Do External Sun Blinds Function?

Outdoor sun shades are a growing trend in insulation and protection from the sun. They provide shade and sun protection to outdoor spaces and windows, blocking or filtering sunlight, reducing heat, and creating more energy. Solar shades are similar to roller shades but made from PVC or HDPE mesh, while roller shades are typically vinyl or fabric. They are mounted on the home’s exterior to filter out sunlight and UV rays while still providing a view to the outdoors.

Exterior solar shades work by using sunlight to energy the system and create shade, which can block out a large amount of sunlight, reducing energy usage and helping to cool your home. Different types of outdoor shades include retractable solar shades, which work like screens and are easier to control, and awnings that extend to cover certain outdoor areas, like your patio. The main difference between interior solar shades and exterior solar shades is where you install them: inside or outside.

Surface solar shades are made with weather-resistant fabric and hardware, so they are more effective at blocking the sun’s heat and keeping your home cool in summer. They offer a sleek, contemporary finish to all kinds of properties and can add value as soon as they are installed. A single solar shade blocks 99 of the UV rays and lets 1 through, making them an excellent option for homes with large windows.

In addition to heat blocking, exterior sun shades are excellent for reducing glare, particularly beneficial for homes with large windows. The level of privacy provided by outdoor solar shades depends on the openness rating of the fabric. Overall, exterior shading can be more effective at shading and cooling a home, as well as preventing the harmful effects of the sun.

Can sunshade crack a windshield?

In El Paso, summer temperatures are causing a surge in sun damage to windshields. Sun shields are commonly used to keep as much sun out of cars as possible. However, a shiny, aluminum foil-like sun shield may not be the best option for preventing windshield damage. A car parts store expert advises against using a reflector shade cover, especially if you have a windshield glass chip. Shiny shade covers can intensify the heat on your windshield, leading to dings turning into full-on cracks, especially in triple-digit heat.

A shiny sun shield may not be the best way to keep the heat out of your car, especially in triple-digit heat. Instead, opt for a more durable and durable sun shield that can withstand the heat and damage caused by the sun.

Can you see in from the outside with solar shades?

Solar shades are transparent during the day due to the penetration of external light through the window. However, at night, the primary light source is located within the home, resulting in the shades becoming opaque when viewed from inside the house. This phenomenon reverses the situation in which solar shades are see-through during the daytime.

Do windshield sunshades keep car cooler?

A car windscreen sunshade can reduce your car’s interior temperature by up to 30 degrees, providing an affordable solution to keep your car cooler during the hot Australian sun. The sunshade works by reflecting the sun’s rays of light, which are absorbed by the car’s interior, such as the seating and steering wheel, and heat up. Without a sunshade, the heat can’t escape the car, causing mild burns and shocks when reaching for the seatbelt. To prevent this, a sunshade can be placed on the dashboard, allowing more light to be reflected, preventing the car interior from heating up.

This can be particularly beneficial during the summer months when the car is scolding you for not being cool. Novus has provided a compressive guide on why you should pick up a sunshade this spring, highlighting the benefits of using a sunshade.

Do solar shades keep cold out?

Solar shades reduce heat by blocking sunlight and making windows more energy-efficient. They can save money on energy costs during hot summer months. However, the holes in the woven fabric do not allow the shade to insulate against cold. For a window treatment that blocks drafts and cold outside temperatures, consider cellular shades. Solar shades in Sheerweave 14 Pale Gray are a popular choice for this purpose.

How much heat do solar shades keep out?

Solar screens can significantly reduce heat by blocking up to 90% of the sun’s heat-producing rays, reducing indoor temperatures by up to 15 degrees. However, the exact amount of heat reduction depends on factors like local climate, direct sunlight, and screen type. Solar screens are also environmentally friendly, reducing the need for air conditioning and lowering carbon footprint. They also help lower energy bills by reducing AC usage. However, actual results may vary based on factors like local climate, sunlight intensity, and screen type.

