When choosing a rod for your window curtains, you could select either modern tension rods or traditional ones. Traditional rods usually require plenty of drilling, and you need to have the tools to help you install them. It’s also important to remember that you might not be allowed to drill walls if yours is a rented property. Tension rods are much easier to install as they do not require any drilling. Moreover, they are expandable, and you could adjust them to fit the exact measurements of the curtain you wish to hang.
