Perfect Fit Shutters Lite by Louvolite 

Perfect Fit Shutters are the ideal product for a smart and finished look, without the need for any drilling or screwing. These blinds fit directly to your window meaning they move with the door or window, allowing full operation without any hindrance. (therefore making them suitable for inward opening windows, french and patio doors). You also have full control over privacy and light with the ability to tilt the shutter louvres to any angle, giving you piece of mind. 

The shutters, which come with a 10 year life guarantee, are waterproof so they can be wiped clean, as well as the blind itself being easily removable for decorating and cleaning.
