Not everyone likes to showcase their daily life to the neighbourhood and privacy blinds are an excellent solution.
If you're no exhibitionist and feel safer with window covering blinds that restrict passersby from gazing inside your home, roller blinds are a common privacy solution. If you go for a sheer blind combination with sunscreen blinds or roman blinds then you can enjoy the view when you want with complete privacy when you need.
These blinds do exactly as they suggest. They let no light in when they are drawn giving you complete privacy when you want it. These usually come ready-made and suit your windows if the the sizes are regular.
If you prefer a bit of light filtering then the sunscreen blinds are what you need. These allow a bit of light to seep through without allowing a full view of the room.
These blinds are also great for privacy. They even restrict sunlight from creeping in and can be great for summers. The roman blinds come in a nice pleated pattern which is great if you're looking for a bit of design in the room.
During the day you can use the sheer types in your home and get the light airy effect in the room. At night you can draw out the thick blinds and block out the view of all people.
If you live in a suburban home you will enjoy privacy from walking pedestrians or anyone else.
