There’s little reason not to use blinds or curtains with your casement windows, as it does not interfere with the normal function of the material. The outward opening movement of casement windows means that anything can be placed on the inside, giving it a great deal of space-saving qualities on top of what it already offers. The choice between curtains and blinds depends on your personal preference, the style of your home, and the room’s functionality.  For a classic, elegant look in your living room or bedroom, you might opt for curtains, which can offer an array of fabric choices and designs. On the other hand, blinds can provide excellent control over light levels, which is ideal for those bright summer days – perhaps better suited for rooms where too much light can interfere with its function (such as a dining room). You could even consider Roman or roller blinds for a clean and modern look.
