Stopsol is characterized by excellent photometric and energy performance. Stopsol is a reflective glass produced on the parsol surface by a pyrolytic process which means that during the production of glass, the mass is warmed, and by spraying a layer is applied on selective metal oxides which are sunk in the mass.

Reflective layer is permanently protected by a glass mass and is not subject to any changes in the properties of any form in passing of time. Its highly reflective outer surface makes it a common choice when you need to cover the interior space from passers.

It should be noted that the effect of reflection depends on the ratio of internal and external illumination quantity of light. In other words, at night, when it is dark outside and the inside of the room is illuminated by artificial light, glass is transparent (as viewed from the outside), while during the day when it's sunny, glass is reflective (mirror effect - seen from outside).

In addition to solar factor, energy factor in bundle often additionally enhances the glass.
