Review on 🪞 Enhance Privacy and Comfort with One Way Mirror Window Film: Daytime Privacy, Heat Control, Anti-UV, Decorative, Non-Adhesive, Suitable for Home and Office, Black Silver, 6 Mil, 17.7 Inch x 6.5 Feet by Denise Miller

This stuff works great. Just remember that as the instructions say, the side of the window that gets the most light is the side that will see in. At night the blinds still have to be closed. Clean your windows really well, buy an installation kit and a good scraper - the one that comes with sucks and you'll end up scratching the film. Be careful when tearing off the backing, crease it will also damage the surface. From the outside, at first glance it looks like a highly reflective window. Inside, incident sunlight is practically not heated. No more sitting in the dark in the summer with your air conditioner on or worrying about the electronics overheating in the sun.
