Are there One Way See Through Dimout Fabric where you can see out but no one can see in?

　　Voile Roller Blinds are the modern version of a net curtain.

　　During the day they allow light to filter through whilst offering some privacy in your room.

　　The View From Outside During The Day

　　From outside they do offer privacy due to the fact that the light outside is much brighter than the light inside.

　　As you can see from the picture the person in the room can not be seen.

　　However you can notice the items on the sill due to their close proximity to the blind.

　　This makes them a very popular option due to their contemporary looks.

　　Do always bear in mind this varies according to fabric type and opacity. Also the location of the observer and the lighting inside can make a difference.

　　The View From Outside At Night

　　At night they are not as effective when the lights are on in the room.

　　This is due to the stronger light being inside the room and so the perceived one way properties are reversed.

　　This is due to the placement of the lighting in the room and its reflection of the person within.

　　As a result we often recommend mounting voile roller blinds in the recess near the window.

　　Placing a Roman Blind in front is great for use at night.

　　Quad Screen Fabrics

　　Its due to their one way properties that screen fabrics are very popular in offices

　　They filter out some of the strong light and provide privacy.

　　Available in 4 different openness factors that can be selected according to the aspect of the window.

　　So in a south facing window you would require a tighter weave to absorb more heat from the sun.

　　In office use it genrally is not an issue that the privacy feature is lost at night as the office may not be manned.

　　When the fabric is aligned there are transparent stripes interspaced with dim out stripes. This is great to allow light in during the day

　　The alignment can be adjusted so that the dim out stripes overlap ensuring that you have privacy within the room.

　　As you can see from the examples below this gives excellent flexability.

　　The fabric colour also makes a great deal of difference as darker fabrics absorb more light and lighter fabrics absorb less.
