How Heat Damages Auto Glass

  • Thermal Expansion: Glass expands in heat. Even small chips can spread into long cracks when the temperature rises.
  • Weakened Adhesive: Prolonged heat can soften the adhesive bond holding your windshield in place.
  • UV Degradation: Sun exposure weakens seals and may cause leaks over time.

Step-by-Step: How to Protect Your Windshield in Summer

  1. Park in the Shade: Whenever possible, park under cover or use a sunshade.
  2. Vent Your Car: Leave windows slightly open to reduce interior heat buildup.
  3. Use a Windshield Cover: Reflective covers protect the glass and seals from UV rays.
  4. Avoid Sudden Temperature Changes: Do not spray cold water on a hot windshield. Let it cool naturally.
  5. Repair Chips Promptly: Even minor damage can grow quickly in the heat. Repair your windshield chip today.
