Sometimes, we get too excited about high-tech gizmos for our windows that we forget the real foundation of window security: the locks and other components that keep the window shut. Various options are available but the list narrows down when you take the type of window into consideration.
Bolt Lock: Similar to that you find in doors, a bolt lock can be effective in keeping intruders away. Usually, these types of window locks are present in sliding casement windows.
Screw: Prevent the window from opening too far with the help of a screw. Simply drive a screw into your window sill just several inches away from the glass pane. The screw will stop the window from opening wider.
Specialised locks: Lock companies are now making locks for specific types of windows. Determine the type of windows that you have and ask somebody from the local home improvement store which type of locks suits your windows best. You may have to hire a professional locksmith to do this.
Key track stop: This simple device can found along your window tracks. Stop the window from moving by turning the key.
Locking pins: Locking pins are usually found on double hung windows. These are remarkably simple security devices; intruders will not be able to lift the sash as one goes through one window sash into the other.
Turnbuckle: Keyed turnbuckle is notable similar to bolt locks for sliding casement windows. You can open the window by inserting a key into the turnbuckle.
Ventilating locks: These types of locks are screwed into the flank of the top sash of a window. These limit the opening. The window can only be moved until it hits the pin if you are going to place the lock an inch above the lower sash. Reposition the pin if you want the window to open all the way.
