Passive solar shading, built into the glass.

Project Case

Lapp GmbH

A facade renovation in Basel, replacing heavy tinted solar control glass with MicroShade® micro honeycomb insulating glass. The brief demanded equal or better solar performance without reverting to a coloured product. The result is a brighter, more comfortable building with a clean, neutral facade that will last for decades.

Comfort and clarity, without any systems or screens

The atrium facade at Lapp GmbH’s headquarter needed to balance two demands that often work against each other: a genuinely comfortable indoor climate and an uncompromised, transparent glass facade. For a modern, energy-conscious building, neither could be sacrificed for the other MicroShade® was integrated directly into the inner face of the outer pane, automatically adjusting light and energy transmission throughout the day as the angle of the sun changes. The shading requires no manual control and operates entirely autonomously, making it a natural fit for a building designed around energy efficiency.

By effectively blocking solar energy in summer, the facade stays comfortable while remaining fully transparent, with natural daylight flowing through uninterrupted. With this performance built into the glazing, no external shading devices were needed, leaving the architecture of the building completely untouched. With g-values between 8 and 15 percent and light transmittance of 50 to 60 percent, the result is a carefully balanced specification between solar control and daylight.

The shading itself is barely perceptible. Only on close inspection is a faint line visible where the sheets meet. As a passive technology with no mechanical or electrical components, it requires no maintenance and remains highly cost-efficient throughout the lifetime of the glazing.
