Cleaning, maintenance and troubleshooting
How to protect the installed system and diagnose problems sensibly.
How do you clean smart film?
Direct answer: Use the cleaning method supplied for the selected film: normally a soft non-abrasive cloth and an approved mild cleaner, with liquid controlled away from edges and electrical connections. Do not assume every glass chemical is film-safe.
Can I use normal glass cleaner on smart film?
Direct answer: Only if the product guidance permits it. Avoid abrasive pads, blades, aggressive solvents, ammonia or other chemicals not approved for the surface, and do not flood exposed edges.
Does smart film need regular servicing?
Direct answer: The film has no moving parts, but the installed system benefits from visual checks of edges, leads, controls and transformer access, particularly in demanding commercial or wet environments.
How long does smart film last?
Direct answer: Service life depends on the film, installation, electrical design, switching pattern, temperature, solar exposure, humidity, edge protection and cleaning. Use the current product and warranty information rather than a universal lifespan claim.
Why do bubbles appear under smart film?
Direct answer: Possible causes include contamination, poor glass preparation, application error, moisture, substrate defects or later edge failure. Small visual marks and true adhesion failures are not diagnosed the same way; send clear photos and project details.
Why is smart film lifting at the edge?
Direct answer: Edge lifting can relate to contamination, moisture, unsuitable sealant, movement, damaged film, poor clearance or environmental exposure. Stop using unapproved cleaners or sealants and contact the support route for diagnosis.
What should I do if the film stops switching?
Direct answer: Record which panes or zones are affected and whether the issue is constant or intermittent. Check only user-safe controls and isolation; then contact support because the cause could be power, transformer, control, connection or film.
Why does only part of a pane turn clear?
Direct answer: Partial switching can indicate a connection, conductive-layer, busbar, power or film issue. Do not increase voltage or alter the transformer; isolate if advised and send a video showing the whole pane and control action.
Can scratched smart film be polished?
Direct answer: Usually not like ordinary glass. Abrasive polishing can worsen the surface. Ask whether the mark is superficial, whether a protective layer is involved and whether panel replacement is the appropriate remedy.
Can smart film be repaired on site?
Direct answer: Some connection or control faults may be repairable, while damage to the active film area can require replacement. Diagnosis should separate film, application and electrical causes before work is authorised.
What information is needed for a warranty or support claim?
Direct answer: Provide order or project reference, installation date, installer, affected pane, symptoms, photos or video, switching conditions, cleaning history and any recent building or electrical work. Coverage depends on the written terms for the supplied system.
Does PriviFilm have a 10-year warranty?
Direct answer: Where the quoted PriviFilm system includes the manufacturer’s 10-year warranty, eligibility remains subject to the specified product, approved installation, electrical design, care and the written terms supplied with the project. Check the actual quotation rather than relying on a generic site statement.
