In London, the windows of my house overlook a busy street, and in the evening it feels like being in a theater—people can see everything that happens at home. I looked through the options at https://www.tintfit.com/shop/privacy-products and ordered a reflective film with special privacy protection. The effect is simply amazing: light still passes through, but nothing can be seen from the outside now. This has created real comfort, even when working late in the living room. Such products are essential in the UK, where many residential areas are densely built up. In addition, the film has made the room's design more stylish.
