Window bars are metal or wooden grilles installed on windows to enhance security. They act as a physical barrier, making it more difficult for intruders to enter a building through the windows. Commonly found in homes, businesses, and public buildings, window bars come in various designs and can be customized to fit different window sizes. In addition to security, window bars can also provide safety for children and pets by preventing accidental falls. They are often used in areas where windows are left open for ventilation. However, it's important to ensure that window bars can be easily opened from the inside for emergency escape.
