A popular alternative to net curtains on terraced houses is to put frost on the bottom half, as we have done with these bay windows. We stripped off some degraded vinyl film which the owners had fitted themselves last year. We fit window film rather than the vinyl film often sold online. Our window film looks better than vinyl, and our film and fitting is guaranteed for 10 years.
We put frost film on these four sliding glass doors to provide total privacy day and night, whilst not reducing the daylight into the room. Having frost means you cannot see in or out. You can however see out with silver film, which we applied to the single window here.
