Performance and properties of the glass elements
SWAREFLEX reflectors employ the principle of retro-reflection: if a beam of light hits a retro-reflective optical system, it is reflected back to its point of origin, irrespective of the direction from which the beam strikes the reflector. The shape of the glass element is calculated precisely by computer to achieve optimum reflection. The backs of the glass elements are finished with a highly reflective, silvered, mirror layer and several special protective over-layers.

As a reflector is subjected to enormous mechanical stress from vehicles, its surface must be as resistant as possible. Glass is the best material for this type of load. |

Depending on their respective fields of use SWAREFLEX glass elements are embedded in a variety of plastics, which have proven to be perfect for outdoor use. The advantages of SWAREFLEX glass reflectors: - Low loss of reflection intensity compared with reflectors made of other materials - High resistance to breaking and scratches - Outstanding resistance to heat (up to 95° C), cold and UV light - Good resistance to chemicals (de-icing salt, oil, petrol, cleaning solutions, etc.) - Highly economical due to durability |
