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).

Stove Fitter's Warehouse offers a full Twin Wall Design Service with all designs prepared within our Twin Wall Design Studio: https://www.stovefitterswarehouse.co.uk/products/chimney-design-to-building-regulations

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".

Great product and easy to fit

Order number 13306. I purchased this nu-lead part for my log cabin and wanted an easy product that incorporates the lead flashing as well as the rubber seal for the output chimney.
This product was perfect and very well made, it’s easy to fit and the lead is pliable that you can mould it into place in and around the roof tiles. Mine was felt so o removed an area of tiles and tucked the lead flashing underneath.
All in all a great product for the job and brilliant service from the guys at Stovefitters. Will be coming to you guys for any future stove requirements.
