RETROSolar uses mirror-optic louvers that selectively redirect useful daylight deep into the room while reflecting excess solar heat back to the sky. This delivers glare-free illumination and passive cooling—without closing off views.

Standard blinds must close to cut heat, which darkens interiors and raises cooling loads. RETROSolar is designed to stay open, maintaining transparency and daylight while controlling heat. Compared with “smart-tint” glass, RETROSolar achieves similar SHGC cuts passively—no wiring, controllers, or firmware.

In open-plan offices, simply redirecting daylight can cut electric-lighting energy by at least ~50%, with additional savings from reduced cooling. In practice, projects have achieved up to ~30% total energy-cost savings and 80% daylight autonomy up to 5 m from the facade (≈500 lx).

Core performance is optical and passive—no drives, power supplies, or firmware required. Where occupant adjustment is desired (e.g., interior blinds), optional motorization/control can be provided; training includes electrician instructions.

By redirecting light to the ceiling, RETROSolar delivers glare-free daylight; near windows in winter, a simple interior roller-blind can block low sun while the upper daylight redirection keeps working. This approach supports transparency and helps meet workplace luminance guidance without darkening the room.

Yes—over 6.5 million ft² of completed daylight-control projects worldwide, including flagship museums, banks, labs, and offices. Case studies show high transparency (>80%), low inner-pane temperatures (~32 °C), and fast rollouts (e.g., 9,000 m² installed in 3 months).

RETROSolar louvers are produced on multi-stage roll-forming lines from coil stock, then punched and cut in-line—yielding precise, repeatable optics. Material thicknesses include ~0.2 mm (RETROLuxTherm micro) and ~0.3 mm (RETROFlex micro), with carefully engineered contours to minimize reflections and heat absorption.

Yes. In summer, the system reflects overheating sun outward; in winter, it redirects low sun to the ceiling for useful light. In triple glazing, SHGC values as low as 0.07 are achievable, while visual transmission of optimized systems ranges from ~56% to >85%.

Exterior blinds (RETROLux A), interior blinds (RETROLux 20/50 and RETROFlex 20–80), in-IGU systems (RETROLuxTherm 12/20 mm for fixed, maintenance-free performance), and roof/daylight systems. Design options include exterior, interior, or sealed inside insulating glass.

Louvers are roll-formed from thin aluminum with high-reflectance PVD surfaces (≈94–98%). Interior/exterior blinds use antistatic mirror surfaces; in practice they need only light cleaning—and can be ultrasonically cleaned every 10–15 years. IGU-integrated systems are sealed from dust and effectively maintenance-free.
