Laminated Glass in Transportation Vehicles: Safety and Comfort


Transportation vehicles have become an integral part of our daily lives, ferrying us from one place to another with utmost convenience. When it comes to ensuring the safety and comfort of passengers, manufacturers have introduced various technological advancements. One such breakthrough is the use of laminated glass in transportation vehicles, which offers enhanced safety features and increased passenger comfort. In this article, we delve deeper into the world of laminated glass, exploring its benefits, applications, and impact on the transportation industry.

Enhanced Safety Measures:

Understanding Laminated Glass

Laminated glass, also known as safety glass, is a specialized type of glass comprising layers of polyvinyl butyral (PVB) sandwiched between two or more glass sheets. The glass and PVB layers are bonded together using high heat and pressure, creating a single, sturdy unit. This manufacturing process empowers laminated glass with unique properties that set it apart from conventional glass.

Protection Against Shattering

Laminated glass offers an excellent safety measure in transportation vehicles by preventing shattering upon strong impact. Unlike regular glass, which can break into sharp shards, laminated glass tends to remain intact even when shattered. This is mainly due to the PVB interlayer holding the broken pieces together, reducing the risk of injuries from flying glass fragments during accidents or incidents of vandalism.

Resistance to External Forces

The inherent flexibility of laminated glass allows it to withstand external forces, making it a preferred option for transportation vehicles. Whether it's a sudden jolt, heavy vibrations, or extreme weather conditions, laminated glass ensures durability, minimizing the risk of cracks or fractures. This resistance to external forces not only contributes to passenger safety but also helps in reducing maintenance costs for vehicle owners.

Improved Comfort:

Noise Reduction

Transportation vehicles often traverse busy streets or highways, generating high levels of noise. Laminated glass acts as an effective noise barrier, reducing the transmission of external sounds into the vehicle cabin. This feature helps create a quieter and more comfortable environment for passengers, allowing them to enjoy a peaceful journey, especially on long-haul trips.

UV Protection and Temperature Control

Another significant advantage of laminated glass is its ability to block harmful ultraviolet (UV) rays. Due to the PVB interlayer, laminated glass can block up to 99% of UV rays, offering protection to passengers from sunburn and potential long-term health issues. Additionally, laminated glass also helps in controlling the temperature within the vehicle cabin by reducing heat transfer. This feature eliminates the need for excessive air conditioning, leading to improved fuel efficiency and reduced environmental impact.

Applications in Transportation:


Laminated glass has found widespread use in automobiles, including cars, SUVs, and buses. It is primarily employed in windshields, side windows, and rear windows. The use of laminated glass in windshields ensures enhanced safety during collisions by preventing occupants from being ejected from the cabin. Additionally, the reduced risk of shattering contributes to improved passenger safety during accidents.

Trains and Trams

Trains and trams often operate in urban areas, where noise pollution is a significant concern. Laminated glass helps reduce noise levels inside these vehicles, enhancing the overall passenger experience. Furthermore, the safety aspect comes into play, as laminated glass ensures occupants are protected from potential hazards during unforeseen events.


The aviation industry has also embraced laminated glass for its numerous benefits. In aircraft, laminated glass is predominantly used in windshields and windows. The durability and shatter-resistant properties of laminated glass add more safety measures, crucial in the event of emergency landings or bird strikes. Moreover, the noise reduction capability ensures a quieter experience for passengers, leading to less fatigue during long flights.


Laminated glass has revolutionized the transportation industry, elevating safety and comfort standards for passengers. Its ability to withstand impacts, resistance to external forces, noise reduction properties, and UV protection make it an ideal choice for various transportation vehicles. As manufacturers strive to enhance the passenger experience and prioritize safety, laminated glass stands as a testament to technological progress. In the foreseeable future, we can expect the use of laminated glass to expand further, benefiting commuters across the globe.
