When it comes to defending your home against burglars, window locks

are your first line of defense. A window that doesn’t lock is like an

invitation to burglars, and a lock that isn’t easily visible sends the

same message. Window locks that are easy to see are the best choice
for home security.

Older homes often don’t have window locks at all. They can be
retrofitted with a locking version of the central catch to help make
older windows more secure. For added security, a sash stop can be
added. Using a steel bolt secured by a key, a sash stop ensures that
an intruder cannot force the window open. Even with the sash stop
installed, the window can be left open a few inches for ventilation.

Casement windows are hinged on one side and lock on the other. They
usually include some sort of latch, but the best kind of lock for
these windows are key locking bolts.Louvre windows may be stylish, but the glass panels can easily be slid
out of place by an intruder. To prevent this, use a two part epoxy
resin to fix the glass panels into place. There is also a special
louvre lock available for this type of window.If your home has sliding windows, ensure that the panels cannot be
lifted out of the frame. Most modern sliding windows come standard
with a latch system, but sash stops and clamps may also be added to
secure them to their frame.Awning windows, similar to casement windows, are hinged on one side
and latch on the other, but awning windows swing upward instead of
outward. Special awning security locks may be added to aluminum and
timber frames.Always remember to lock your windows and keep the keys in a safe
place.
