We are the only cast glass company to manufacture all existing types of cast glass.

All our products are solely manufactured in our main factory in Wunsiedel (Upper Franconia, Germany) according to the highest quality standards by a workforce that fosters family tradition. It is a matter of course that we are certified in compliance with the Quality Standards DIN ISO 9001:2015, 14001:2015 and 50001.

In addition, we ensure the highest possible environmental sustainability (EcoGlass) during the production of our standard glasses. The outstanding environmental standards in our line of business are underpinned by the current environmental statement as well as the Environmental Product Declaration (EPD) according DIN EN ISO 14025/EN 15804.


Our profiled glass is used in the most sophisticated architectural projects around the world. Since 2001, we are the first cast glass manufacturer to offer LAMBERTS LINIT U-Glass as standard – in lengths of up to 7 meters – as tempered safety glass with or without colored enameling or sandblasting.

EcoGlass / Ecology

LAMBERTS is the first and only cast glass company in the world to manufacture all glass types using an oxygen-fired melting furnace which is the most ecologically sustainable method available. This pioneer step was already implemented in the nineteen-nineties due to our deep conviction that production processes should be evaluated and improved in terms of environmental friendliness.
