Three-dimensional metal grids integrated into the IGU cavity that reflect high-angle direct solar radiation while admitting diffuse daylight. Four variants tuned for facade orientation, sun angle, and grid visibility. All hermetically sealed, permanent, and maintenance-free.
OKASOLAR's three-dimensional metal grid is geometrically tuned so that steep-angle direct radiation (the high summer sun that overheats a facade) is reflected back out before it reaches the interior. Lower-angle diffuse skylight passes through the cavity and into the room.
OKASOLAR achieves solar control through the three-dimensional shape of its metal grid, not through a tinted coating. Views out remain clear, color rendering stays neutral, and the glazing performs the same way year after year without coating degradation.
The grid sits inside the hermetically sealed cavity. No exterior shading device, no moving parts, no cleaning access required. The building facade remains a single flush plane, with the solar control built invisibly into the glass.
The grid geometry changes between variants: OKASOLAR F for facades, P for directional privacy, S for roof and overhead glazing, 3D for complex overhead geometries. Specifying the right variant for each building elevation delivers the highest performance.
Each OKASOLAR variant uses a different grid geometry optimized for a different orientation and solar angle. Reference specifications below; specific performance values depend on glass build-up, cavity dimension, and coating selection. Final specs confirmed on request.
Values are estimates from OKALUX published data. Project-specific values vary. Consult R. Suare for design-phase spec coordination.
Each OKASOLAR variant is engineered for a specific glazing condition: facade orientation, overhead exposure, or a dual privacy/daylight role. Pick by where the glass goes and what the sun does there.
Overhead glazing where direct sun must be blocked but diffuse daylight and partial sky view are essential. S uses horizontal louvres tuned to overhead sun geometry; 3D uses a three-dimensional grid that passes diffused light while eliminating direct transmission.
South facades with high summer sun and useful winter gain. F's O louvre type redirects daylight deep into the room while reflecting direct solar irradiation; U type reflects more irradiation outside. Both can combine in one unit.
P handles directional privacy on urban facades: vertical louvres that stay transparent one way, screened the other. 3D handles custom overhead geometries: sports halls, complex roofs, multi-directional sun. Both are project-specific.

OKASOLAR-specific documentation. Email-gated: we share your download request with OKALUX so they can send additional project-specific material if relevant.
We'll send samples, variant-specific spec sheets, and a project-matched Ug/TSET recommendation within two business days. For design-phase support, schedule a lunch & learn or send your solar study for review.
