At a glance
The power package for your fireplace: ROBAX® Energy Plus is the first glass-ceramic fire panel with a heat reflecting coating. It is available in a flat version as well as in a rounded form for the first time. The advantage is an energy-friendly fireplace: While visible light can easily pass through the panel, some of the heat radiation is reflected back into the combustion chamber. This can result in a noticeable gain in stored energy – ROBAX® Energy Plus.
Product benefits
Up to 35 % of the heat radiation is reflected back into the combustion chamber. The result: the energy radiation passing through the panel is reduced and the temperature in the combustion chamber is significantly increased. The extra energy gained can be used for more efficient heating water conduits or as additional stored energy.
The higher temperatures in the combustion chamber generally causes better combustion and results in lower emission values.
Even when the heat runs high, ROBAX
® Energy Plus is resistant to high temperatures. The temperature resistance is approximately 650 °C (1,202 °F). The efficiency of the coating is therefore maintained over time.
The coating can result in less soiling on the panel, in particular due to soot, which makes cleaning the glass-ceramic distinctly easier.
The reduced radiation means that the installation area is heated more pleasantly and evenly. Moreover, the floor temperature in front of the heating appliance remains cooler. This means that furniture can be placed closer to the visible area of the appliance, thus offering increased enjoyment of the fire experience.
The SCHOTT application technology laboratory guarantees comprehensive application servicing.
* All the above effects are of course heavily dependent on the construction of the individual stove and its normal usage. We strongly recommend that you check whether ROBAX® Energy Plus delivers the results you are looking for before you opt for a standard model.
Advantages
- The lower heat radiation emitted, especially with large fire viewing panels ensures a constantly pleasant room temperature
- Constant performance of the coating over the entire burning period
- The coating does not distort the view of the fire.
- As a result of the heat reflection into the combustion chamber and the associated high temperatures of the combustion process, soot deposits on the fire viewing panels can be reduced
or do not occur at all. This means less cleaning and an unobstructed view of the fire.
- By the reflection of the heat radiation, the available heat energy can be used more efficiently and more sustainably, e.g. for water-bearing fireplaces or as additional storage energy. This means
that in the ideal scenario, heating costs can be reduced.
- Higher combustion temperatures can contribute to the reduction of emissions.
- More design possibilities, especially with regard to fireplaces with side glazing and large fire viewing panels

Cumulative reflection of heat radiation for a wavelength range of 800 to 8,000 nm.
Both the embers and the fire in a fireplace emit heat/infrared radiation (typical wavelengths from 800 to 10,000 nm). ROBAX® IR Max reflects seven times more than a non-coated ROBAX® fire viewing panel. The wavelength range in the evaluation was from 800 to 8,000 nm of the reflection spectra. Conditions and equipment remained constant throughout the testing process.
* The effects mentioned in this text are largely dependent on the design of the respective fireplace and the usage habits. We therefore strongly recommend to test whether ROBAX® IR Max can achieve the desired result before committing to serial production. ROBAX® offers comprehensive application services. Please contact us.
The anti-reflective coating applied on both sides of the glass is available for flat ROBAX® fire viewing panels. It helps to avoid reflections from the area surrounding the fireplace and, thus, facilitates the best possible view of the heart of the fireplace. We recommend using ROBAX® TrueView only with gas devices.

ROBAX® Magic glass-ceramic panels have thermal, physical and chemical characteristics, which make them suitable for use as highly resistant interior paneling for gas stoves and gas fires for domestic heating in private homes. More prolonged periods of contact with flames should be avoided. ROBAX® Magic opens up new design options for improving the appearance of room-heating devices that require low thermal expansion and high temperature stability. The impression of additional reflections created by the dancing flames and the ease with which glass-ceramic panels can be cleaned make ROBAX® Magic a real alternative to the conventional materials used inside combustion chambers.
ROBAX® Magic is available in black, grey, white and translucent white. More colors are available upon request. The surfaces of ROBAX® Magic are nubbed on one side and smooth on the other.

Thanks to their thermal, physical and chemical characteristics, ROBAX® Ambience glass-ceramic panels are intended as durable outer linings for stoves and fireplaces in private homes. ROBAX® Ambience opens new and large-area design options for enhancing and beautifying room heating devices that may require low thermal expansion and high temperature resistance.
ROBAX® Ambience can be custom-decorated with a large selection of ceramic colors. The material colors of ROBAX® Ambience are black, grey, white and translucent white. The surfaces of ROBAX® Ambience are smooth on one side and smooth or nubbed on the other side.

ROBAX® Mirror: This reflective layer is only offered for flat ROBAX® fire viewing panels. When no fire is burning, the reflective pane prevents the often dirty inside of the fireplace from being viewed to a large extent. When a fire is burning, however, viewing is excellent. The reflective layer is found on the side that faces away from the fire. The uncoated side is indicated for purposes of installation.
