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".

Black 5’ flue kit

I purchased the black 5’ flue kit as the price was cheaper than any where else I could find for all the pieces in the kit.
Communications with Stovefitters was fast and efficient when arranging my delivery date. Everything turned up on time and in excellent condition.
The whole kit is delivered on a pallet inside a box to protect it all.
I will use again and also recommend them to anyone interested in twin wall flues.
