The double-layer curtain is simply two tracks, and the double-layer effect can be achieved only by installing two tracks, except that one track is used for loading yarn curtains;
The installation of double curtains depends on whether the track of your curtains is the difference between open and concealed. If it is open, you can find a merchant to install it directly. If it is concealed, it is necessary to consider the width of concealed double curtains, which not only ensures the smooth installation of curtains in the later period, but also facilitates the later maintenance and curtain opening and closing.
