current project from one place.

Would definitely use again.
