A flexible polymer-based film (typically PDLC: Polymer Dispersed Liquid Crystal) with an adhesive layer on one side. It is applied directly to existing glass surfaces like a sticker. A laminated glass unit where PDLC film is permanently sandwiched between two layers of glass using EVA or PVB interlayers under high pressure/temperature. This creates a solid, structural glazing product. • Optical Clarity: • Energy Efficiency: • Durability: • Safety: • Film: Ideal for retrofitting offices, shower doors, storefronts, or rental properties. • Glass: Suited for high-end architectural projects (facades, security rooms, partitions), automotive sunroofs, and aviation. Choose self-adhesive smart film for cost-effective, non-invasive upgrades to existing glass. Opt for smart glass in new builds or high-traffic areas demanding durability and safety. Both deliver dynamic privacy/energy savings but cater to different project scales and budgets.1. What is self-adhesive smart film and smart glass
Self-Adhesive Smart Film:
Smart Glass:
2. Installation & Application
Feature
Self-Adhesive Smart Film
Smart Glass
Installation
Peel-and-stick onto existing glass; DIY-friendly.
Requires professional glazing; replaces entire glass unit.
Best For
Retrofitting existing windows/glass partitions.
New constructions or full renovations.
Complexity
Some skill is needed:
1. How to install the film;
2. How to deal with the edge sealant;
3. How to hide the wire.
Install the glass as the normal glass except for considering how to hide the wire.
How to make smart glass?
3. Functionality & Performance
Both switch between transparent (ON) and opaque (OFF) via electricity. Smart Glass often has higher clarity due to glass encapsulation.
Identical function: Blocks ~99% UV rays and reduces heat gain.
Power consumption is low (~5W/m²/hour).
Smart Glass is more robust (scratch resistant, impact-resistant, safety-glass properties, longer life time). Film is vulnerable to peeling/scratches comparing with smart glass.
Smart glass remains secure after breaking. Film lacks structural security but can prevent glass from shattering.

5. Pros vs. Cons Summary
Type
✅ Pros
❌ Cons
Self-Adhesive Film
Affordable, easy install, UV/heat blocking, retrofit-friendly
Less durable, no structural safety, prone to air bubbles, Lower clarity than smart glass.
Smart Glass
Premium finish, enhanced safety/durability, seamless integration, higher clarity and performance than film.
High cost, inflexible for existing spaces, complex replacement.
Conclusion
Smart glass works via electrical signal through activation of switches, sensors etc. Liquid crystal molecules turn to allow light to pass through and glass becomes transparent. It is opaque when not activated.
Warranty period is 2 years from date of installation. The life time of the film/glass is up to 10 years depends on varies working environment.
When not connected to a voltage, typically the transmittance can be as low as 2%. When connected to a voltage, it can be up to 80%, but this maximum value varies from manufacturer to manufacturer.
Yes, smart glass/film is a rear projector screen with wide viewing angles. Even from the side one can enjoy clear, beautiful images and also in bright locations with high functional projectors.
With no applied voltage, the liquid crystals are randomly oriented and scatter the light which enters. When an electrical signal is applied, the liquid crystals orient themselves parallel to each other, allowing light through.
