Inside mount shades keep your window trim visible, but leave a light gap of 1/2”-3/4” on both sides of the shade. Your shade will also need at least 1” of depth to keep the shade inside the top of the window frame. Inside mount shades are perfect for rooms that need privacy, but still need to be light and bright.
Outside mount shades cover your window frames, offering superior light blockage and are necessary for windows with casements or other hardware that would normally block the shade from moving up and down. Outside mount shades are perfect for rooms that need protection from the sun or specialty windows.
