1. Is there a standard size?
That's a perfectly rational question, as windshields come in a variety of dimensions. A car sun shade will not fit the windshield of an 18-wheeler. The dimensions for standard size are 24 "x 58" and fits most compact to mid-size vehicles, while the dimensions for the large are 27 "x 67" and are perfect for SUVs and RVs. Its best to start by measuring your car's front windshield to determine the exact size you need.
2. Should I still buy them if I already have tinted windows?
Yes, yes and yes. Now we can not stress this point enough. The fact is that even if your windows are tinted all the way around, if you tint your car's entire front windshield you're screwed – your car is pretty much useless. At best most front windshield tints only cover a tiny sliver at the top, leaving about 95% of your windshield and dashboard exposed to direct UV rays and merciless heat. Until manufacturers find a way to install transition lenses as front windshields, drivers will have to rely on the car sun shield is.
No matter how much your other car windows are tinted, the majority of heat and damage will come through at the front, while your backseat passengers get hit with a blast of heat the moment they open the car door. Eventually you will have to replace your car's entire dashboard when it becomes cracked along with any electronics and gadgets in your vehicle that got fried. Online retailers make it affordable and easy to own car sun shields, so you can pay almost nothing for a car accessory that will protect your largest investment apart from your home.
3. Do they really work?
Yes, feel free to try them sometime.
4. I have a car sun shade with one side reflective and the other side matte white. Which side of my car sun shade is supposed to face out?
Most shiny surfaces reflect both light and heat, while matte surfaces absorb light and heat. Initially the answer might not seem so obvious but it's the reflective or shiny side of your sun shield. Note to the rookie, please make a point of removing your sun shade before driving off into the sunset.
5. Which design is best?
