Heat Treated Glass

Description

Heat-treated glass is used to describe glass that has undergone a thermal process to increase the strength of the annealed glass. Heat-treated glass is used for its increased strength, which allows it to resist wind loads, temperature gradients, and impacts. In addition to heat-treated glass, Saand offers heat soaking which is a thermal process designed to potentially expose the nickel metal sulphide (NiS) inclusions in glass. While the process does not fully eliminate the potential for spontaneous breakage, it is designed to significantly decrease the likelihood.

Saand offers both heat-strengthened and tempered options. Industry standard ASTM C1048 defines heat-strengthened glass as having roughly twice the strength of annealed glass. When broken, it will fragment similarly to annealed glass but into fewer pieces. Heat-strengthened glass is not suitable for safety glazing as defined by ANSI Z97.1.  Fully tempered glass is described as having roughly four times the strength of annealed glass. When broken, it will shatter into small pieces. This reduces the likelihood of serious injury in the event of breakage. For this reason, fully tempered glass is defined as a safety product, by ANSI Z97.1.

Saand heat soaks in accordance with EN 14179-1 and uploads all process data for 3rd party monitoring and record retention. Saand will also be registering heat soaked product with the Safety Glazing Certification Council once program specifics are finalized.

Saand performs frequent, in-house testing to sample and validate production and ensure respective heat-treated characteristics are met. Both high volume and customized product is offered. Saand’s heat-treated process is certified by the Safety Glazing Certification Council.
