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.
| Heat-Strengthened | Tempered Glass | TrueForm™ Premium Tempered Glass | |
|---|---|---|---|
| Features | 2x’s stronger than regular (annealed) glass | 4x’s stronger than regular (annealed) glass | 4x’s stronger than regular glass with virtually no deductible distortion |
| Surface Edge Compression | 7,500 PSI | 10,000 PSI | |
| Break Pattern | large pieces, which may stay in the glazing pocket, decreasing probability of fallout | small pieces which tend to fall out of the glazing pocket, more so than heat strengthened or annealed | |
| Safety Glazing | no | yes (ANSI Z97.1) | |

| Minimum Size (3mm) | 5″ x 9″ (127mm x 229mm) | 5″ x 9″ (127mm x 229mm) | |
| Minimum Size (>4mm) | 3″ x 9″ (76mm x 229m) | 3″ x 9″ (76mm x 229mm) | |

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.
