General description This one-way mirror privacy window film provides an effective solution for maintaining privacy during the day. The side exposed to the strongest light creates a mirror effect, while the other side remains transparent, allowing visibility outside without being seen. Technical specifications Dimensions: 90 x 199.5 cm Blocks up to 90% of UV rays Blocks 89% of infrared rays Installation Requires a large amount of water to wet both the adhesive surface and the window surface. Once the water dries, the adhesive will regain its viscosity, ensuring a firm hold. Tip: Gradually peel off the backing during adhesion for best results. Usage Ideal for use in homes, offices, kitchens, schools, and any flat, clean, and smooth glass surface. Note: When the interior light is stronger than the exterior light at night, the mirror effect will reverse; it is advisable to close the curtains.
