Windows, Locks, Keys and Alarms (1)
Windows should be secured so they cannot be lifted from their tracks and if replacing glass consider other materials which are harder to break or penetrate. Louvred windows should be grilled or barred.
If you want to leave windows open, consider installing aesthetically pleasing, solidly constructed aluminium or steel window security grilles. Where security grilles are placed on windows, ensure some grilles are hinged to allow exit in emergencies.You may also care to consider external roller shutters or French shutters that lock internally.
