On our WERU German range of windows and doors we can offer the integrated roller shutter. This shutter is part of the window build up and offers total black out, extra security and shading from the sun. Available in different colours and slat types it is ideal if you work nights or suffer from light pollution. We can also add an insect screen within the shutter box allowing the window to be open and stopping those insects that like to feed on us whilst we sleep from getting in.
