Pros:

Better Durability: Switchable PDLC glass is more durable than self-adhesive PDLC film because it has two layers of tempered glass on both sides to protect the inner PDLC film from being damaged and scratched.

Better optical quality: Switchable PDLC glass offers better optical quality and clarity compared to self-adhesive PDLC film, which may suffer from distortion or haze due to the adhesive.

Easier installation for professionals: Switchable PDLC glass can be installed more easily than self-adhesive PDLC film for professionals, as it comes in pre-fabricated panels that can be simply attached to the frame.

More energy-efficient: Switchable PDLC glass provides better insulation and noise reduction than self-adhesive smart film, making it more energy-efficient and comfortable.

Cons:

More expensive: Switchable PDLC glass is generally more expensive than self-adhesive PDLC film. Also, it is much heavier than PDLC film, which increases shipping freight.

Requires professional installation: Switchable PDLC glass requires professional installation, which can add to the overall cost of the project.

Not easily removable: Switchable PDLC glass is not easily removable once installed, which can limit flexibility for future modifications or renovations.

Longer lead time: Switchable PDLC glass needs a longer lead time in production(normally needs 7-15 days) and delivery than self-adhesive smart film, which can delay the project schedule.

Ultimately, the choice between these two options will depend on individual needs, preferences, and budget.

Smart glass, or switchable glass as it's also known, is an innovative technology that can transform a plain window into something much more versatile. It consists of two or more sheets with embedded PDLC liquid crystal film and electric current traversing it from side-to-side. When the electricity flows through, the crystals will automatically align which makes the glass go clear, giving you transparency. In the absence of electric current the crystals scatter the light and the glass becomes frosted - giving you privacy on demand!

These smart windows have many applications: meeting rooms, shop windows , office dividers, hospitals, schools and luxury homes all make use of this unique technology.
