During many years doing research and testing, Vanlong makes the smart glass improve to double-glazing glass which act high performance of energy-saving, Heat and sound insulation. It combined with two or three layers glass with airspace and PDLC Film stick hardly on one surface of the glass.  This Switchable double glazing unit widely use for indoor partitions especially curtain walls. 

Switchable IGU ( Switchable Insulate Glazing Unit) act high performance of energy saving

with Shading coefficient 0.22-0.49  and Heat transfer coefficient 1.4-2.8W(m2.K).  We made the glass perfectly combined PDLC Film function to IGU function.
