Want to escape prying eyes and harsh sunlight? The black-silver KESPEN film reflects up to 82% of infrared and 90% of ultraviolet rays, keeping your space cool in summer and warm in winter. During the day, it provides a mirror-like privacy shield—outsiders can’t see in, but in the evening, when you turn on the lights, the effect disappears, so curtains are still your best friend! Easy to install—no glue, just water—and just as easy to remove without leaving any residue. Bonus: lower air conditioning costs and protection for furniture from fading. A smart solution for comfort and privacy
