When horseless carriages first came on the scene in the late 1800s, none had a windshield to protect the occupants. In fact, the first autos were largely open vehicles. Sometimes, these autos had canopies to partially shield occupants from the elements.
It didn’t take long, however, for drivers and passengers to realize that they needed protection from the wind…
while traveling down roads at speeds higher than the normal pace of horses. This, of course, in turn, led to developments such as windshield glass repair. In this article, we will cover some of the highlights that helped develop the windshield as a primary safety feature that you can see in today’s modern-day vehicles.

Early History of Auto Glass
In the early days of the automobile industry, vehicles were outfitted with ordinary plate glass. This glass, while providing basic functionality like visibility, posed significant safety concerns. In the unfortunate event of a collision or rollover, the glass would shatter into large, sharp pieces causing severe injuries. This raised the first questions about safety, prompting the industry to consider alternatives to traditional glass. The increased speed of motor vehicles and the growing number of accidents exacerbated the need for a solution to this dangerous problem.
The Invention of Safety Glass
Safety glass, by definition, is a type of glass specifically designed to break in a way that mitigates the chance of injury. The genesis of this innovative product is attributed to the serendipitous discovery of French scientist Edouard Benedictus. When a flask in his laboratory broke, instead of splintering into lethal shards, it formed a cracked but intact structure. This led him to investigate further, eventually inventing a glass that, when shattered, formed less harmful pieces. In 1909, they were granted the first patent. However, laminated glass was not used commercially until World War I. It was used for the goggles of glass masks. By the 1920s, this ‘safety glass’ was introduced in automobile manufacturing, marking a significant leap in vehicle safety.

Laminated Glass As Auto Glass
Laminated glass eventually found its way into auto glass.
So did the process that bonded the glass to the windshield frame. However, the safety glass was not without problems. The first laminated glass put in cars had a layer that would darken and become brittle over time. In the late 1930s, manufacturers began using Polyvinyl Butyral (PVB) to make auto glass clearer and stronger as well as to help block sound and harmful ultraviolet rays.
By 1937, safety glass became mandated for all cars. Changes occurred slowly throughout the years with innovations like the curved windshield from Studebaker in the 1940s. Manufacturers began using tempered glass for side and rear windows in the 1950s. More styling innovations occurred during this period than safety innovations.

Laminated & Tempered Auto Safety Glass
With the integration of safety glass into automobiles, the march towards better and safer solutions continued. The subsequent decades saw the development of laminated and tempered safety glass. Laminated glass involves bonding a plastic layer between two sheets of glass. When impacted, the plastic layer held the glass together, preventing it from shattering into dangerous fragments.
On the other hand, tempered glass, created by rapidly heating and cooling the glass, shattered into small, harmless granules instead of sharp pieces. These advancements have significantly reduced the potential for injury from broken glass in accidents.
Auto Glass & Your Safety
Not until the advent of the 1960s with consumer advocate Ralph Nader did safety auto glass become a big issue. In response to Nader’s concerns, the U.S. government formed the National Highway Traffic Safety Administration (NHTSA) in 1970 to oversee safety recommendations in American vehicles.
Advancements have moved more quickly since 1980. The NHTSA notified manufacturers that vehicles must use laminated auto glass. Over the last 20 years, the importance of using appropriate safety glass in vehicles to minimize injury during an accident has become a priority.
Since the 1970s, research shows that the use of safety glass significantly reduces the risk of ejection from a vehicle when an accident occurs. The jury is out on whether the auto glass is currently safe. Manufacturers must ensure that the glass that they use is of the highest standards. However, not only is the auto glass that the manufacturers use important but the auto glass that replaces damaged auto glass is equally as important too. This also includes any windshield repairs as well.
So, when looking for windshield replacement near me or windshield crack repair, be sure to be selective about who works on your auto glass. Do not focus on windshield repair cost alone. Your auto glass repair shop needs to be highly qualified and skilled to take on a job that involves your safety.

Auto Safety Glass Today
Today, auto safety glass is subjected to rigorous international standards to safeguard the occupants’ safety. All car windows and windshields are required to be manufactured from safety glass. It undergoes stringent tests assessing its durability, impact resistance, and optical properties. Furthermore, technology has enabled the development of ‘smart glass,’ capable of adjusting its transparency depending on the light conditions, thereby reducing glare and enhancing driver visibility.
Future Trends in Auto Safety Glass
Looking ahead, auto safety glass is set to continue its evolution. Emerging technologies promise enhanced safety features and functionalities. We are already seeing the integration of Heads-Up Displays (HUDs) in windshields, displaying critical information without the driver having to take their eyes off the road. The potential advent of self-healing glass, capable of repairing minor cracks autonomously, and energy-efficient glass, which can regulate a vehicle’s interior temperature, signifies the onset of a new era in auto safety glass.
