The installation is done without drilling and fastening screws in the window frame, so the side-pull double roller blind is also suitable for plastic window frames. Both the sizes and the colors can be selected from a wide range of variations. In addition to the decorative values, the double roller blind also has very useful properties. Through two parallel running fabric panels can be individually adjusted, how far views from the outside are possible. Between light transparency up to the complete view, protection can be regulated steplessly.
