Handles and locks are what you touch and what secures the window. Here's a plain look at the options.
uPVC windows use sturdy handles that operate the locking mechanism. Lockable handles add a key for extra security, useful on ground-floor and accessible windows.
Behind the handle, a multi-point mechanism (often espagnolette-style) engages locking points along the sash. This is what both secures the window and pulls it tight against the gasket.
Ground-floor and accessible windows benefit from lockable handles. Upper floors can use standard handles. The mechanism behind matters as much as the handle itself — both should suit the window's exposure.
