Why Do Car Windshields Crack? Common Causes & Prevention Tips

Car windshields are very important for your car. If they crack, they can result in a disastrous situation. Drivers often consider them to be just glass windows that offer a clear view of the road, and in the real world, the windshield is a well-designed section of engineering that provides safety and structural integrity, besides protecting the occupants.

After a crack has been spotted, the majority of drivers overlook it, citing a minor cosmetic issue that cannot influence the visibility of a car, its structural integrity, and the performance of airbags in a collision, in some instances. The small crack widens over the years due to vibrations, weather, and pressure, thereby presenting safety hazards and rendering repairs costly.

In this article, we are going to discuss the most common causes of windshield cracks, the type of cracks that you must be aware of, the reasons why a broken windshield should never be ignored and some of the real-life preventive measures you can take to save your vehicle. How and when a change of the front glass of a car is necessary, the possibility of the best windshield services near me, and the security of the support of the windshield specialist at all times are also the issues that we will discuss.

The Role of Car Windshields in Vehicle Safety

Car windshields are not just simple opaque covers but a safety feature that is valued and therefore directly contributes to the level at which a car can operate during accidents or extreme conditions on the road.

•  Collision Structural Support: The car windshields are able to sustain up to 30 per cent of the strength of your car. It also assists in ensuring that the roof is open during rollovers to avoid fatal injuries that cause the death of passengers. A broken windshield reduces this by a great deal.
• Airbag Functionality: In most of the current automobiles, airbags are fitted to control the force exerted on the windshield before the passengers are cushioned. The airbag may cause a faulty or bonded windshield to break, thus being less effective and giving the airbag some weaknesses that can lead to negligence in the security of the passenger.
• Shield against highway risks: The windshield must be the front line defence against flying rocks and even birds on the highways, dust and so forth. Any crack reduces its resistance to the influence, which leads to further susceptibility to fracture under the impact of minor steps.

Common Causes of Car Windshield Cracks

Car Windshield cracks occur not by chance and are a result of an external factor, environmental influences, or mechanical forces. These are the most common causes, and we will subdivide them.

1. Impact from Road Debris

Windshield damage are often a result of loose gravel, small rocks or debris. Even a pebble can crack a chip or a star. The crack spreads with time due to the vibration of the road and alterations in the weather. As the number of trucks that are transporting construction material increases, the risk also increases.

2. Fluctuation of Temperature (Thermal Stress)

Laminated glass layers are what is commonly used as car windshields. These swell and contract with temperature. It may crack the glass when you pour cold water on a hot windshield, or when you operate a heater/AC too intensively. These cracks are usually noticed by the drivers when they are changing the season, particularly in areas where there are hot summers or freezing winters.

3. Inadequate Glass Repairs or Installing cheap glass

A poorly installed windshield is always under strain. The adhesive bond may be weakened by even the normal vibrations in driving and cracks on the edges. On the same note, a glass of low-quality or counterfeit is weaker than OEM glass and therefore, it is more susceptible to the effects of stress and impact. This is the reason why it is important to select certified technicians and original parts.

4. Accidents and Collisions

Damage can be caused by windshields even through minor collisions. The effect is not always instant and breaks the glass, but creates the points of stress that are invisible. With time, these weak spots grow into cracks that are visible. Banging the door of the car when the windows are closed could also cause an internal pressure, making the small cracks grow longer.

5. Changes in Pressure and Vibrations

Windshields keep changing pressure while driving. Going through tunnels, speeding through mountainous areas, or high-speed headwinds may put pressure on the glass. Add to this the additional daily vibrations due to potholes, rough roads, or even loud music with heavy bass, and stress cracks may develop without being hit.

6. Weather and Environmental Conditions

Also of significant importance are harsh weather conditions. During windy weather, deep chips are formed by hailstorms, and the falling branches make serious cracks. The degradation of the laminated layer of glass caused by exposure to UV rays over a long period makes it brittle and prone to immediate fracture under pressure.

7. Manufacturing Defects

Less frequently, there are other windshields that are manufactured with minute flaws or defects. These defects could take several months before they become cracks due to the normal driving loads. This explains why trusted manufacturers and adequate quality inspection are important in the replacement of car windshields.

Types of Car Windshield Cracks

Identifying the type of crack helps determine whether repair is possible or if car front glass replacement is required.

• Chip: Small damage caused by stone impact. It prevents spreading if you repair it immediately.
  
