Chromatics glass is thermally safe

Thermally safe

This exceptional level of performance makes Chromatics thermally safe in virtually all external applications.

Typically, architectural glazing is subject to stress and consequent fracture as a result of localised expansion caused by temperature differences within the glass.

The method for measuring the thermal strength of glass is to compare the calculated maximum temperature difference the glass will encounter in its glazed situation with the safe temperature difference for a given type of glass. If the safe temperature difference exceeds the maximum temperature difference then it is considered fit for purpose.

For annealed float glass, the accepted safe temperature difference is calculated as 40°C. For Chromatics, it is an impressive 51°C, improved even further by the mechanical strength of the laminate, which acts as a ‘stress relieving factor’ (SRF) that, when included in the calculations to establish thermal safety, has the effect of enhancing the safe temperature difference by a multiple of up to 1.5.

For complete peace of mind, an indicative thermal safety evaluation is recommended at the concept stage of the building design process, bearing in mind the particular application and location of the site.
