Sun protection for cars: How to avoid a heat build -up

Especially in summer, cars can heat up strongly: if a vehicle parks longer in the sun, there is a so -called heat build -up – for this reason, no living beings (neither human nor animal) should be left in a standing car. But the onward journey is also a pain as long as the air conditioning has not yet cooled down the interior temperatures. It seems all the more useful to attach sun protection. In order to find out which model best helps against the heat, this has tested different accessories in Landsberg on the Lech on seven vehicles. In the following we will tell you the result of the engineers.

A note in advance: When buying, make sure that the corresponding sun protection is tailored to your car. Here, too, there are different sizes that are not equally suitable for every vehicle.

You have the option of having the side windows and rear window tones tones to reduce the heating development. According to the ADAC, the desired effect is only slightly, more precisely, the interior temperatures only drop by two degrees, but the surface temperature on the back seat should be noticeably removed: “Without tinting 57 degrees, with tint only 48 degrees”. It is important for you to know that certain regulations go hand in hand with a slope tone. You can read exactly which one.

According to the study from the ADAC technology center The best sun protection for the car. This is a large cover tariff that is stretched around the vehicle so that all windows are covered. As part of the test phase, it could be found in such a way that the interior had “only” heated to 43 degrees after installation – ten degrees less than in a car that has no sun protection at all.

On the other hand, the attachment of the : A sun protection for the windshield, which is attached from the inside. After all, the temperature inside could be reduced by four degrees – so nothing speaks against the installation, even if the difference to a car without sun protection is hardly noticeable. In addition, the ADAC points out that the effect only occurs if the aperture sits on the windscreen without gaps. “Often this is not the case and the effect is even lower.”

In addition to the half -garage, the -According to the German Automobile Club e. V. – A satisfactory solution: In contrast to the sun visor, the sun protection is attached to the outside on the windshield. This should reflect the sun’s rays so that the vehicle interior (especially the fittings and seats) cannot heat up so much. According to the study, the air temperature in the test vehicle was eight degrees “colder” than that in a car without sun protection.

And two more tips at the end: Due to the direct sunlight, the fittings and the steering wheel heat up so strongly (up to 70 degrees are possible) that they can burn themselves when they contact the skin. For this reason, the ADAC recommends attaching a sun protection – or they cover both to lower the surface temperature. In addition, it is advisable not to leave any sensitive devices (such as your smartphone) in the car when it is parked in the sun.
