SODALIME GLASS
CONTARDI TEMPERED

Sodalime glass

Soda-lime glass is used in all those applications where there is a need to observe something without touching it or as a protection, where the temperature of 150°C is not exceeded, so for low-pressure sight windows and machinery protections glass. If the glass should break because of the temperature, it would break into small pieces. Soda-lime glass is supplied in sheets or rings, in accordance with customer specifications.
