What it costs
| Project | Published cost |
|---|---|
| Office partition wall, installed smart glass | $2,000 to $7,000 (HomeGuide) [1] |
| 60 sq ft conference room partition, smart film, Los Angeles | $4,500 to $10,500 [3] |
| Smart glass, per sq ft installed | $50 to $150 (HomeAdvisor) [2]; $70 to $150 (HomeGuide) [1] |
| Smart glass, orders over 100 sq ft | as low as $70 to $100 per sq ft [1] |
Bigger orders cost less per square foot, because the controller and setup are spread over more glass [1][3]. If you have several rooms, quote them together.
Film on existing walls, or new glass?
Most offices with glass walls already in place go with smart film. It's applied to the inside of the existing glass, with wiring routed to a power source [3]. That avoids taking out walls and reframing. The LA installer says factory smart glass can cost 2 to 4 times as much as a film retrofit in an existing building [3].
Smart glass makes more sense in a new build-out or when the glass is being replaced anyway. HomeGuide gives it a longer life: 20 to 30 years, against 10 to 20 for film [1].
Controls
Options run from a basic wall switch to remotes, phone apps, and voice control [4]. The LA installer lists commercial automation systems, scheduling, and occupancy sensors at the high end of cost [3]. Electrical parts run $200 to $800 per zone [3]. A zone is one group of panels that switches together, so decide which glass needs to switch on its own.
Which kind for an office
- Standard PDLC goes private when off and if the power fails [4].
- Reverse film stays clear when off and uses power only while private. One maker suggests reverse film for office space, since it has less haze when clear [4].
Power use
Running cost is low. One maker rates its film at under 0.5 watts per square foot [4]. The LA installer estimates $5 to $10 a year to keep 50 sq ft clear through business hours [3].
Projection
When frosted, PDLC film can work as a rear projection screen, according to HomeAdvisor and the LA installer [2][3]. That lets a meeting room wall double as a display. Ask the installer how the film you're quoting performs for projection.
Questions to ask an installer
- Is this film or new glass, and what's the warranty on each part?
- How many zones, and what controls are included?
- Who runs the wiring, and is a licensed electrician doing it [1][3]?
- Do you work after hours or on weekends to avoid disrupting staff?
- Can I see a project you've done in an office?
FAQ
Is smart glass worth it for a small office?
It depends on how often you need privacy. HomeGuide puts one partition wall at $2,000 to $7,000 installed [1]. If a room is used for confidential meetings every day, switchable glass replaces blinds and keeps the open look when the room is free.
Does smart film block sound?
No source we use says smart film reduces noise, so don't count on it. HomeGuide notes some smart glass products can reduce outside noise [1]. Ask the installer for a sound rating if privacy from sound matters.
