Early Security Measures

• In ancient times, buildings often had small openings or narrow slits for windows, which served both architectural and defensive purposes. These narrow openings made it more difficult for invaders to breach the structure.

19th Century

• As urbanisation increased, there was a growing need for improved security in buildings, particularly in urban areas. This led to the development of more robust window designs and materials.

Early 20th Century

• The early 20th century saw advancements in the manufacturing of materials such as steel. This led to the incorporation of steel frames and bars to reinforce windows, providing an additional layer of security.

Mid-20th Century

• During World War II, there was increased focus on security measures for various types of buildings. This period saw the development of blast-resistant and shatterproof glass for military and critical infrastructure installations.

Late 20th Century

• The late 20th century witnessed a surge in innovations in security technology. This included the development of laminated glass, which consists of multiple layers of glass and plastic interlayers. Laminated glass is resistant to shattering, making it more difficult for intruders to gain access.

21st Century

• Advanced Materials: The 21st century has seen the use of advanced materials in security windows, including polycarbonate, which is known for its strength and impact resistance.
• Ballistic Resistance: Security windows designed to resist ballistic threats have become more prevalent, particularly in high-risk environments such as government buildings and financial institutions.
• Electronic Security Integration: Modern security windows may also incorporate electronic security features, such as sensors and alarms, to enhance overall building security.
• Energy Efficiency: In addition to security considerations, there is an increasing emphasis on energy efficiency in building design. Some security windows are designed to provide both security and energy-saving benefits.

Today, security windows come in various forms to meet specific needs, including laminated glass, bullet-resistant glass, impact-resistant glass, and more. They are used in a wide range of applications, from residential properties to commercial and government buildings.

The evolution of security windows reflects the ongoing efforts to balance architectural aesthetics with the need for enhanced protection and safety in diverse environments. As security threats continue to evolve, so too will the technology and design of security windows to meet these challenges.
