Locks For Double Hung Windows:
Even though they are extremely popular, double-hung windows just aren’t terribly secure. Making them secure isn’t complicated or expensive, and all but one of the methods listed here allow you to keep the window partially open.
Right:
One way to secure double-hung windows is to install an inexpensive lag-screw system. Pre-drill the sashes and insert the screws through recessed washers. Tighten the screws with a special key provided with the hardware. Make sure the screws don’t go clear through the upper sash-they’ll let in outside air. Another hole or two on the upper sash lets you lock the window in partly open positions for ventilation.

Here’s an even easier way to protect double hung windows. With this method, you don’t have to purchase any special hardware.

A bolt action, keyed lock also strengthens double-hung windows. Install it on the top rail of the bottom sash, flush to one side of the upper sash. Keep the key near enough for quick emergency exits, but out of reach of a prowler’s exploring hand. To secure windows in an open position and provide ventilation, install additional brackets on the upper sash.
