Broad application One-way transparent privacy window film for day and night use on smooth, clean glass. Ideal for bedrooms, living rooms, kitchens, offices, and anywhere you want privacy without sacrificing light. Thermal and light control The film includes a special thermal control layer that helps block part of summer heat and reduce winter heat loss, helping you feel cool and comfortable indoors. Privacy protection Anti-privacy coating provides a strong privacy effect. The reflective surface is visible from the outside during the day, while people outside cannot clearly see the interior, protecting your privacy and security. UV reduction Blocks UV rays and glare while still allowing natural light to enter. This helps prevent skin aging and fading of furniture, contributing to a comfortable, healthier home and office environment. Use scenarios - In bedrooms or living rooms, enjoy daylight while maintaining daytime privacy. - In offices or glass-partitioned work areas, preserve privacy for calls and meetings without sacrificing natural light. - In kitchens or other frequently used glass surfaces, reduce glare and UV exposure while keeping the room bright.
