Your car’s windscreen is more than just a piece of glass—it’s a critical safety component. It protects you from the elements, supports airbag deployment, and maintains the structural integrity of your vehicle. That’s why discovering a crack on your windscreen can be more than just frustrating—it can be dangerous and costly if left untreated.
So, what actually causes windscreen cracks, and how can you prevent them from happening? Let’s break it down.
Common Causes of Windscreen Cracks
1. Flying Debris and Stones
One of the most frequent causes of windscreen cracks is flying debris, especially on highways or behind large trucks. Small stones can hit your windscreen with enough force to cause a chip or crack, which can expand over time.
2. Sudden Temperature Changes
Thermal stress is a silent culprit. If you blast hot air on an icy windscreen or pour warm water over it in winter, the sudden temperature change can cause the glass to crack. Australia may not experience freezing winters like other countries, but temperature shifts between day and night can still lead to problems.
3. Poor Installation or Manufacturing Defects
A windscreen that hasn’t been installed correctly may be more prone to cracking under minimal stress. Sometimes, manufacturing flaws or weaknesses in the glass also contribute to unexpected cracks.
4. Accidents or Minor Collisions
Even low-impact accidents or closing the door too hard can create enough pressure to cause or worsen a crack—especially if there’s already a small chip present.
5. Structural Stress from the Vehicle
Your car naturally flexes when driving, especially on uneven roads. If the windscreen is under tension due to poor fitting or frame issues, it can develop stress cracks over time.
How to Prevent Windscreen Cracks
1. Keep a Safe Distance on Roads
Avoid tailgating, especially behind construction trucks or vehicles with loose gravel. Staying further back can reduce your chances of getting hit by flying debris.
2. Avoid Sudden Temperature Changes
Allow your car to warm up gradually during colder months. Don’t pour hot water or use extreme heat to defrost your windscreen.
3. Park in the Shade or Use a Sunshade
Long-term exposure to direct sunlight can weaken your windscreen, especially in Australia’s intense summer heat. Parking in shaded areas or using a reflective sunshade can help.
4. Repair Chips Promptly
A small chip can turn into a long crack very quickly, especially with added stress or moisture. Booking a mobile windscreen crack repair Sydney service as soon as damage appears can save you from a full replacement.
