- Advanced corrosion-resistant design and construction using 0.6mm 316L continuously-welded stainless steel. The only stainless steel system to have passed the internationally recognised GASTEC corrosion test.
- Engineered-tolerance joint simply push-fits together giving exceptional load bearing capacity. Optionally, a locking band can be fitted for extra joint security.
- Inward bead on the male joint spigot acts as a capillary break preventing moisture being drawn through the joint.
- Adjustable 0-90° elbows quickly solve alignment problems on installation of flue runs.
- Can be painted if required.
- For condensing appliances a gasket is fitted to the inward bead of the male joint.
Schiedel BIM Catalogue
A range of Schiedel Products for Commercial and Residential are now available within our new 3D BIM (Building Information Modelling) Catalogue.
Engineers, planners and architects now can have an significant influence on making Schiedel the choice of the chimney at the beginning of the planning process, with the comprehensive data available for a range of components.
All BIM and AEC CAD formats, like Autodesk Revit, Nemetschek Allpan and Grafisoft Archicad for the respective CAD systems are available to engineers, planners and purchasers for free. You can add these formats under your own account section. Schiedel BIM is free to use and you just need to enter your email address to register and download your formats (for free!).

Chimneys are subject to significant corrosion attack by flue gas condensates, particularly from solid fuel heavy oils and condensing appliances. Prima Plus and Prima Plus 1mm are specifically designed and manufactured to resist this corrosion. It is the only stainless steel single wall chimney system in the world to have passed the internationally recognised Gastec corrosion test.
