Guide

Have you ever wondered, “Can heat crack a windshield?” As temperatures rise, this becomes a crucial question for car owners. For a car owner, it is essential to know the causes of windshield cracks, especially those that occur because of temperature effects on glass.
 
Yes, heat does make the glass weak and susceptible to damage. This is especially relevant during the summer months when protecting your vehicle from the heat to avoid windshield cracks becomes a part of essential auto glass maintenance.
 
In this article, we’ll explore how heat affects your windshield and offer some valuable tips for summer car care to ensure your vehicle remains in top condition. We’ll also discuss the vital steps for windshield repair in case damage or cracks occur due to the heat.
 

How Heat Affects Windshields

Heating of the windshields is not just a summer nuisance but a risk to the integrity of your auto glass. Here’s how temperature affects your car’s windshield:
 

  • Expansion and Contraction: Glass expands when it is heated and contracts when it is cooled. A constant cyclic process of expansion and contraction tends to stress the windshield, making it prone to damage.
  • Edge Stress: The edge of a windshield is mounted firmly in the frame, which reduces relative movement. This also means that when the material expands due to thermal expansion, the chances of the edges cracking are higher.
  • Material Fatigue: Over time, the windscreen material can get worn due to repeated exposure to stress from temperature changes. This can weaken the material, increasing the likelihood of cracks.

 

Spot the Signs: When Heat Takes a Toll on Your Windshield

Understanding the signs of heat-related damage in windshields is essential for timely maintenance and repairs. Here are some common symptoms:
 

  • Stress Cracks: Stress cracks generally start from the edge of the windscreen and travel inwards. These result from thermal stress and do not arise from direct impact but rather from extreme temperatures.
  • Distortion: Heat can cause slight warping of the windshield glass, which might be noticeable when viewing through it. This distortion can interfere with your vision while driving.
  • Delamination: Extreme heat may cause the laminated glass layers to separate, forming bubbles or a foggy view of the glass.

Being alert to these signs can help prevent windshield cracks from worsening. Start the season right by ensuring your windshield is prepared to handle the heat. Contact Auto Glass America today for a comprehensive check-up, and drive worry-free this summer!
 

Preventive Measures: Pro Tips to Guard Your Glass

Here are some practical tips you can easily implement to protect your windshield from the heat:
 

  • Use Sunshades: A sunshade is a protective sheet that can be attached to the inside of a windshield or side window to prevent damage caused by sunlight. Putting sunshades on your windshield and windows can decrease the temperature building up inside the vehicle and help minimize the stress on the glass.
  • Park in the Shade: When possible, park the car under a shade. This simple step can prevent direct heat or sunlight from hitting the windshield and keeping your vehicle cool.
  • Tint Your Windows: Consider adding a windshield film that protects your car from most of the harmful UV rays. Remember to choose a film that complies with your state’s laws for window tint visibility and reflectivity to ensure safe driving and legal compliance.
  • Ventilate Your Car: Leave your windows slightly open when your vehicle is parked in hot weather. This will allow hot air to escape and reduce heat build-up, which can lead to glass damage.
  • Regular Inspections: Ensure you inspect the windshield regularly for any indication of stress cracks or damage, especially after a heatwave. Early identification can help you avoid expensive and complicated repair procedures.

By incorporating these summer car care tips into your routine, you can extend the longevity of your auto glass.
 

Immediate Actions for Heat-Damaged Windshields

Discovering a crack in your windshield can be alarming, especially if it’s due to heat. Here’s what to do to ensure safety and minimize further damage:
 

  • Assess the Damage: Check how big the crack is and where it is located. If it is a small crack and not in your immediate line of sight, it is safe to drive to the auto glass repair shop. However, if the crack is large or if there are multiple cracks, it is best to choose on-location mobile windshield services to get it attended immediately.
  • Apply a Temporary Seal: To prevent the crack from spreading, you can apply clear packing tape as an interim solution. Tape over the crack on the windshield’s exterior so moisture and dirt cannot get inside.
  • Avoid Temperature Extremes: Until you get the windshield repaired, do not park in direct sunlight, and do not use the air conditioning on high. Severe temperature changes could make the crack worse.
  • Contact a Professional: Arrange an appointment with an auto glass expert like Auto Glass America to inspect and make proper repairs to the windshield. Quick professional intervention can prevent a full replacement.
