I love the way the insulated panels keep my office cool from the afternoon sun. The panel have a cute Kenji Medallion design which looks great in a casual decorated room such as my office and grandchildren room. The panels do allow light to filter through more than other room darkening panels that I have used. The fleece backing is going to be a plus for any window during the winter that has a draft. I am a little concern as to the durability of the fleece backing of panels once they are wash. Will they shrink and be cover with lint balls.
