Introduction
The strongest type of glass is tempered laminated glass, which combines the toughness of tempered glass with the security benefits of laminated glass. It is used in applications requiring maximum impact and break-in resistance, such as security glazing, banks, and high-risk buildings.
This article provides a detailed overview of the strongest glass options available and how to choose the best one based on specific needs.
The strongest types of glass
Tempered glass: enhanced impact resistance
Tempered glass is manufactured through a process of heating to extremely high temperatures, followed by rapid cooling. This treatment alters the internal structure of the glass, making it up to five times stronger than regular glass.
This type of glass is widely used for glass doors, shower enclosures, building facades, and partitions. If it breaks, it shatters into small, blunt fragments, reducing the risk of injury.
Best suited for environments with high mechanical stress.
Laminated glass: protection against break-ins
Laminated glass consists of multiple layers of glass bonded together with an interlayer, typically polyvinyl butyral (PVB). This structure gives it high resistance to impacts and attempted break-ins.
When broken, the glass fragments remain stuck to the interlayer, preventing them from scattering and offering increased protection against injuries. Laminated glass is also known for its effective sound insulation and ability to block a significant amount of UV rays.
Best suited for security windows, storefronts, and balustrades.
Tempered laminated glass: the ultimate solution
Tempered laminated glass is a hybrid type that combines the benefits of both tempered and laminated glass. It consists of sheets of tempered glass bonded with PVB interlayers. This combination provides impact resistance up to eight times higher than standard glass.
Best suited for anti-theft glazing, buildings exposed to extreme weather conditions, and installations requiring high impact resistance.
Other highly resistant glass types
- Wired glass contains an integrated metal mesh, increasing its resistance to impacts and limiting fragmentation upon breakage. It is often used in industrial and fire-resistant applications.
- Polycarbonate glass, used for bulletproof windows, offers exceptional impact resistance thanks to its flexible, shatterproof polymer structure.
- Borosilicate glass, known for its high thermal resistance, is used in industrial environments exposed to extreme temperatures.
Comparing glass performance
If you are looking for glass that is difficult to break, opt for tempered glass. For anti-theft protection, choose laminated glass. If you need the most resistant glass on the market, go for tempered laminated glass.
The choice depends on the intended use:
- Protection against accidental impacts: tempered glass.
- Protection against break-ins and vandalism: laminated glass.
- Maximum resistance to impacts and mechanical stress: tempered laminated glass.
How to further strengthen glass resistance?
Even the strongest glass can benefit from additional reinforcement to enhance its durability and security.
Applying security window films
Security films for windows are an effective and affordable solution to increase impact resistance without replacing existing glazing. These transparent films allow for:
- Holding glass fragments together in case of breakage.
- Increasing resistance against break-in attempts.
- Enhancing protection against accidental impacts.
A great alternative for buildings that need reinforced security without changing their glass.
Choosing the right glass for the environment
The orientation of the building and its exposure to risks should be considered when selecting glass. For example:
- A building exposed to storms and thermal shocks will benefit more from tempered laminated glass.
- A storefront or display window will require laminated glass to protect against break-ins.
- Hospitals and public spaces can opt for tempered glass to ensure user safety.
FAQ: Common questions answered
Does unbreakable glass exist?
No, no glass is entirely unbreakable, but certain types, such as polycarbonate glass, are extremely resistant and designed to absorb very high impacts.
What type of glass is used for bulletproof windows?
Bulletproof glass consists of multi-layer laminated glass combined with polycarbonate to absorb projectile impact.
What type of glass is used in cars?
Windshields are made of laminated glass, while side and rear windows are often tempered glass to ensure better safety in case of an accident.
Conclusion
Tempered laminated glass is the strongest option, offering both security and durability. However, the best choice depends on the intended application: tempered glass for mechanical impacts, laminated glass for security, and tempered laminated glass for maximum resistance.
To further reinforce glazing, applying security window films is an effective and cost-efficient solution.