• Bull’s Eye: Circular cracks resembling a dartboard. Usually repairable if small.
  
• Star Break: Cracks radiating from one point, spreading rapidly if ignored.
  
• Combination Break: A mix of bull’s eye and star cracks, harder to repair.
  
• Edge Crack: Originates from the windshield edge, usually requiring replacement.
  
• Stress Crack: Appears without impact due to pressure or thermal stress.
  
• Long Crack: Extends beyond 15 cm. This often requires full replacement.
  

Cracked Windshield: Never Ignore It

1. Fractured Structural Safety:

Windshields have been made to support some of the weight of the vehicle in the event of a rollover. A broken one will reduce the support of the roof of the car. Therefore, this will be rendering it susceptible to collapsing. This renders neglect of cracks a direct source of death to the passengers.

2. Loss of Airbag Effectiveness:

Airbags are deployed in places where they fit against a windshield. A broken windshield could break and lead to the malfunctioning of airbags. This lessens the efficiency of cushioning and subjects the passengers to a higher risk of grievous assaults in even minor collisions.

3. Smoking Mirror Vision of the Driver:

Light is distorted by cracks, and glare occurs. On sunny afternoons or when oncoming headlights come at night, they distort vision and distract drivers. They cause more accidents. Small cracks, even around the view of the driver, are perilous.

4. Risk of Shattering Increases:

The presence of a crack compromises the integrity of the windshield, and it is likely to splinter under some extra tension. A full break can be caused by hitting a pothole, banging doors, or drastic weather changes that can be dangerous to the passengers immediately.

5. Increased Long-term Repair Cost:

A chip can be repaired cheaply and quickly. When this is neglected, then it propagates cracks over the windshield that need total replacement. The price of front glass replacement of a car is much higher and time-consuming than a quick repair.

6. Potential Legal Issues:

Several places consider driving with a cracked windshield to be pretty unsafe. The police can impose fines, failing your car when examined or even asserting that it is off the road. A quick fix will make the road safety laws valid, and penalties can be avoided.

7. Lower Vehicle Resale Value:

Customers view the occurrence of broken windshields as an indicator of bad maintenance. This decreases your car’s bargaining power and value. Before selling, changing the windshield enhances beauty, confidence in the buyer and the market price of your car.

Prevention Tips to Protect Car Windshields

It is always cheaper and safer to prevent than make replacements. The following are tips that can be offered to prevent cracks:

1. Keep a Sufficient Space on the Roads:

Maintain a safe distance with other vehicles. Especially, when they are bigger vehicles like trucks, buses, and construction vehicles, you must keep distance. So, you don’t have the risk of construction materials or debris harming your vehicle.

2. Precautions in Temperature Change:

Stop your windshield from quickly changing temperatures. In the summer, wear sunglasses. This helps stop cracks from forming because of heat stress.

3. Park Smartly:

As much as possible, park in garages or other shaded places in order to minimise the effects of UV. The trees provide shade, but branches that may fall. 

4. Select Professional Services:

Shun home-made solutions that offer short-term solutions. Resin and adhesives used by a certified windshield are of professional quality, which means that they would restore original strength. Repairing as a profession also covers the warranty, and you can be sure that your glass will be safe and will last longer.

Why Consult a Windshield Expert?

1. Accurate Damage Assessment

An expert who deals with windshields does not simply examine the size of a crack, he/she analyses depth, position and structural safety. Their precise judgment can make you save on unnecessary replacement, and at the same time, no unseen dangers can be hiding behind the road.

2. Application of Sophisticated Adhesives and Curing

Professionals employ the industry-grade adhesives and specific methods of curing that reinstate the windshield strength to the factory level. Their procedures are designed to make the glass stick and not crack under the pressure, as well as last, unlike fast and easy DIY solutions, which offer short-term prospects in changing weather and driving conditions.

3. Stringent Safety Requirements in Installation

When installing windshields, certified technicians work according to the rules of manufacturers and the strict safety measures. Since proper alignment is necessary to avoid accidents later, and even if the airbags are functioning correctly, they ensure that the installation is in accordance with safety standards, and will not make the installation leave the safety regulation view.

4. Warranty and Peace of Mind

Professional windshield services usually have warranties on any repair/replacement. This will ensure that in case the cracks come back as a result of labour faults, you are insured. Being aware that you have the security of a service guarantee on your glass also puts you at ease, as well as gives you permanent peace of mind.
