Toughened Safety Glass(ESG) METHERM®
individual ~ timeless ~ safe
ESG METHERM® of MENNES GmbH can be found in all industry branches. Our special glass features following advantages:
 more resistance to impact and pressure- ”Crumble effect“ in case of destruction, thus no risk of injury
- Thermal fatigue resistance up to 150 K
- Pressure resistance up to 900 N/m²
 Following kinds of glass can be thermally tempered (hardened) by us:
- Float glass
- Cast glass
- Coloured glass
- Whitr flashed opal glass
- Borosilicate glass
- et al.
The edge processing for the manufacturing of ESG METHERM® is by default delivered as seamed model.
Further processing such as C-cut, polished edge etc. is available on request.
Special refinements such as printing, glazing, drillings and cuttings may be realized easily.

Drillings
|
The distance between drill hole edges and glass edges and the distance between the drill hole edges have to be at least two times the glass thickness. In case of more than four drillings, please ask us for the minimum distance. When a drilling is placed in a corner of a pane and when a distance between drilling edge and glass edge is smaller than 35 mm, the difference of the distances has to be at least 5 mm. Correspondingly, the chart applies for the limit deviations.
