Self-adhesive PET material: Compared to static cling film, it offers advantages such as long service life, excellent performance, high clarity, and glass breakage prevention

One-way privacy protection: During the day, when outdoor light is stronger than indoor light, the film acts like a mirror, protecting your privacy while allowing sufficient natural light to enter. At night, when indoor light is stronger than outdoor light, the reflection effect weakens; at this time, simply draw the curtains to protect privacy. The mirror effect is related to the intensity of light.

UV and Glare ProtectionThe UV-blocking window film effectively prevents fading of floors, furniture, and curtains. It also shields your eyes and skin from harmful UV rays. Reducing glare while still allowing some visible light to enter creates a comfortable indoor environment.

This thermal control window film reflects infrared rays, reducing heat transfer through the glass. This household window film is an economical way to stay cool in summer and keep warm in winter, helping you save costs by lowering energy expenses. Note: Avoid applying it to double-paned windows exposed to prolonged direct sunlight

To apply it to the glass surface, the protective film on the back must be removed. When peeling off the transparent film, water must be sprayed to prevent the layers from sticking together and getting damaged
