Can Cold Weather Make Your Windshield Crack?
Understanding the Effects of Temperature on Windshield Material
Windshields are made of laminated glass, which is a type of safety glass that consists of multiple layers of glass and plastic. The plastic interlayer, usually made of polyvinyl butyral (PVB), holds the glass together in the event of a break. When subjected to extreme temperatures, the glass and plastic can expand and contract, potentially leading to cracks.
During the winter months, windshields are exposed to cold temperatures, which can cause the glass to contract. This contraction can lead to stress on the glass, making it more susceptible to cracking. Additionally, the expansion and contraction of the glass can cause the PVB interlayer to become brittle, increasing the likelihood of a crack.
Studies have shown that windshields are more likely to crack when the temperature drops below 40°F (4°C). At this temperature, the glass and plastic can contract by as much as 0.1 inches (2.5 mm), putting additional stress on the windshield.
Factors that Contribute to Windshield Cracking in Cold Weather
- Temperature fluctuations: Sudden changes in temperature can cause the glass to expand and contract rapidly, leading to stress and potential cracking.
- Humidity: High humidity can cause the glass to become more prone to cracking, as the water molecules can seep into the glass and cause it to expand.
- Pre-existing damage: If the windshield already has minor scratches or chips, the cold weather can exacerbate these imperfections, leading to a full crack.
- Windshield age: Older windshields are more likely to crack in cold weather, as the PVB interlayer can become brittle over time.
Real-World Examples of Windshield Cracking in Cold Weather
Many drivers have experienced windshield cracking in cold weather. For example, a study conducted by the American Automobile Association (AAA) found that windshield cracking is a common problem during the winter months. The study revealed that:
| Month | Percentage of Windshield Cracking |

Factors Contributing to Windshield Cracking in Cold Weather
Temperature and Material Expansion
Cold weather can cause a windshield to crack due to the thermal expansion of the glass material. Most windshields are made from laminated glass, which is composed of multiple layers of glass and a polymer interlayer. When exposed to cold temperatures, the glass expands and contracts, creating stress within the material. If the stress becomes too great, it can lead to cracking.
The thermal expansion coefficient of glass is typically around 0.000012 per degree Celsius, meaning that for every degree of temperature change, the glass expands or contracts by 0.000012 of its original length. While this may seem like a small amount, it can add up quickly over the course of a cold winter day.
Additionally, the adhesive properties of the polymer interlayer can also play a role in windshield cracking. As the glass expands and contracts, the adhesive can become weakened, leading to a loss of structural integrity and potentially causing a crack to form.
It’s worth noting that not all windshields are created equal, and some may be more prone to cracking in cold weather than others. Factors such as the type of glass used, the thickness of the glass, and the quality of the adhesive can all impact a windshield’s resistance to cracking.
De-icing Methods and Their Effects
De-icing methods can also play a role in windshield cracking. While de-icers may be effective at removing ice and snow from the windshield, they can also cause damage to the glass if not used properly.
Rock salt, for example, can be particularly damaging to windshields. When rock salt is applied to the windshield, it can seep into the gaps between the glass and the frame, causing corrosion and weakening the structural integrity of the glass.
Other de-icing methods, such as using a scraper or a de-icer spray, can also cause damage to the windshield. If not used carefully, these methods can scratch or chip the glass, creating a weak point that can eventually lead to cracking.
It’s essential to use de-icing methods responsibly and to follow the manufacturer’s instructions when using any de-icing products. Additionally, it’s a good idea to apply a windshield treatment or sealant to help protect the glass from damage caused by de-icers.
