A screen (10) or fencing structure which provides one-way viewing characteristics under conditions of substantially equal lighting on each side of the structure is described. The structure has a fabric which has a light transmission of about 2.8% to about 25%. The first side (12) of the structure has an overall light reflectance to light transmission ratio of greater or equal to about 2.5,. and the opposite side (14) of the structure has an overall light reflectance to light transmission ratio of less than or equal to about 2. Fabrics that can be used to make screen are also described. |
