How Does a Carport Stop Frost from Forming on Your Car’s Windows?

January 3, 2019

Anyone who lives in an area that experiences cold winters has dealt with a frosted windshield. Scraping a layer of ice off the glass in the morning is a trying chore that can leave you wishing it was summertime already. The best way to stop this is to park the car inside of a garage or under the cover of a carport. It makes sense that the all-encompassing coverage of the garage would keep the windows free of frost, but carports in Phoenix, AZ can do the same thing without the high construction and maintenance costs of a garage.

How is this possible, though, since a carport is completely open on multiple sides? Let’s take a closer look at how an open carport stops frost from forming on the windows of your car.

How frost is formed

Warm objects, including cars, radiate heat. The car generates heat while running and rapidly loses heat after it is turned off. As the car cools below the frost point of the air, the water in the air starts to condense on the glass, which results in the formation of frost. This process continues until all the water in the air condenses into that annoying window frost.

Carports retain heat

The carport slows this entire process down significantly. The top of the carport absorbs the warmth of the sun during the day. The carport is warmer than the outside air and sky, even when the temperatures cool down at night. The roof radiates heat down into the carport and into the ground. The heat stays within the space and keeps the area much warmer than the chilly outside air even when the temperatures dip far below freezing. The carport also acts as a physical barrier that protects the car from moisture condensation on the glass. The water will condense everywhere else, instead of inside the carport. A car parked inside of a carport in Phoenix, AZ will be safe from frost on even the coldest nights.

Why it matters

Most people write off a cold car and icy windows as a side effect of winter, but the cold temperatures can have negative effects on your car. Regular exposure to cold temperatures can drain the voltage of the battery, making it harder for the car to start. The cold air can also cause the tires to rapidly lose pressure. Most tires lose approximately 1 psi every time the temperature drops by 10 degrees. Under-inflated tires are more likely to perform poorly or even fail in chilly conditions. The oil, antifreeze, power steering, brake and transmission fluids will begin to thicken once the temperature drops below 35 degrees. The car won’t be able to function properly if the fluids don’t flow at the right pace.

Don’t waste your time scraping ice off the windshield. Save time and keep your car working great even in the winter months by installing a carport in Phoenix, AZ. Call the experts at Diamondback Carports today to learn more or schedule a consultation.
