Analysis of the Impact Resistance of Bulletproof Glass: How to Choose the Right Protective Solution for Different Levels
The Structure and Working Principle of Bulletproof Glass
Bulletproof glass is usually composed of multiple layers of glass and special plastic films (such as PVB film). The outer layer of tempered glass is used to resist the initial impact, while the inner layer of plastic film absorbs and disperses the impact force, preventing the glass from breaking.
Advanced bulletproof glass improves impact resistance and shatter resistance by using ultra-high-strength polycarbonate or laminated materials.
Levels and Standards of Bulletproof Glass
The level of bulletproof glass is usually classified according to its impact resistance and the types of ammunition it can withstand. Common standards include:
- UL 752 Standard: Classified according to the bulletproof glass's ability to protect against different firearms, from Level 1 (low-level protection) to Level 8 (high-level protection), where Level 1 can defend against small handguns, while Level 8 can withstand high-powered rifle bullets.
- European EN 1063 Standard: Divided into BR1 to BR7, covering a variety of protection capabilities from handguns to rifle bullets.
How to Choose the Right Protective Solution
- Consider the security needs of the location: For example, high-value locations such as banks and jewelry stores may require Level 4 or higher protection to effectively resist high-powered weapons attacks; while offices or stores can choose Level 1-3 protection, suitable for everyday small threats.
2. Understand common threat types: If the area frequently faces violent conflicts or high-risk factors, when choosing, ensure that the thickness and multi-layer structure of the bulletproof glass are sufficient to withstand possible attacks.
3. Balance between design and aesthetics: Bulletproof glass generally sacrifices a certain degree of transparency and aesthetics, so when choosing, you can consider the requirements of light transmittance, color, and thickness comprehensively, especially for spaces that need to maintain visual transparency (such as exhibition halls, reception halls, etc.).
