Sash locks are attached to the master frame of a given window. Once the window is in a shut situation, the sash lock holds everything in place. Activating the lock means moving both sash parts together, making a seal as a result.
Sash locks, in some ways, are crucial to the very construction of double-hung windows. They prevent the windows from rattling around as a result of almost all vibrations, which would happen with a different lock mechanism in all likelihood. Sash locks can provide excellent security for people who are interested in keeping out intruders as effectively as possible.
Since sash locks manage to pull the sashes together so tightly, these are also the sorts of locks that are going to maintain interior home temperatures very effectively.

Few locks can create a seal as tight as the best sash locks, at least when the sash locks are working at peak efficiency or if they are new.
