The radiation cone visible directly in the planning tool
A new folder, “BKH green_Strahlungsbereich_DIN_16510”, is now available in the planning tool. It contains all BKH green fireplace inserts, each with its individually calculated radiation zones. In PaletteCAD, the files can be found in the BRUNNER catalogue under: BRUNNER → BKH green → BKH green_Strahlungsbereich → corresponding product series (e.g. corner, flat, Panorama, tunnel).
The key advantage: the radiation cones are displayed in three dimensions – to the sides, upwards and downwards. In addition, different glass variants are clearly distinguished:
- Yellow area: uncoated glass ceramic
- Blue area: heat-reflective coated glass ceramic with reduced radiation zone


Already during the planning phase, it becomes clear whether the colour-coded radiation cone intersects with combustible areas of the floor or the surrounding walls. This allows the position of the heating insert to be checked and adjusted at an early stage. If repositioning is not sufficient, it also becomes immediately visible which areas may need to be designed as non-combustible in the worst-case scenario.


Visualization of the radiation zone in accordance with DIN EN 16510 in front view: the blue area represents the reduced heat radiation with coated glass ceramic, while the yellow area shows the greater extent with uncoated glass ceramic. It clearly illustrates how the installation height of the heating insert must be chosen in order to avoid additional protective measures with combustible floor coverings (e.g. tiles or slate – but note: no glass). A fire table can further reduce the radiation cone (red line), thereby expanding the planning flexibility.
More safety, less coordination effort
For stove builders, this means that the positioning of the heating insert can be optimised directly within the digital model. Areas that need to be executed as non-combustible can be identified immediately – or avoided altogether by adjusting the system configuration.
Selecting the appropriate glass variant also becomes much easier. Whether standard glass ceramic is sufficient or a coated version is required can be assessed directly within the planning tool.
The radiation zones integrated into PaletteCAD are based on the official BRUNNER planning guidelines for DIN EN 16510 and are precisely calculated. This makes them not only a powerful planning tool, but also a transparent and reliable form of documentation for chimney sweepers and endcustomers.
As a result, planning becomes not only faster and more transparent, but also significantly safer.
Expert advice
Keep the radiation zone in mind from the very beginning. Integrating the radiation cone early in the planning process helps avoid later adjustments, increases planning reliability and provides a solid basis for coordination with the chimney sweep.
