Commercial façades
Manage changing sun exposure across selected façade zones.
Electrochromic glass changes tint electronically to help manage glare, solar heat and visual comfort while preserving the connection to the outside. SEG supports product selection, glazing coordination, controls and project planning for premium façades, skylights and architectural interiors across the UAE and GCC.
Electrochromic glass is dynamic glazing that changes its visible tint when a low electrical control signal is applied. Unlike PDLC privacy glass, it normally remains see-through while becoming lighter or darker. Its main role is to manage daylight, glare and solar heat rather than create an opaque privacy screen.
The final appearance and performance depend on the selected product, glass build-up, façade orientation, panel size, control system and project conditions. These items should be reviewed before the glass specification is finalized.
Light tint stateDark tint stateElectrochromic technology should be planned as part of the glass, façade, electrical and automation package, not as a surface film added after installation.
The controller applies a low electrical signal to the active electrochromic layers.
The glass progressively changes its light transmission to the selected tint state.
Darker tint helps manage glare and solar exposure while the exterior view remains visible.
Manual commands, schedules or sensors can request a lighter or different approved state.
Best suited to projects where façade orientation, occupant comfort and building controls can be coordinated early.
Manage changing sun exposure across selected façade zones.
Support visual comfort around large windows without permanent blinds.
Create adaptable daylight conditions in premium guest spaces.
Help reduce screen glare and discomfort near glazed elevations.
Support controlled daylight in selected patient and clinical areas.
Address strong overhead sun where fixed shading may be difficult.
Change tint as exterior light conditions and space requirements change.
Support occupant comfort in bright spaces and near digital displays.
Keep a view through the glass in lighter and darker tint states.
Reduce dependence on visible blinds in appropriate applications.
Plan different façade zones around orientation and exposure.
Coordinate with compatible sensors, schedules and automation systems.
Electrochromic glass is a designed glazing system. Early coordination avoids incorrect expectations about colour, switching behavior, wiring and façade performance.
Review solar exposure by elevation, season and time of day.
Confirm safety, thermal, structural, optical and acoustic requirements.
Define which panes operate together and how zones respond.
Coordinate concealed wiring, controllers, access and maintenance.
Confirm interfaces between glass, façade, electrical and BMS teams.
Availability depends on the selected electrochromic system and approved control architecture.
Request approved tint states from a local control point.
Coordinate tint changes around known occupancy or solar patterns.
Use compatible daylight or solar sensors as part of the control logic.
Connect approved interfaces to a wider building-management strategy.
Define comfort, daylight, appearance and control objectives.
Review product, glass build-up, sizes and required performance.
Align façade, electrical, controls, wiring and access requirements.
Manufacture approved glass units to the confirmed project schedule.
Install, connect and verify approved tint and control behavior.
Send your elevations, glazing sizes, façade orientation and control requirements for an initial technical review.
It is primarily designed to remain see-through while changing tint. It should not be specified as a direct substitute for frosted PDLC privacy glass.
Tint transition is progressive. Actual switching behavior depends on the selected system, glass size, temperature and product design.
It can support solar heat and glare-management objectives. Project performance must be confirmed from the approved glass build-up and manufacturer data.
Compatible systems may support sensors, schedules or BMS integration. Interfaces and responsibility must be coordinated during design.
It is generally supplied as a purpose-designed glazing unit rather than a simple adhesive retrofit film. Existing conditions require technical review.
Panels can be planned in control zones depending on the selected system. Zoning should follow façade exposure and operational needs.
