How Cold Weather Affects Your Windshield and What To Do About It
Winter in Calgary, AB, brings icy roads, frigid temperatures, and an increased risk of windshield damage. At Minit-Tune and Brake Auto Centres, we understand the unique challenges that cold weather presents for drivers, especially when it comes to keeping your windshield in top condition. In this article, we’ll explore how cold weather affects your windshield, the most common issues drivers face, and practical steps you can take to prevent or address these problems.
The Science Behind Cold Weather and Windshield Stress
When temperatures drop, your windshield endures a constant cycle of contraction and expansion. The glass contracts in the cold but may suddenly expand when exposed to heat from a defroster. This repeated stress can lead to cracks or exacerbate existing chips. Calgary's harsh winters, with temperatures frequently dipping below freezing, can turn small chips into major problems if left untreated.
Additionally, road salt and ice scrapers can scratch the glass, weakening its structural integrity over time. Combine this with the risk of flying debris from sanded roads, and your windshield faces a season full of challenges.
Common Windshield Issues in Winter
- Cracks and Chips:
Sudden temperature changes, such as blasting your defroster on a frosty morning, can cause tiny cracks to form or worsen. - Frost Buildup:
Ice and frost can cling stubbornly to your windshield, requiring repeated scraping that may scratch the glass. - Wiper Damage:
Cold weather can make wiper blades brittle, reducing their ability to clear snow and ice effectively. - Visibility Issues:
Fogging from inside the cabin, combined with exterior frost, often creates visibility problems during winter drives.
Proactive Measures to Protect Your Windshield
1. Repair Chips Immediately:
At
Minit-Tune and Brake Auto Centres, we recommend addressing chips or small cracks as soon as they appear. A quick repair prevents further spreading and saves you from costly windshield replacement.
2. Use a Windshield Cover:
Protect your windshield from frost and debris by using a cover overnight. This simple step reduces the need for scraping and prolongs the life of your windshield.
3. Warm Your Car Gradually:
Instead of blasting hot air directly onto a frozen windshield, start with the defroster at a lower temperature. Gradual warming minimizes thermal stress and helps prevent cracks.
4. Replace Wiper Blades Regularly:
Invest in winter-grade wiper blades designed for Calgary's cold conditions. These blades remain flexible and provide better snow-clearing performance.
5. Use Washer Fluid Rated for Winter:
Make sure your windshield washer fluid is formulated to resist freezing. Look for products rated for temperatures as low as -30°C or below.
6. Avoid Harsh Scraping:
Use a quality ice scraper with a rubber edge to gently remove frost. Avoid aggressive scraping that could scratch or chip the glass.
