Mirror Types

The whiter the glass, the higher the energy values. FLABEG uses an extremely white glass.
The newly developed generation of solar mirrors FLABEG achieves 93% energy reflection.

Glass Thickness
A glass thickness of 4 mm is the proven standard for achieving the requisite breaking strength. A thickness of 5 mm is recommended for edge areas exposed to wind. Normally, five to ten percent of a solar field is equipped with 5 mm glass.
