How important is the glass in a stove?

With a stove or fireplace insert, the right combination of materials and technology is crucial for optimum heat output and a beautifully burning fire.

Each individual component must reliably fulfil its functions.

The fire viewing window is a hard worker when it comes to performing such functions. In order to guarantee safety, it must reliably withstand extreme temperature differences from room temperature to over 700°C. It must also emit the right amount of heat into the living space and always provide the product user with a clear fire view without soot deposits. If you pay attention to the quality of the glass ceramic pane and its installation in the firebox door when buying a stove or fireplace insert, you will avoid disappointment later on.

How can you recognise a good glass ceramic pane?
The manufacturers of wood-burning stoves purchase glass ceramic panes from various manufacturers, although the quality varies greatly. Unfortunately, you can only tell how good a pane is when it is in operation (once the stove has been purchased and installed).

If you want to play it safe at the time of purchase, it is better to invest a little more in your new stove, because: The more expensive the stove, the higher the quality of its glass! This equation becomes clear when you realise that high-quality products use glass ceramic panes with special coatings and functions, which are by far the most expensive individual components in the manufacture of stoves and fireplace inserts. In return for the slightly higher price, you get a particularly beautiful, clean fire and a clear fire view. When buying, be sure to pay attention to the way in which the pane is installed in the stove door, as this is important in terms of stability, tension tolerance and tightness.

The following features are not necessary for every stove, but - if present - can clearly be regarded as disc quality features:

Infrared-coated glass ceramic panes
Infrared coated glass ceramic panes reflect 7 times more thermal radiation back into the firebox than conventional firebox glasses. This increases the combustion temperature in the firebox, which means greater energy efficiency, less wood consumption, even cleaner glass and beautiful flames with the best emission values.

Double glazing
A firebox door with double glazing insulates and has a dual effect. Firstly, the thermal radiation to the outside is reduced. This prevents the living area from overheating.

Secondly, the heat remains in the firebox, which means that a beautiful fire burns with little logs and even at a low heat output. Both of these benefits are particularly important in modern, well-insulated low-energy and passive houses.

Window rinsing
The window rinsing technology helps the glass ceramic panes to stay clean. A sophisticated flow system guides preheated air in the firebox precisely over the fire viewing panel. This air flow literally flushes away soot deposits on the pane - the pane stays clean!

So if a clean pane is important to you when watching the fire burn, you should take a close look when buying a stove. Ask your dealer to explain the glazing concept of your dream stove to you and show you how it works. You can find an Attika dealer in your region here.
