Curtains are decorative pieces of fabric used to cover windows, providing both privacy and aesthetic appeal to a room. They come in various materials, including cotton, linen, velvet, and polyester, and can range from lightweight sheers to heavy, insulating drapes. Curtains are available in a wide array of colors, patterns, and styles, allowing homeowners to choose options that complement their interior decor. They can be hung with rods, tracks, or even hooks and often feature additional elements like pleats, grommets, or tiebacks for an added touch of elegance. Beyond their visual role, curtains can also serve practical purposes, such as controlling the amount of sunlight entering a space, reducing noise, and helping to regulate temperature by insulating against heat or cold.
