What aspect is critical when choosing glazing material for security purposes?

When selecting glazing materials for security purposes, the resistance to burglary is the most critical aspect. This is because the primary function of security glazing is to prevent unauthorized access and protect against break-ins. Materials that are specifically designed for security often have features like increased thickness, laminated layers, or special coatings that enhance their strength and resilience against impacts. This makes them more capable of withstanding attempts at forced entry, such as those from tools used by intruders.

While cost-effectiveness, color and design, and availability are important factors in overall project planning and aesthetics, they are secondary considerations when it comes to the fundamental purpose of security glazing. The primary goal is to create a barrier that is hard to penetrate, which directly addresses the need for protection against burglary. Therefore, prioritizing resistance to burglary ensures that the chosen glazing material effectively fulfills its security role.
