There’s nothing quite like an aimless day trip on a hot summer day. Windows down, volume up, nowhere specific to be. The only catch is that once you cut the engine and step outside, the interior temperature of your ride starts climbing—as much as 20 degrees in just 10 minutes.
Being slammed with a wall of heat when you open the door is bad enough, but no one wants to play hot potato with a seatbelt buckle. While a windshield shade won’t change the weather, it will make entering the cabin much more bearable (and ensure you can actually grip the steering wheel without branding your palms).
Below, we explain how these accessories work their magic, the different types you can buy, and what to look for when shopping. Simple, low-cost, and perennially overlooked, this might just be your smartest purchase of the summer.
What Does a Windshield Shade Actually Do?
When you park in the sun—even on a cool day—light shines through the windows, heating up trapped air and interior surfaces to create a greenhouse effect. A windshield shade simply helps block and/or reflect that light before it can enter the cabin.
Ambient air temperature still rises (sorry, that’s just science), but solid surfaces will be cooler to the touch. They’ll also be better protected from the sun’s harmful UV rays, which can cause interior plastics and fabrics to crack, warp, and fade.
Since 80% of the temperature rise inside a car happens within the first half-hour, these accessories tend to make the most noticeable difference on short trips—like popping into the grocery store or attending a doctor’s appointment. A full workday in the sun is a tougher ask, but at least the seatbelts won't feel like cattle brands.
Benefits of Using a Windshield Shade
Studies show that, even in consistently hot climates, windshield shades can reduce dashboard temperatures by 30 to 40 degrees compared to having no sunshade.
With less heat trapped in the dashboard, your car’s A/C won’t have to work as hard to cool down the cabin. This not only reduces wear and tear on the system’s blower motor and compressor, but also lets you enjoy ice-cold air in half the time. Come winter, the shade has a similar effect on your car’s heating system—preventing frost build-up on the inside of the windshield and helping reduce defroster load.
Another benefit of a sunshade is privacy. By blocking the windshield, you limit visibility into the cabin, which is useful if you tend to leave personal items on the seats or in the cupholder.
Perhaps the most underrated selling point, though, is that it takes virtually no time to set up these accessories. You simply unfold or unroll the shade, depending on the style, and situate it flat against the windshield. Use the sun visors to help secure it into place and you’re good to go.
Why use a sunshade?
- Reduced surface temperatures inside the cabin
- Protection from damaging UV rays
- Improved air conditioning efficiency
- Frost prevention in winter
- Added privacy in the cabin
What to Look for When Shopping
While the purpose and design of windshield shades are pretty straightforward, there are still a few things to consider when choosing the right one for you.
- Fit: While universal options are cheaper, they don’t provide the same coverage as a custom-fit solution specifically designed to match the size and shape of your windshield.
- Performance: It may be tempting to grab a sleek blackout shade for privacy, or a decorative one for personality, but the classic silver options are the most effective for managing heat. Their reflective surfaces bounce UV rays and infrared heat back out through the windshield, helping to reduce cabin temperatures. The dark shades actually absorb heat, making them useful in winter, so some manufacturers offer dual-sided options.
- Construction: Some windshield shades include a foam core, which not only provides stability to the shade but also helps trap its own residual heat and keep it from reaching the car’s interior. This insulating layer can also keep the car warmer in winter.
- Installation: Some models unfold like an accordion, while others unroll, and still others “pop up” via a twist and fold motion. This last style is probably the most storage-friendly, as they’re compact enough to tuck into a seatback pocket, but they’re often not as durable as the rolling and folding styles.
- Brand: Certain companies are renowned both for producing quality options and innovating in the space. When it comes to windshield shades, that would be WeatherTech and Covercraft. Though, you’ll find excellent selections from Husky Liners, CoverKing and Plasticolor as well.
- Complementary Products: While a windshield shade will help with direct sunlight, you can’t always guarantee a parking spot facing the sun. Passenger and rear window shades can help provide all-around coverage, while seat covers and dashboard protectors can help combat wear-and-tear that occurs when driving. For the most comprehensive protection, professionally installed window tint is worth considering. It permanently reduces UV exposure and heat gain on all windows, not just the windshield.
