Unlike regular glass, which shatters into dangerous shards when broken, impact glass remains intact, preventing injuries and maintaining the structural integrity of a building or vehicle.
Materials used in impact glass
The materials used in the production of impact glass vary depending on the manufacturer and specific requirements. However, the most common materials include two or more layers of glass and an interlayer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) film. These materials are combined using high-pressure and high-temperature processes to create a strong and durable glass product. Additionally, other materials such as ceramic or metal coatings may be added to further enhance the strength and performance of impact glass.
How impact glass is made?
Manufacturing process of impact glass
The manufacturing process of impact glass involves several steps to ensure its strength and durability. First, the glass sheets are cut to the desired size and shape. Then, the interlayer material, typically PVB or EVA film, is placed between the glass layers. The assembled glass and interlayer are then subjected to heat and pressure in an autoclave, a specialized oven, to remove any air bubbles and bond the layers together. This process, called lamination, creates a strong and durable glass product.
Unique features of impact glass
Impact glass possesses unique features that make it an ideal choice for areas prone to extreme weather conditions or high levels of crime. One of its key features is its ability to withstand impact without shattering into dangerous shards. This not only prevents injuries but also provides a barrier against burglars and intruders. Impact glass also offers excellent sound insulation, UV protection, and energy efficiency, making it a versatile and practical choice for both residential and commercial applications.

Is impact glass breakable?
Limits of impact glass strength
While impact glass is highly resistant to forceful impacts, it does have its limits. Under extreme conditions, such as a direct hit by a large object or a powerful explosion, impact glass can break. However, even in such cases, the glass will remain largely intact due to the interlayer material holding the shattered pieces together. This significantly reduces the risk of injuries and allows for prompt replacement or repair.
Factors that can cause impact glass to break
Several factors can contribute to the breakage of impact glass. One such factor is improper installation, which can result in stress points that weaken the glass. Additionally, damage to the glass surface, such as deep scratches or chips, can compromise its strength. It is important to properly maintain and inspect impact glass to ensure its continued performance and to promptly address any issues that may compromise its integrity.
How does impact glass break?
Different types of impact glass breakage
When impact glass breaks, it may exhibit different patterns and forms of breakage. One common type is called spider webbing, where cracks radiate out from the point of impact. Another type is called spalling, where small chips or fragments break off the surface of the glass. These different types of breakage can occur depending on the force, angle, and location of the impact. The specific break pattern can provide valuable information about the nature of the impact and aid in determining the cause of the breakage.
Effect of impact location on break pattern
The location of the impact can also affect the break pattern of impact glass. For example, if the impact occurs close to the edge of the glass, it may result in a more significant and widespread breakage. On the other hand, if the impact is located in the center of the glass, it may cause a smaller, more localized breakage. The location of the impact should be considered when assessing the damage and determining the appropriate repair or replacement method.