Are sun shades better inside or outside?

Exterior solar screens block the sun before entering a home, preventing more heat gain than interior sunscreens. They can reduce heat gain by up to 80, while interior shades can reduce it by up to 40. Sunscreen fabrics are designed to block sun while maintaining a pleasant view, depending on the openness factor of the fabric mesh. Exterior rolling sunscreens provide more privacy during the day, as they are on the outside and prevent people from seeing inside the home.

However, at night, a more closed mesh of 3 or below is harder to see through and provides more sun protection and privacy. Interior rolling sunscreens may allow some visibility from outside, especially if they are very open mesh fabrics. Exterior sunscreens also reduce glare more effectively than interior sunscreens, filtering out more bright light that can cause eye strain and discomfort. However, interior sunscreens may still allow some glare to pass through, depending on the openness factor of the fabric mesh, angle, and intensity of sunlight.

Do outdoor shades reduce heat?

Exterior shutters and shades, made from various materials like fabric, wood, steel, aluminum, or vinyl, are effective in reducing solar heat gain. Insulated cellular shades, made of pleated materials, fold up accordion-like at the top or bottom of the window and contain one or more air layers in a honeycomb cross-section. These shades have the highest R-values of all window coverings, as the air pockets act as insulators, increasing the R-value and reducing heat conduction. Insulated cellular shades offer significant energy savings, comfort, privacy, and increased home resale value.

How do you block sunlight from windows cheaply?

It is recommended that aluminum foil be considered as a cost-effective and efficient solution for window covering, as it effectively blocks out light and is readily available.

Exterior shades, crafted from weather-resistant materials, serve as a protective barrier against the damaging effects of ultraviolet (UV) radiation. This not only creates a more comfortable environment for both indoor and outdoor spaces, but it also minimizes glare.


📹 Sun Shades, do they really work?

This video tests the effectiveness of sun shades in reducing heat inside a car. Two identical cars are used, one with a sun shade and one without. The video measures both air temperature and surface temperature of various areas inside the cars to determine the sun shade’s impact. The results show that while the sun shade doesn’t significantly reduce air temperature, it does make a noticeable difference in keeping surfaces cool.

  • These shades, in conjunction with quality window tint. have been proven to work. I live in South Texas and its mid summer right now. I bought a 2010 Chevy Malibu and going to lunch at 12pm is no joke with this heat. My car was about 150 degrees inside, with it being about 99 degrees outside. I added the solar shade and now my temp was at about 110 degrees inside, with it being 100 degrees outside. HUGE difference, and the life of my dashboard will be extended drastically. Best 10 dollar investment so far for my car

  • 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.

  • I have one cause none of my windows are tinted I just keep it in the back seat when it’s hot out or I know cars going to be sitting for awhyll I throw mine up on the front window. Mines a little big but it works the centre mirror and the sun visors help hold it up. It’s not a 100% perfect fit but it dose help keep the car cool and helps keep the dash from getting destroyed by the sun. So no cracked or warped dashes I like mine it was cheap but gets the job done and only takes 2 seconds to put up

  • 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

  • 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.

  • 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.

  • 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.

  • i got one for free so its whatever to me but i use it on a regular for the fact that it keeps the direct sunlight off any electronics in the front of the car plus with the windows cracked it helps quite a bit compared to nothing at all. either way when it gets really hot there is no way around the fact that the cab is gonna be lit especially when you have a black paint job like i do or these cars. even with all the windows blocked off its gonna get toasty.

  • i drive a suv and it came with the back windows already dark, just the front ones dont have a tint or nothing, i use a windshield sun shade for my dash and just hang them sun screens on driver and passanger the difference is really noticeable. and even before i tint them it was still noticeable the back was considerable cooler than the front, you wouldnt burn your ass, arms and back. with the whole windows some what blocking the sun reduced the tempeture to few ° above the tempeture outside the vehicle. its worth doing it.
