There is a lot of controversy on the use of car sun shades. But do car sun shades really work? We all dread getting back into the car on hot days.

The dashboard, the steering wheel and the seats sometimes become too hot to touch. This when we start considering acquiring good and cool car sun shades.

Do Car Sun Shades Work?

Studies conducted by University of California have shown that if a car was left in the sun for 1 hour. The car’s dashboard temperatures can reach up to 157 degrees F, the steering wheel up to 127 degrees F while the seats can reach up to 123 degrees F on average.

Having some shade on the windscreen reduces this heating effect.

Car sun shades are said to reduce significantly this heating effect and keep the car cool.

If your question is, do car sun shades work? Yes they do. The majority of shades have a reflective surface which bounces the sunlight rays and thus prevents them from hitting the objects in the car. This prevents the rise of car interior temperatures.

We have personally done an extensive research and here is a highlight of how sun shades work.

What are Car Sun Shades Made Of?

A car sun shade is a protective shield placed on the inside of your car’s window or sunshield to reflect the sun’s rays. They are also known as heat shields, UV shields, or sun shields.

Car sun shades are made from dual layers of mesh material designed to protect from UV light without affecting visibility. The mesh may have a layer of aluminum foil, mylar or nylon material.

Some car sun shades have suction cups in their corners to attach them to the windshield.

How do Car Sun Shades Work?

When you leave you car in the sun, visible light enters through the cars’ windshield. This light is absorbed by objects inside the car. The light is then converted into infrared light.

Infrared light gets blocked by the glass on the windows. The trapped infrared light builds up with time heating up the interior of the car.

Car sun shades have a reflective surface that reflects lights.

When visible light hits the shiny car sun shades, most of it bounces back as visible light meaning it does not get trapped by the glass.

If you are thinking, do I need a sunshade for my car, you ought to know that having a sunshade in your vehicle reduces the amount of visible light that enters your car. This reduces the heat build-up in your car if left in the sun.

Additionally direct sun, can heat up the car’s dashboard. Prolonged exposure to direct sun causes the dashboard to fade and eventually leading to cracks.

Other items left in the car such as laptops or other electronics may also be damaged by direct sun.

Car sun shades reduces direct sun light passing through the windshield protecting the dashboard or electrical devices left in the car.

Lastly, when the infrared light is trapped in the car, it heats up the air in the car which cannot leave. This produces the greenhouse effect. This is dangerous especially to kids and animals if left in the car.

Having a car sun shade reduces direct sun light, reducing the greenhouse effect in cars left in the sun.
