DTW Nu-lead lead roof flashing 0-45 degree (recommended)

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

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).

Nulead is a simple and effective roof flashing with a lead base for twin wall flue and its high temperatures. This is the one I would fit on my house (Julian Patrick author of Stove Fitter's Manual). It is suited to all roof tiles but particularly suited to tiles that are not flat (e.g. Roman tiles or concrete tiles).

FITS ALL DIAMETERS 175-330mm SO IS FINE WITH ALL OF OUR TWIN WALL (YOU CUT HOLE TO SIZE LESS SCARY THAN IT SOUNDS).

Lead is 850mm x 550mm.

NO STORM COLLAR REQUIRED - THIS FLASHING IS COMPLETELY WATERTIGHT

A cheaper choice is the rubber aluminium flashing (ideal for flatter tiles such as slate). Search "rubber aluminium flashing" on this website.

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".

Flue and a wee Stove too

Genuinely helpful guys. Any reservations i had about going down the online diy route rather than the local store were soon put to bed. Worked with me closely on the flue design which apart from a few dimensions i knew very little about. Twin wall Duraflue went together with relative ease and feels very robust. Saltfire peanut 5 is a great wee fire, build quality is very professional and it looks great.

Duraflue flue

We ordered a complete flue to fit in our house in France. After doing some research online regarding the best make I had some questions and these were answered promptly by Stovefitters so we were confident we were ordering the correct product. The order was processed quickly and we received excellent communication throughout, the delivery arrived on time and each item was well packaged. The product itself is of obvious quality and we’re very happy. We’ll definitely be going back for a Stove when we’ve built our extension! Many thanks
