Curtains prevent you (and wandering zombies) from seeing in or out of a window. This is very useful while looting a building or sleeping as it prevents zombies from sneaking up on you or being attracted to your location.
While many windows already have curtains, those lacking curtains can have a Sheet added to them by the player (assuming a Sheet is in the players main inventory). This is accomplished by right-clicking on the window and selecting "Add Sheet". After the sheet is added, the makeshift curtain can be open and closed as any other curtain by right clicking and selecting the appropriate action.
Both, residental and sheet curtains can be removed by right-clicking, which adds a sheet to the Players inventory.
