Definitely works to drop the temp when combined with good UV blocking tinting on the other windows. I use mine since the new car has all of these electronics now....heads up display and pop up nav along with trying to preserve the wheel and the dash itself from UV damage.
I agree the sunshade is really more about protecting your interior than lowering air temp.. The main reason regardless of side window tinted or not and why the air temp was the same was the shade is inside the car. The heat has already made it inside the car at that point. Now if you had put the shade on the outside of the window it probably would have made a difference in "air" temp because its reflecting the heat "before" it reaches the inside of the car. However, with no side or rear protection it will only go so far. If you want to block "heat" the protection needs to be outside.
An importance of keeping the dashboard cooler is that the schmutz on the interior of the windshield is due to the plastic particles that melt in high heat and become airborne and stick to the glass
Also keep this in mind: Ambient air temperature wasn't affected, but the hotter surfaces will continue to radiate heat into the cabin after you've gotten into your car and started running your a/c. It'll be easier to cool the car with the surface that is less hot.
170 and 120 temp is just the same hot. anything above 100. i hope some can bring it down to below 100. i really think if the sun shade material is place outside the windshield it will reduce the temp better.
I think a full test would include how long those vehicles take to cool after the vehicle is started. If sun visors reduce surface temperatures (which you have proven) those surfaces aren't radiating heat, which your AC system has to remove. Air has a low mass, so it's easier to cool than the surfaces in your car, which can retain much higher heat energy due to their relatively higher mass than air. Additionally, air is circulated, which cools it faster than objects in your car, which trap heat under the surface. Those objects release heat slowly as the heat is removed on the outermost layer and heat moves slowly outward from the inner layers.
Thanks for posting. I'm trying to figure out if it's worth getting the customized Weathertech sun shade or not--it's roughly 50 bucks. Kraco sun shades are a fraction of the price, at 13 bucks. Based on these findings, the science says that there really isn't all that much of difference between the two in terms of temperature changes.
The windshild blocks most uva and uvb this is why when people get EXPENSIVE transition lenses in their glasses and the sales person doesn't tell them they won't work while driving they come back extremely mad, photocromic lenses are needed for driving
Interesting. However, at least for me, the BEST quality sunscreen is important and you did not even choose a great quality sunscreen so I was disappointed with your work. Maybe you should try again and use a Covercraft sunshade and also The Original Retractable Shade. Then the rest of us would be able to see how they work.
that sucks,i thought it would AT LEAST lower the temperature of the air temperature a littlw bit. That's why I have one. It's nice that it reduces surface temperature though.
People forget the true purpose of sunshades is not to keep ambient temperatures down, but to reduce the surface heat of the dashboard, steering wheel, and other interior- thus prolonging the life of those areas from cracks, fading, and other sun damage.
I usually throw it on when the car is cool inside and it’s going to sit in the sun ☀️ for a while when I get back in the car is cool but I live in southern Cali doesn’t get to 111 degrees in my area 😀
I have ir ceramic tint on rear and side glass put up a sun shade and leavd the sunroof in thd vent position and my car stays zbout 75 inside 0n days its 100°
Now you need to do a test of how fast the Cars cool down from that state, so turn them both back on removing the sun shade from both and seeing if the car that's serfaces are at a lower temp decrease the amount of time it takes for the car to reach Maximum Cold.
Does anyone else notice that after your car has been sitting a while, that the thermometers for the exterior and interior are alot usually hotter than the actual temperature? I think it may have to do with where they are positioned. I am pretty sure some cars temperature sensors are mounted inside the rear view mirror. If that's the case you wont get an accurate measurement unless you drive around and let the surfaces cool
I’m just not partial to that approach. If I left my car outside with the windows open (even slightly), then I would have to be constantly considering the weather conditions and react accordingly. Not a good idea in South Florida, where torrential downpours are a near daily occurrence in the peak summer months. Your mileage may vary in a more suitable climate.
Basically still hot as F...
With more hours, the unshaded air temp would have gotten 20+ degrees hotter. Especially if you crack the windows on the shaded car too.
They don't reduce the heat that much but they will stop fading and cracking of car interiors.
You need to have two exactly identical cars to really pull this test off. There are to many variables in this one.
ya...next time I would try using the newer "white" exterior color offered on sunshades compared with the Silver....

...The use of Sun Shades are to protect The Dash and Steering Wheel from the sun ..... Not The Car Temperature ... OMG!!
I don’t care about reducing heat, what I really care about is filtering UV
I would love to see this tested for convertibles

Thermal mass. If the solid objects don't have as much heat stored up in them, the AC will cool the air temp faster, with less effort. 👍
@@OutsideTheTargetDemographic Yes that is also true
@brotendo wrap your cooler lines so the heat from the engine doesnt affect it much👌
Excellent, short and giving all necessary info.
If you couldn’t tell he is Asian, just look at the terrible parking.

Neat, I always thought it was a placebo effect people used because they thought it made their cars cooler. Nice to see hard numbers disprove that

A sun shade is pointless with a car without at least the standard/factory window tint on the driver and passenger sides.

Kind of a no-brainer. On a hot day the difference between getting into a car with a windshield shade Vs a car without one is pretty dramatic.

I know it's not important but why is one car parked like shit lmao
Surprised by the air temp.

111 is hot! Hope that's dry heat =)
You should put shades on all windows it'll reduce air tempter significantly
how about if u add door window sunshade ?
You should try it with a Weathertech full sunshade kit or cut sunshades for all the windows out of reflectix and do the experiment again
Great job, thanks!
Your windshield blocks virtually all damaging UV radiation, So a windshield, laminated glass, blocks 98 to 99 per cent of all UV.
Awesome video

Direct sun definitely reduces suns damaging UV, which can destroy your dashboard!
Come on man? Do sun shades really work? I live in Arizona every summer is 120. Trust me sun shades work, and window tint, and air conditioning.
111 is far from “toasty.” Lolll

You should always use a sunshade if you don’t have a garage. The UV light will make your dash and leather crack and discolor.

@@ambassador.to.Christ it does not block UVA. The extra heat from the visible light is very damaging too
@@ambassador.to.Christ Yeah and the heat will FRY your software under the dash, it happens.
@@ambassador.to.Christ correct

The sunshade with window tent would greatly reduce the temperatures
Windows tinted , and a sunshade make a drastic difference.
Great experiment. Thanks for taking the time to record video.

I'd like to see an experiment done with these put on the outside of windshield. Stop the heat BEFORE it gets in.
Brilliant idea!
And what I’d like to see is an experiment done on the rear windshield, for those people who only drive in reverse
But how would you keep it intact? A rope or what?
I'd like to see an experiment on how many exterior sunshades are stolen off your car in a year. Lol
@@AdamSmith-fe9jf 🤣😂
really curious to see how having windows opened affects everything

great video , short and to the point
