There are several different types of curtain rods that can be used to hang curtains. Perhaps the most well known type of curtain rods are the spring-rods, which are also called spring tension-rods or simply tension-rods. Spring-rods are the easiest of all types of curtain rods to install, and installation does not require any special type of hardware. This is because these curtain rods are capable of holding themselves up through the use of a spring that pushes the ends of the rods outward. As such, spring-rods mount directly to the sill of the window or to the molding or trim around it.

Magnetic rods are more decorative curtain rods, yet they are still quite simple to install. Like spring-rods, magnetic rods hold themselves in place. Rather than using a spring, these curtain rods make use of a magnet. These curtain rods are more expensive than spring-rods and require a metal windowsill in order to work. Some homeowners who do not have a metal windowsill choose to glue magnetic rods in place instead.

Sash-rods are a third style of curtain rods. Sash-rods are thinner than other types of curtain rods and are also quite decorative. These curtain rods are intended to be placed slightly above the top of the window, and the curtain should hang slightly below the bottom. For this reason, homeowners choosing to use these curtain rods must purchase a curtain that is longer than the actual window.

Another option are café sash-rods. These curtain rods are similar to sash-rods, but larger in circumference. In addition, they are intended to stick out from the wall slightly, rather than lying flat against the surface like sash-rods. Like sash-rods, these curtain rods are meant to be used with curtains that start slightly above the window and end slightly below it.

Curtain rods are also available in a variety of colors, though the most common colors for curtain rods are brass finish, white, and ivory. In addition, curtain rods can be made from wood, vinyl, or metal. The type of material used to create curtain rods does not necessarily indicate its quality. Rather, craftsmanship plays a large role in the durability and attractiveness of curtain rods.
