Both the upper and lower sashes of a double hung can slide to allow the window to open. To open the lower sash, simply unlock the sash and slide it upwards. To open the upper sash, unlock your lower sash, and gently lower the upper sash to the desired position.
To lock a double hung window, you must first check the alignment of your locks. Ensure that the upper sash is pushed all the way up and the lower sash is pushed down completely, until fully sealed. This will allow your locks to be secured without any obstructions.
