Twin wall: LONG base support unit adjustable with brackets (15-37cm from wall to pipe)

Doing it yourself? Visit our "How to install twin wall flue" page.

Materials always in stock (4 UK-wide depots). 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.

EXTENDS TO A MAX. 37CM (FLUE FROM WALL)

Base support units can also be fitted "upside down". This is useful when you want the main body of the unit above your "hole through the wall" and out of the way of any cosmetic plate (if used).

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".
