Capabilities

Our strongest glass with virtually undetectable distortion.

For optimal performance in terms of wind-load resistance, thermal stress and impact choose from Vitrum’s line of heat-treated architectural glass products.

Our heat-treated glass is four times stronger than annealed glass, resists thermal breakage and is safer in case of breakage. We have the capabilities to fabricate heat-treated glass with minimal roll distortion, bow, warp or strain pattern. If you have any questions about our architectural glass products, contact us.

Certain shapes, unusual aspect ratios, and painted glass (screen or digitally printed, spandrel, etc.) may cause incorrect measurement readings and/or be unavailable in TrueForm. Glass with a low-e coating must be edge deleted prior to tempering, any variation from Vitrum’s standard edge deletion of 7/16″ (11mm) will negatively impact the leading and trailing edge distortion.
