- Measuring: visible glass size minus a small margin (± 2–3 mm), and deciding on which side the busbar and cable will go.
- Cutting to size: the supplier cuts the film, exposes the ITO, fits busbars and cables, and seals the cut edges.
- Cleaning the glass: free of grease, dust and limescale; degrease with isopropyl alcohol.
- Applying: partly remove the liner, align the film and squeegee from the centre outwards (dry installation with OCA adhesive – most PDLC films must not be applied with soapy water).
- Edge finishing: sealant or a profile to keep moisture out and guide the cable.
- Connecting and testing: fit the driver, connect, switch and check the whole surface for dead zones.
Many suppliers only allow installation by their own or certified installers; others also sell DIY kits. See installation for dealer locators worldwide and the installation videos on the videos page. [21]
