Tinted glass is created by adding small amounts of metal oxides during the production process of clear glass. Their energy properties are not very different from those of clear glass, but it is recommended that they be heat treated to avoid the phenomenon of auto-reflection, as they have an increased energy absorption capacity. Tinted glass covers all the requirements of the market. They are available in 4 colour shades: bronze, fume, green and blue. The thickness starts from 3mm and goes up to 10mm
