PriWatt® PDLC Glass is composed of a thin film interlayer of liquid crystals dispersed in a polymer matrix (PDLCs) laminated between two low iron glass panels. By applying a small electrical current, its state can change from opaque to transparent and vice versa.

All our glass is processed and finished in-house using LAMIFLEX machines and kilns. Our low iron, premium quality glass has the highest levels of clarity and consistency.

We provide professional customer service from the moment a quote was requested to the final touch of the job completion.

Our Florida-based manufacturing facility allows us to quickly get your glass orders manufactured and shipped out on time. The lead time is 2 to 4 weeks and delivery is 5-10 Days.
