Why does it lose privacy at night? Is it a defect?
This is NOT a product defect. One-way privacy works only when outside light is brighter than indoors.
At night, indoor lights turn the effect around, so people outside can see inside.
For full night-time privacy, please use curtains or blinds.
How do I pick the correct film width for my window?
Measure your actual window width first. We recommend choosing film width 2-3 inches wider than your window. Film length can be trimmed down, but width cannot be increased after purchase. Too-narrow film will not fully cover your glass.
Where can I use this film? Can it replace curtains?
Apply on the INDOOR SIDE of any smooth, clean glass window — home windows, sliding doors, patio doors, office partitions. Not for textured/frosted glass. For bedrooms, bathrooms, offices.
Pairs with curtains at night; complements, doesn't replace
What if there are bubbles or wrinkles during installation?
Clean glass and spray soapy water for repositioning. Use tape to lift backing corners, do not pull hard to avoid film tears. Two-person installation recommended for large-size film. Squeegee outward and press edges firmly. Tiny bubbles fade in 24-48h
Will the film fall off easily? How strong is the adhesive?
High-quality, weather-resistant adhesive for a lasting hold on any smooth glass. One install — bathroom, balcony, kitchen, office — no peeling through humidity or heat, year after year.
