Twin wall: 90 degree tee (requires soot collection door). Rarely ordered part.

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 offer a full Twin Wall Design Service with all designs prepared within our Twin Wall Design Studio. Contact us for further details (info@stovefitterswarehouse.co.uk).

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.

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".

Twin wall Flue

Fitted a twin wall flue for the first time, the parts fitted together with ease and were very self explanatory. Had a couple issue whilst fitting, but just rang up for advise and had great service in return.

Good product, but...

I've used this type of flashing before on plastic pipe. I do like the product but the instructions aren't great. There is a fitting video on their website which helps. Make sure you cut the hole smaller and give it a test. If you go by the numbers on the collar you may cut it larger than required. I'm sure mine will be water tight but I'll keep a close eye on it. Cheaper and easier to fit and seal than the lead and storm collar combination though.

Stovefitters- second to none!!

Stovefitters warehouse have been brilliant!
We sent Julian some simple drawings and measurements and he designed us the perfect systems for two wood burning stoves, complete with list of parts and a computer produced diagram of the finished article. They then put the order together which we received promptly and we’ll packaged. Great British made quality too! The twin wall Duraflue is very nicely made with very clean lines and is very simple to install.
We changed our mind a couple of times but nothing was too much trouble.
Julian and Arran dealt with our issues promptly and very professionally. Their knowledge about stoves and flues is second to none!
We are extremely pleased with the goods and service we received. We would not hesitate in recommending them to family and friends. They work very hard and customer satisfaction seems very high on their list of priorities.
All now installed the stoves look and perform great! Thank you to all Stovefitters Warehouse!

Quality product, great advice and delivered quickly

I ordered a few different twin-wall components for my installation after speaking with one of the guys at The Stove Fitter's Warehouse for advice. After a run through of my installation queries over the phone, I received great advice and help with my order.
