WARNING: On a sunny 90F day, Air trapped inside your parked vehicle can
heat up within minutes. Dashboard and steering wheel can be as hot as 180F,
seats can be 160F! Protect your vehicle and more importantly, protect your
Cooler cabin reduces fading, cracking and discoloration on interior parts!
Cooler ride means less AC duty cycle, means less fuel!
Cooler ride bring you comfort, peace and calm; reduce body stress level and maybe
helpful to avoid traffic ticket or accident!
Use windshield sunshade is able to keep vehicles interior an average of 40F cooler!

Darker interior vehicle can build more heat up
So, a darker color automobile gets a lot hotter during sunny days?
Not really. The darker painted sheet metal gets a lot hotter than
light colored sheet metal. However, all the heat from the outside
of a modern vehicle can only transmit into the cabin very slowly
thanks to the insulation material we have today. Good insulation
material makes heat dissipate into the inner cabin very slowly.
Unlike our fathers' days, a white car or a black car doesn't make
much of difference. That’s also the same reason why we can
discount most of the heat from a hotly running engine. However,
if your vehicle isn’t well insulated, that can be a different
story. A touch from inside your vehicle cabin roof during a hot
summer day can tell you about how well your car is insulated.
No matter how hot the day gets and how dark your
vehicle’s skin color, the temperature from inside your cabin roof
should be just few degrees higher than its ambient temperature. If you have a hot roof during a sunny day, that's a sign
of weak insulation, and it still happens on few lower end models. If your vehicle has such a problem, you can either DIY or
ask your auto body shop to put in better insulation for you. That will help not only when you park, it will also offload AC
duty when you drive as well.
In contrast, interior color plays a much more important role than exterior color. As we said earlier, dark material tends to
transform more light into heat. Due to good insulation, heat from outside is kept outside. However, for the same reason,
heat generated from inside the cabin remains trapped inside. Heat also builds up thanks to poor ventilation when parked.
Without ventilation, heat can’t dissipate into the environment freely. It's like a greenhouse, but worse. That's why darker
interior cars can get much hotter during summer days than others. Choose lighter colored interior that won't generate as
much heat and tint your windows to block sunlight from getting into your vehicle. These steps will certainly help you to
keep your car cool all year long.
What can we do to cool it?
1, Ventilate your car.
If there is no security concerns, roll your windows completely down when you park under sunlight; unfortunately, we don't
live in a world like this. Leave your windows open just a little if you are concerned about security. Sunroofs are better
vents since hot air tends to rise higher. Just tilting open your sunroof can let a lot of hot air get out. I would use a moon
roof curtain to stop sunlight getting in from a transparent moon roof. Either way, remember to close them when it rains.
2. Stop sunlight from getting into your vehicle cabin.
Park under a shade, if you can. However, shaded lots can be hard to get when it's hot out. In addition, another price you
often have to pay if you do park under a tree is bird droppings. If you can't find a shaded spot or are afraid of bird
droppings, use sunshade or tint your window to stop sunlight from getting into your vehicle cabin. Car covers also helps if
you have the time to put them on.
3. Change interior color.
If you are about to choose a new vehicle, remember these facts: dark interior generates more heat, and try to pick a
vehicle with smaller window area. If you still have to live with your current vehicle for a long time like rest of us, or there
are other concerns when choosing a vehicle, there are other ways to improve. For example, use light colored seat covers
or place a light colored towel above your dashboard and steering wheel when you park. Of course, always use sunshade.
A light absorbing dashboard top is the worst heat converter
The worst heat source for a parked car is commonly from near the windshield area. The windshield is typically large and
has an inviting angle to sunlight from above. For night time driving safety, very little or no tint at is allowed for
windshields. Moststates prohibit any tinting on windshield. For day driving safety, the material used around the windshield
area is intended to absorb sunlight and not allow much reflection. Reflection from these area would likely reflect on the
inside surface of the windshield and interfere with the driver’s vision. For example, both the top of the dashboard and
steering wheel tend to absorb sunlight that shine on them and transform them into heat. They generate lots of heat when
they are directly exposed to sunlight. Sometimes they become burning hot. Use a good windshield sunshade when park
certainly helps a lot to cool down your cabin. The percentage or actual temperature drop as result of sunshade depends
on other conditions such as how much sunlight makes it through your other windows and the color of your cabin interior.
However, roughly 40F lower on a hot day is an approximate figure. If you only have time to do one thing before leaving
your vehicle, put a windshield sunshade on.

|Color plays an important role here too. The darker an object gets, the less it reflects less light.
However, it transfers more into heat. Darker color interior vehicles build up more heat than lighter
interior vehicles do.
|Why vehicle cabins get so hot?
Let’s look at the facts about how the cabin
of our parked automobiles can get so much
hotter than the environment during a hot
sunny day. There are two major heat
sources: sunlight and engine exhaust heat.
We will tell you why sunlight plays a much
more important role than engine exhaust
heat in just a little while.
When sunlight reaches non-clear objects,
part of it reflects out as visible light (That’s
why we can see objects as much brighter in
day than night) and part of it becomes heat.
This happens everywhere around your
vehicle where sun light touches. It happens
to the metal, dashboard, chairs, etc.
