What is smart glass?
Smart glass is glass that electrically changes its optical properties. When low voltage is applied, it becomes transparent. When the current is cut, it turns frosted and blocks visibility. The result is dynamic privacy that replaces blinds, curtains and permanently frosted glass.
There are several technologies behind smart glass: PDLC, SPD and electrochromic glass. PDLC is the most common and cost-effective on the Swedish market, and the one we specialise in. Glasnova supplies PDLC exclusively as a self-adhesive smart film that mounts on your existing glass – no pane replacement needed.

How smart glass works – step by step
1. Voltage controls
A transformer converts 230 V to 60 V AC powering the smart glass layer. When on, millions of liquid crystals align and light passes straight through – the glass is clear.
2. Off = frosted
When power is cut, crystals scatter and refract light in every direction. The glass turns milky white, completely blocking visibility while still letting in daylight.
3. 0.1 seconds
Transition happens in under 0.1 s. Control via switch, app, remote or integrate with smart home systems like KNX, Loxone and Apple Home.

Smart glass vs blinds and curtains
Many ask why to choose smart glass over traditional blinds. Here are the key differences:
| Smart Glas | Blinds | Permanent frosted glass | |
|---|---|---|---|
| Switch clear/frosted | 0,1 s | Manual | Never |
| Maintenance | None | Dust, repair | None |
| Hygiene (clinic/spa) | Excellent | Poor | Good |
| Modern design | ★★★★★ | ★★ | ★★★ |
| Smart home control | Yes (KNX, app) | Limited | No |
| Heat insulation | Contributes | Marginal | Marginal |

FAQ about smart glass
Smart glass in detail – everything before you buy
Types of smart glass
Three main types of smart glass exist: PDLC, SPD and electrochromic. PDLC dominates because it switches instantly, costs least per m² and can be installed as self-adhesive film on existing windows.
For fast installation, low investment and best parts supply, PDLC smart film is the obvious choice. Glasnova supplies PDLC only as a self-adhesive smart film – no pane replacement and fully reversible.
How to choose the right smart glass
Three factors decide which smart film fits: surface to cover, control type and budget. Self-adhesive PDLC film works on virtually any flat glass surface and installs dust-free in 1–2 days without replacing the pane.
Also think about controls. Simplest is a wall switch. For smart home integration use a wifi relay for app, Apple Home, Google Home or KNX. Offices with many zones use scene control.
Smart glass market in Sweden
Smart glass adoption in Sweden has grown sharply. Drivers include modern offices/homes with large glazing, and rising awareness of privacy and light control. Consultancies, medical clinics, law firms and design hotels increasingly pick smart glass over blinds.
In private homes, common uses are bathrooms, bedrooms with neighbour exposure, balcony doors and kitchen islands. Inner-city Stockholm has highest demand due to dense neighbours and architecture incompatible with curtains.
Energy savings with smart glass
Smart glass aids energy efficiency: it lets daylight in (55% transmission even when frosted) reducing artificial lighting, and adds insulation. In commercial buildings smart glass with daylight control can cut lighting costs by up to 30%.
Common mistakes when buying smart glass
- Picking cheapest film without checking specs. Low-quality PDLC can have visible grids, uneven frosting or 2–3 year lifespan.
- Forgetting the transformer. The film needs a specific 60 V AC transformer – plain 230 V destroys the layer instantly.
- DIY install in a dusty room. Particles under the film show forever once it switches. Install needs a clean environment.
- Undersizing the electrical install. Too many m² on one transformer causes low voltage and weak switching.
