Frequently Asked Questions

Q: Does the one-way privacy window film work at night?

A: The one-way privacy effect relies on a difference in light levels — it works best during the day when it is brighter outside than inside. At night, when indoor lights are on, the effect reverses and the film becomes less effective at blocking outside views. We recommend pairing it with curtains or blinds for complete nighttime privacy.

Q: Can this reflective window film be removed or repositioned?

A: Yes. The PET-based film can generally be peeled away from glass surfaces. For easiest removal, carefully lift one corner and peel slowly. Clean any residue with a mild glass cleaner. It is not designed for repeated repositioning, so take care to measure and align accurately before final application.

Q: Is this window film suitable for bathroom glass and balcony doors?

A: Absolutely. This film is specifically designed for use on glass surfaces including bathroom windows and balcony glass doors. Its modern reflective finish suits both indoor and outdoor-facing glass, providing privacy and solar protection wherever it is applied.

Q: What sizes and colours are available?

A: The film is available in widths of 40 cm or 50 cm and lengths of 1 m, 2 m, 3 m, or 5 m. Colour options include Diamond Silver, Black Silver, Blue Silver, and Impermeable Black — so you can match your window film to your interior style.
