- What is your goal? Privacy only → PDLC. Also darkening or solar control → combine, or look at SPD/electrochromic glass.
- Existing or new glass? Existing glass → film. New or wet area → laminated glass.
- Mostly open or mostly private? Mostly private → standard PDLC. Mostly open → consider reverse.
- How do you want to control it? Wall switch, remote control, app, voice or home automation (KNX, Zigbee, Home Assistant).
- Where will the transformer go? Preferably accessible (ceiling, utility cupboard, frame) with ventilation.
Ask for these in your quote:
- Brand/manufacturer of the film and the datasheet (haze on/off, light transmission, voltage).
- Maximum panel size and whether there will be seams (film usually comes on rolls about 1.5 m / 5 ft wide).
- Warranty period (film, driver and installation separately) and what it covers (edge discolouration, delamination, dead zones).
- Who makes the mains connection, and whether that is done by a licensed electrician according to local code.
- Finishing of the edges and the cable route.
