Switchable smart glass

Switchable smart glass uses a PDLC interlayer between toughened plies so the panel moves between clear and obscured states when power is applied. Busbars, transformers and switching circuits must align with ceiling containment and maintenance access, because the film edge is sensitive to moisture and mechanical damage.

It suits meeting rooms and clinical spaces where blinds would clutter the façade. Double-glazed versions place the switchable laminate as the inner leaf so the outer pane carries thermal performance and weathering while the inner leaf handles privacy control.
