what is the sun shade in a car called

The item you’re referring to is most commonly called a sun visor when it's the built-in flap above the windshield. However, the removable shade you place on the windshield is typically called a windshield sun shade or car sunshade. These accessories are crucial for protecting your car's interior from UV damage and reducing interior heat.

The primary purpose of any sun shade is heat rejection and UV protection. Prolonged exposure to direct sunlight can cause your dashboard to crack, fade upholstery, and damage electronic components. A quality sunshade can lower the cabin temperature by up to 40-50°F on a hot day, making the car more comfortable to enter and reducing the load on your AC system.

There are two main types to consider:

• Built-in Sun Visors: These are the flip-down visors above the windshield and sometimes the side windows. They often have a sliding extender for better side coverage and a mirror with its own cover.
• Aftermarket Sunshades: These are removable and come in various forms, from foldable cardboard models to high-tech collapsible shades.

Feature	Foldable Sunshade	Roll-Up Sunshade	Electrochromic (Smart Glass)
Ease of Use	Moderate; can be awkward to fold	Very easy to store and deploy	Permanent; no manual effort
Coverage	Excellent; custom-fit available	Good; may have slight gaps	Perfect; entire windshield
Heat Rejection	Up to 99% UV, significant IR	Up to 98% UV, good IR	Variable; reduces glare and heat
Cost	$15 - $50	$10 - $30	$500+ (OEM option)
Durability	Foil layers can crease and tear	Fabric can be durable	Long-lasting with no moving parts

For the best results, look for a shade that offers 99% UV protection and is a custom-fit for your specific car model, as it will provide the most complete coverage. While a basic universal shade is better than nothing, a well-fitted one is a worthwhile investment for preserving your car's value and comfort.

We just call it a sunshade. You know, the fold-up thing you slap on the windshield when you park. It’s a lifesaver in the summer. The car isn't an oven when you get back in, and it keeps the steering wheel from burning your hands. I keep one in each of our cars. The kids’ car seats don’t get dangerously hot, which is my number one reason for using it. Get a decent one; the flimsy ones fall apart in a season.

Technically, the official name is a "sunshade," but you'll hear people just say "sun visor," which can be confusing. The flip-down thing above your head is the visor; the thing you put in the window is the shade. I’m picky about my car's interior, so I invested in a custom-fit shade that matches my make and model. The difference in coverage and heat reduction compared to a cheap universal one is night and day. It’s all about protecting your investment.

It’s a windshield sun shade. I’m a big fan of the roll-up kind because they’re so much easier to handle than the folding ones that never seem to go back the right way. The main point is to block the sun, obviously. It keeps the temperature down and stops the sun from baking your dashboard over time. That sun damage adds up and really hurts your car’s resale value. It’s a simple, cheap trick that pays for itself.

The removable one is a sunshade. I look at it from a practical angle: it’s a thermal management tool. By reflecting sunlight, it significantly reduces the thermal load on your vehicle's interior. This means your air conditioner doesn't have to work as hard to cool the cabin, which can save a small amount of fuel over time. More importantly, it prevents long-term material degradation from UV exposure. For a few dollars, it’s one of the most cost-effective protective accessories you can buy.
