Have you heard of glass that switches from transparent to frosted at the push of a button? It's called smart glass — and it's changing how we think about privacy, design and energy efficiency in Swedish homes and offices.
What is Smart Glass?
Smart glass, also known as switchable glass or electric glass, is a type of glass that can change transparency using electricity. In its default state, the glass is frosted and opaque. When you turn on the power, it becomes see-through in under a tenth of a second – with a slight haze mostly visible in angled light.
The Technology: PDLC
The technology is called PDLC — Polymer Dispersed Liquid Crystal. Tiny liquid crystals embedded in a polymer film are laminated between two glass panes. When current is applied, the crystals align and let light through. Without current, they scatter light, making the glass appear frosted.
Smart Glass vs. Frosted Glass
Traditional frosted glass is static — always frosted, never clear. Smart glass gives you both options. With a click, you switch between frosted and transparent.
Where is Smart Glass Used?
Offices & Meeting Rooms
Glass walls that instantly become private during sensitive meetings. No need for blinds — a modern, clean expression that blocks direct view on demand.
Bathrooms & Shower Walls
A glass wall that is transparent when not in use and frosted when you close the door — stylish, hygienic and practical.
Hospitals & Healthcare
Patient privacy without dust-collecting curtains. Already used in ICUs, operating rooms and clinics worldwide.
Retail & Showrooms
Display windows that function as projection surfaces in frosted mode and open up the view to products in transparent mode.
