About Us

About Us

Twin Wall - Flue Pipes is an established partner with regards to product development and manufacturing of stainless steel chimneys and flue pipes. We provide both stainless steel chimney kits, made of high-quality stainless steel, as well as individual components, which can be packaged together to fit the individual needs of our customers. Our chimneys and flue pipes are made from temperature-resistant metals and have been explicitly designed to fit the needs of any project.

Chimney Assembly

When installing the double-walled stainless steel fireplace, you can mount the stainless steel chimney either on a socket / base on the floor (floor installation) or on the wall (wall installation) with a base support. Various base supports are available with different contact surfaces and wall spacings. For the wall installation, the base socket of the stainless steel chimney with condensate drain is screwed onto the base support. For the floor installation, the floor plate is attached directly to the foundation / ground. From the structural conditions, such as the connecting height of the connecting cable and the height of the chimney base, it is determined where the 90º tee is fastened.

    "Even before the purchase I received very good support in advance."

    Best quality at a fair price! Initially, I wanted to buy the chimney locally, but I quickly realized that I could get a higher quality chimney at a fraction of the price compared to local sellers. It also comes with superb expert advise. Thank you!

    "Very impressed!"

    First off all, thank you for the great service. The chimney is mounted and just in time for the winter season. We will definitely recommend you! The experience of such a great personal service is very rare nowadays.

    "Easy installation"

    My colleague also ordered via Twinwall-Fluepipes and was very satisfied with the easy installation. Now I can also say that installing their flue pipes is a breeze.
