NO NARROW LOCKING BAND REQUIRED

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".
