The Service (within 5 working days)

twin wall chimney systemWe have been designing twin-wall chimney systems since 2007 (in winter we will often do 5-10 designs a week).

We use our own twin-wall design software which is accurate to within millimetres.

We strive to make the procedure as simple & stress-free as possible.

We do not install but you can self-install or find one of our listed and registered installers.

Peace of Mind

twin wall systemDesign process includes any design changes as required should the need arise.

Email, Live Chat or SMS support during all stages including installation phase.

We do not charge for the design process - just for the parts.

There is no obligation to purchase. We care that you are pleased with the service but do not worry if you do not purchase. I (Julian) personally create or oversee (with colleague Ray) all drawings and send a drawing and quote and then forget about you unless you make contact :-) We don't keep tabs on who orders and who does not. Our job is to give you a great quote and drawing.

Trade reviews

Review by Hetas registered installer D. Parker: Firstly – Dura Twin Wall is brilliant to use and the kit is absolutely fantastic! Better than Dinak and Poujoulat. Will be doing a brilliant review once finished.

Review by Leon - ELB Fireplaces: The products are the best I've ever used. The flue liner is extremely strong and with its multi direction flow it's perfect. The Duratwin twin wall is for me their best product with its push together system not twist and lock it makes life an installer that bit more easier. It has reduced the installation time which is a big bonus to any company and with the sleek black finish it just finishes the job perfectly. I would advise any company to give it a try.

NUTEC Stove & Kitchen Company Ltd : We have now used Duraflue Twinwall on 5 jobs and continue to be impressed with both the sturdy design as well as the quality of fit, especially when compared to other models available. We have just about used part and will continue to do so going forward as nothing comes close. Really impressed with Julian and Arran who constantly look after us.

Twin wall chimney components

The ordering of these parts was simple as the website is easy to use. I could examine all dimensions of each part through a couple of clicks, essential when analysing which sections to purchase. Staff were available to answer queries at every stage. Once ordered the parts arrived two days later, shipping and delivery information was announced at every part of the process. Delivery on a pallet meant that the goods were easily manipulated into a convenient position on my property. Packaging was substantial. I would definitely recommend your company to others. Thank you.

Amazing Service

Can’t say how helpful everyone is, their knowledge and customer service is brilliant combined with very competitive prices and excellent products (purchased woodturner & clip together chimney, purchased with excellent telephone advice) makes this company an absolute winner!

£ PRICE MATCH £

We will happily strive to match any price you may have from any other supplier as long as the other supplier has it in stock.
Offered an "ex-display" or "shop soiled"? We will strive to offer you a new stove for the same price.

Already have a chimney? You need 1. Stove 2. Liner 3. Fitting Pack 4. Chimney closure plate (Hardiebacker board from Builder's merchants or galvanised sheet).That's it!
No chimney? Check out our shed kits or let us design your clip-together chimney design - easy peasy.
