The excellent performance of a YewdaleDefiant® cassetted blind is further enhanced by the addition of side channels, holding the fabric in place. These side channels also limit the level of light that enters the room, especially if blackout fabric is used. The entire range is offered as an aesthetically pleasing solution, protecting the fabric in the process. The quality sidewinder mechanisms are simple to operate and allow accurate control of blind position.
