In order to achieve a totally non-transparent glass pane, the spandrels are covered with ceramic paint, as is the decorative glass by the silk screen. Spandrels with the ceramic paint coating have the same features and application as decorative glass with silk screen and are available in the same palette of standard colours as well as the same dimensions.

• it is a perfect decorative material,
• due to the process of tempering, in which it is subjected to high temperatures that partially melt the paints into the glass, it takes on all the properties of tempered glass:
• it has greater resistance to bending in comparison to ordinary glass,
• resistant to thermal shock,
• reduces the risk of injury in the case of the pane breakage,
• allows for the selection of light inflow through the glass surface,
• reduces the effect of dazzling by direct rays of light,
• the layers of silk-screen are characterized by a high level of durability,
• it is classified as safety glass.

The possibility of use as a single pane, as well as assembling in double or triple glass units has led to the use of ceramic spandrels in the following building constructions:

 

The second widely used method of producing spandrels is covering the glass surface with a layer of silicon paint. After the paint has been applied, it is hardened by lamps. The glass must be machined and tempered before covering it with silicon paint. Spandrels with a silicon coating are com-monly used in areas of non-transparent facades of buildings. Realization of orders requires consultation with representati-ves of Press-Glas and the individual choice of colour coating from the RAL palette.
