Smart film
Goes on the glass you already have
A thin adhesive layer applied to existing windows, doors and partitions. It's cheaper and faster, but it doesn't last as long as glass. HomeGuide puts smart film at 10 to 20 years [2].

How it works
No blinds. No curtains. Just a quiet layer of liquid crystal.
Most switchable privacy glass uses PDLC, a liquid crystal layer inside a thin film. Power on, the crystals line up and the glass is clear. Power off, they scatter the light and the glass looks frosted. It works the same whether the film is stuck onto glass you already own or sealed inside a new panel.
- It fails private. If the power goes out, standard PDLC film goes frosted, according to Smart Glass Tech US [5].
- It goes fully opaque. HomeAdvisor says PDLC is the only type of smart glass that does [1].
- It stays bright. Frosted glass hides the room but keeps most of the daylight [3].
- You pick the control. Wall switch, remote, phone app, or Alexa and Google Home [5].
Power off. Crystals scatter the light. Frosted.Power on. Crystals line up. Clear.
What it costs
Real numbers, and who published them.
These are published ranges, not local bids. Sources disagree, so we show who says what. The only number that matters in the end is the quote for your glass.
| Option | Published range | Who says so |
|---|---|---|
| Smart film, material only | $30 to $45 per sq ft | HomeAdvisor [1] |
| Smart film, material only | $37 to $69 per sq ft | Smart Glass Country, a maker [3] |
| Smart film, installed with wiring | $75 to $175 per sq ft | Rapid Window Tinting, a Los Angeles installer [4] |
| Smart glass, installed | $50 to $150 per sq ft | HomeAdvisor, which puts the average at $100 [1] |
| Smart glass, installed | $70 to $150 per sq ft | HomeGuide [2] |
Why is film cheap on paper and pricier installed? The low numbers are for the film alone. The Los Angeles figure includes labor, the transformer, wiring and the switch [4]. Small jobs also cost more per square foot, because that setup costs about the same for one window as for ten [2][4]. For comparison, HomeAdvisor puts motorized smart blinds at about $500 per window [1].

Film or glass?
Two ways to get the same magic trick.
Smart glass
A new panel with the film sealed inside
It costs more and means replacing the glass, but the film is better protected [2][4]. HomeGuide puts smart glass at 20 to 30 years [2].

An installer who does good work will answer every one of these without flinching. More questions are in our installation guide.
- Get at least two quotes on the same glass area and control setup.
- Ask whether the price includes the transformer, wiring, and switch or app control.
- Ask if a licensed electrician will do any new wiring [2][4].
- Compare the film's warranty length. One maker offers 3 years on standard film and up to 7 on premium [3].
- Check the installer's license and insurance yourself.
