Switch Like Magic with EWT High-Performance PDLC Smart Film
Transform Your Glass at the Press of a Button
Clear View when you want it, Privacy when you need it
EWT switchable smart film is a unique product that lets you switch between clear and frosted effects on your glass windows and partitions with just the press of a button. With EWT smart film, you can control the opacity of any glass window or glass wall with the flick of a switch. This frees you from the use of blinds and curtains for privacy and solar control, while not compromising on large windows, clear views and lighting on demand, essentially opening up your space to infinite possibilities.
Our Smart Film transforms standard glass into intelligent “switchable” glass, allowing you to toggle between transparency and complete privacy in less than 100 milliseconds. We use premium Polymer Dispersed Liquid Crystal (PDLC) technology which operates by controlling the alignment of liquid crystal molecules within a polymer matrix using an electric field.
Our Smart Film acts as a retrofit solution that can be surface-applied to existing single glazing or integrated into laminated glass and double-glazed units.

Our Smart Film is a multi-layer structure engineered for durability and optical clarity, consisting of
ITO Conductive Layers
Ultra-thin transparent coatings on PET substrates that act as electrodes.
PDLC Layer
Micro-sized liquid crystal droplets dispersed in a polymer matrix responsible for the switching capability.
Protective PET Layers
Outer layers ensuring insulation and flexibility
How It Works: The Refractive Principle
EWT offers premium Polymer Dispersed Liquid Crystal (PDLC) Switchable Film. This advanced material operates by controlling the alignment of liquid crystal molecules within a polymer matrix using an electric field.
Privacy MODE (OFF State)
Without power, the liquid crystal droplets are randomly oriented. This mismatch in the refractive index scatters incoming light, creating an opaque, frosted appearance for full privacy.
Transparent Mode (ON State)
When AC power ($65-110$V) is applied, the liquid crystals align parallel to the electric field. The refractive index matches the polymer matrix, allowing light to pass through with minimal scattering.
Integration Options
Our films can be applied to any type of glass
Single Glass
Surface-applied retrofit for existing windows

FAQ
What is the power consumption of Smart Film?
EWT Smart Film is energy efficient, consuming approximately 4 – 6 W per Square Metre when in the transparent (ON) state.
Does Smart Film block heat and UV rays?
es. EWT Smart Film blocks up to 99% of harmful UV rays and reduces Infrared (IR) heat transmission by 30% – 40%, helping to protect interiors and reduce cooling costs in the UAE climate.
How fast does the glass switch from opaque to clear?
The switching speed is near-instantaneous. The film switches states in less than 100 milliseconds, while our laminated smart glass has a response time of < 10 milliseconds from OFF to ON.
Is EWT Smart Glass safe for commercial buildings?
Yes. Our laminated smart glass meets national safety glass standards (GB15763.3-2009). Even if the glass breaks due to external force, the laminated structure ensures personal safety. It also provides sound insulation up to 35dB.
What is the maximum size for a single Smart Glass panel?
We can process customizable sizes with a maximum single-piece dimension of 6000 mm X 2100 mm.
