The secret to solidity


Since 1945, Duralex has pioneered tempered glass technology, a process that we specialize in. Our factory in La Chapelle-Saint-Mesmin was the first one in the world to
produce tempered glass tableware.

Thanks to continued investments and commitment to quality, Duralex has achieved its high standard of excellence which makes the brand successful throughout the world. Our company is incontestably recognised as the tempered glass leader.


The tempering process is what makes Duralex glass so tough. Glass that has been heated to around 650°C is suddenly cooled by cold air ventilation. This treatment creates controlled stress in the glass which improves most of its physical qualities: resistance to mechanical stress and thermal shock (sudden change of temperature). Duralex glass is at least 2.5 times more resistant than non tempered glass products. It withstands a minimal thermal shock of 130°C. It is the same tempered glass used to make windscreens which, in the event of an impact or accident, shatter into thousands of non-cutting pieces

Duralex observes the European norm for thermal shock, one of the strictest standards, and even goes beyond its requirements. Duralex products resist a minimal thermal shock of 130°C, and up to 200°C for ovenware products.


Duralex tempering process improves mechanical strength and thermal shock resistance.

Fully tempered glass is safer, tougher and therefore more durable than partially tempered glass. Full tempering guarantees a better resistance of the whole glass in addition to a full safe fragmentation in case of breakage.

Our constant commitment to quality and regular controls allow us to guarantee a stable tem

Duralex fully tempered glass is 2.5 times more resistant than non-tempered glass.

Duralex glass is safe: when a shock or a series of shocks manage to break one, it shatters into small non-cutting pieces

Duralex tempered glass is the preferred choice of the food service industry. Practical and durable, it allows time and space saving and offers better return on investment as it lasts longer and does not need to be replaced frequently. It is specially recommended for intensive use, indoor and outdoor. In addition, its resistance makes it safer for hospitality environments. This is the main reason why it has been widely used in the French canteens for decades.

Duralex tempered glass resists a minimal thermal shock of 130°C.It can go up to 200°C for specific categories like ovenware. Duralex products can withstand temperatures between -20°C and up to 300°C.

Duralex glass is 100% hygienic: in addition of being non porous, it is lead, cadmium and BPA free.
