In the Okasolar 3D glazing unit, an aluminium grid places between the glass at an angle. Aluminium has a high degree of reflectivity. The plastic cross bars also have a reflective coating.
A lighting laboratory calculated the angle of the slats, the spacing and the cross-sections.

The grid does not need to clean because it covered with glass.
As the result is a daylighting system that prevents direct sunlight at any time of the day or year. Even when the sun is low in the east or west, there should be no side radiation.
The system uses in a single or double glazed unit. According to the company, a standard single glazed unit Okasolar 3D consists of
- outer pane made of thermally treated glass,
- 24 mm cavity with integrated sun protection grid and gas filling,
- inner pane: LSG or Heat Strengthened Glass with Low-E coating.
