Curtain rods are long, slender pieces of material, typically made from metal, wood, or plastic, used to hang curtains or drapes. They come in various lengths, styles, and finishes to match different interior designs. Curtain rods can be mounted on walls or ceilings and often feature brackets for support. There are different types of curtain rods, including single rods, double rods, and tension rods. Single rods hold one set of curtains, while double rods allow for layering, such as sheer curtains behind heavier drapes. Tension rods are adjustable and fit snugly between two walls, making them ideal for smaller spaces.
