SpectraNyx Smart Glass and Smart Film both deliver stepless tint control, yet they are integrated into a project in entirely different ways. One becomes part of the glazing structure from the outset; the other gives existing glass a new level of dimming capability.
This distinction may appear simple, but it shapes the glass configuration, installation method, wiring strategy, on-site workload, and final architectural expression.
For new facades, skylights, and architectural windows, SpectraNyx Smart Glass can be planned together with the glazing build-up, control system, and concealed wiring from the design stage.
For retrofit projects, SpectraNyx Smart Film upgrades existing glass in place, reducing removal, replacement, and installation work.
In this article, REACH BUILDING compares product structure, project stage, installation approach, and site conditions to help architects, facade consultants, and contractors identify the most suitable solution for each project.
SpectraNyx Smart Glass and Smart Film are two forms of REACH BUILDING’s SPD-based smart dimming system. Both provide smooth, stepless tint adjustment, allowing glazing to respond to changing daylight, glare, privacy, and visual comfort requirements.
SpectraNyx Smart Glass, also known as smart laminated glass or SPD smart glass, is a dynamic glazing solution based on Suspended Particle Device (SPD) technology. Its light transmission and tint level can be adjusted by varying the applied voltage.
When powered, the suspended particles within the SPD layer align, allowing more light to pass through and making the glass appear brighter and clearer. As the voltage decreases, the particles return to a random arrangement, gradually darkening the glass.
This smooth, stepless tinting allows SpectraNyx Smart Glass to respond to changing sunlight, spatial requirements, and different usage scenarios. It helps manage natural daylight, glare, and visual comfort while creating new design possibilities for facades, skylights, windows, and high-end architectural spaces.

SpectraNyx Smart Film is designed to upgrade existing glazing without replacing the original glass. It operates on the same SPD tinting principle as SpectraNyx Smart Glass but comes in a flexible, self-adhesive format that can be applied directly to installed glass, providing a practical way to add smooth, stepless tint control to existing windows and glazing systems.

SpectraNyx Smart Glass and Smart Film do more than adjust the appearance of glass. Their responsive tint control helps manage solar exposure, indoor comfort, and long-term protection while operating with minimal power.
In practice, these capabilities can translate into obvious advantages for construction projects:
Protection for Interiors: SpectraNyx Smart Glass blocks up to 99.9% of ultraviolet radiation, helping reduce UV-related fading and deterioration of furniture, artwork, flooring, merchandise, and interior finishes.
Improved Solar-Heat Management: SpectraNyx blocks up to 96% of infrared radiation in its darkest state, helping reduce solar heat entering through the glass and supporting a more comfortable indoor environment.
Low-Power Operation: With power consumption of no more than 1 watt per square metre, SpectraNyx provides dynamic tint control with minimal operating energy.
Responsive Tint Adjustment: The glass can brighten in up to 2 seconds and return to its darker state in up to 9 seconds, allowing the glazing to respond quickly to changing sunlight and user needs.
Built for Long-Term Use: Designed for more than one million switching cycles and operation from −30°C to 90°C, SpectraNyx supports stable daily use across a wide range of architectural environments.
Consistent Visual Appearance: SpectraNyx delivers a smooth, uniform tint across the entire glass surface, avoiding the patchy appearance or noticeable colour variation that can affect overall design quality.

Although both solutions use the same SPD tinting technology, they follow different project paths. Choosing between Smart Glass and Smart Film will affect initial investment, transportation, on-site installation, system coordination, and long-term maintenance. The comparison below highlights these practical differences.
For projects that already require new or replacement glazing, such as curtain walls, skylights, architectural windows, and glass partitions, SpectraNyx Smart Glass combines the glass structure and SPD tinting layer in a complete finished unit, with wiring provisions and connection points planned before production.

Before production, REACH BUILDING can configure the panel dimensions, glass build-up, tinting zones, connection points, and control system according to the project drawings. Once delivered to the site, the finished units can be installed using standard architectural glazing methods, with less on-site assembly and secondary processing required.
Because the SPD layer is sealed between two panes of glass, the functional material is protected from cleaning tools, sharp objects, direct contact, and external conditions. Routine maintenance is limited mainly to the exposed glass surfaces, while the finished installation maintains the appearance of an integrated architectural glazing system.
SpectraNyx Smart Glass is easy to clean and maintain.
This solution includes the glass substrates, lamination, system integration, and transportation of the finished units. It therefore requires a higher initial investment and more careful shipping arrangements, but provides a more complete product and allows key design details to be coordinated before installation.
SpectraNyx Smart Film is designed for projects where the existing glazing remains in good condition and does not need to be replaced. Its flexible format allows SPD tint control to be added directly to installed glass while retaining the original panels and framing, making it well suited to retrofit applications such as existing windows, office partitions, storefronts, and commercial spaces.

The film can be transported in rolls and does not require the purchase or fabrication of new glass panels. The existing glass and framing can remain in place, while on-site work is mainly limited to surface preparation, film application, wiring, edge protection, and control-system commissioning. This helps reduce demolition, transportation, glass replacement, reinstallation, and building-restoration work.

SpectraNyx Smart Film is supplied in rolls for easier handling, safer transportation, and more efficient on-site installation.
Because the film is applied directly on site, installation quality depends on proper surface preparation, accurate positioning, and careful edge treatment. REACH BUILDING can provide professional installation guidance and technical support to help ensure that each stage is completed correctly.

As the film remains on the exposed glass surface, appropriate cleaning and routine care are also important. REACH BUILDING provides maintenance guidance to help protect the film from scratching, prevent damage to the edges, and support reliable long-term performance.

Across both formats, SpectraNyx supports stepless tint adjustment and flexible control for single panels, grouped zones, or larger glazing systems. REACH BUILDING can configure four main control options according to the project: a compact USB controller, wireless remote control, an LCD touch display, or smart home integration.

For more automated projects, SpectraNyx can be connected to light sensors, scheduled scenes, or a BMS. When outdoor sunlight becomes intense, the system can automatically deepen the tint to reduce glare and solar heat gain. Under softer or overcast conditions, it can return the glass to a lighter state to maintain natural daylight and exterior views.

REACH BUILDING can also assist with controller selection, connection positioning, and concealed wiring planning based on the project drawings. Each glass panel requires only two reserved connection points, which can be positioned to suit the glazing design.
