All You Need To Know About Car Windshields: A Vital Safety Feature

Team AckoDec 21, 2023

Car windshields are one of the most essential and often overlooked components of an automobile. While we tend to focus on the engine's power, the interior comforts, and the aesthetics of our vehicles; the windshields don't get enough attention. Car windshields play a critical role in ensuring safety and comfort while driving.

In this article, we will cover everything you need to know about car windshields, from their construction and materials to maintenance and replacement.



How is a windshield constructed?

Car windshields are not just simple sheets of glass. They are designed with multiple layers to ensure strength and safety. The primary components of a car windshield include:

1. Outer Glass Layer: 

The outer layer is typically made of tempered glass. This glass is specially treated to be more resistant to shattering upon impact. It is designed to withstand small stones, debris, and minor impacts without breaking.

2. Middle Plastic Layer: 

Beneath the outer layer lies a middle layer made of a transparent plastic material called Polyvinyl Butyral (PVB). This layer is crucial for holding the glass together in case of a collision, preventing it from shattering into dangerous shards.

3. Inner Glass Layer: 

The inner layer is also made of tempered glass and serves as a second layer of protection in case the outer glass shatters.

What are the functions of car windshields?

1. Visibility: 

The windshield provides a clear and unobstructed view of the road, ensuring the driver can see and react to any potential hazards.

2. Holds up the structure: 

The windshield contributes to the structural integrity of the vehicle, providing support to the roof and preventing it from collapsing during a rollover.

3. Weather Protection: 

Car windshields shield occupants from rain, snow, wind, and debris, ensuring a comfortable and safe driving experience.

4. Airbag Deployment:

Modern vehicles rely on the windshield as a backstop for airbag deployment. The windshield helps direct the airbag towards the vehicle's occupants in the event of a collision.

Tips for maintenance and care of your car’s Windshield

Proper maintenance is essential to ensure the longevity and effectiveness of your car's windshield:

1. Cleaning: 

Regularly clean both the interior and exterior of the windshield to remove dirt, bugs, and other debris that can impair visibility.

2. Repair Chips and Cracks: 

Small chips and cracks should be repaired promptly to prevent them from spreading. Many minor windshield issues can be fixed without the need for a full replacement.

3. Replace Worn Wiper Blades: 

Damaged or worn wiper blades can scratch the windshield's surface, reducing visibility. Replace them as needed.

4. Avoid Extreme Temperature Changes

Sudden temperature changes, such as pouring hot water on a cold windshield, can lead to cracks. Gradually warm up or cool down the windshield to prevent damage.

Points to consider while replacing your car windshields

Sometimes, windshield damage is too severe to repair and there's no choice but to get a replacement. Here are some key points to consider when replacing a windshield:

1. Professional Installation: 

Always have a trained and certified technician replace your windshield to ensure proper installation and safety.

2. OEM vs. Aftermarket Glass: 

OEM (Original Equipment Manufacturer) glass is designed specifically for your car's make and model, ensuring the best fit and performance. Aftermarket glass may be cheaper but may not meet the same quality standards.

3. Calibration: 

Many modern vehicles rely on cameras and sensors mounted on the windshield for safety features like lane departure warnings and adaptive cruise control. After windshield replacement, recalibration of these systems is crucial.
