ISSOL® Square
Maximum energy efficiency without compromising on design. ISSOL® Square seamlessly integrates high-performance solar cells into a clean grid pattern, offering fully adjustable transparency for skylights and façades.
Light, Shade & Energy
ISSOL® Square is the definitive solution for overhead glazing and curtain walls where natural light is essential. By adjusting the spacing between the solar cells, architects can dial in the exact transparency level needed (from 0% to 100%).
This active glass acts as a solar shading device (reducing cooling loads) while generating clean energy, turning atriums and canopies into functional assets.
