2. Space sunshade - Wikipedia

   en.wikipedia.org/wiki/Space_sunshade

   A sunshade could potentially be one climate engineering method for mitigating global warming through solar radiation management, because internationally negotiated reductions in carbon emissions may be insufficient to stem climate change. [5] [6] Sunshades could also be used to produce space solar power, acting as solar power satellites ...

3. Sun protective clothing - Wikipedia

   en.wikipedia.org/wiki/Sun_protective_clothing

   UPF (ultraviolet protection factor) represents the ratio of sunburn-causing UV without and with the protection of the fabric, similar to SPF (sun protection factor) ratings for sunscreen. While standard summer fabrics have UPF ~6, sun protective clothing typically has UPF ~30, which means that only 1 out of ~30 units of UV will pass through (~3%).

4. James Webb Space Telescope sunshield - Wikipedia

   Coupons of Sunshield test fabric being tested to see how they perform, 2012. Northrop Grumman designed the sunshield for NASA. [17] The sunshield is designed to be folded twelve times so it can fit within the Ariane 5 rocket's 4.57 m (15.0 ft) diameter by 16.19 m (53.1 ft) shroud. When it deployed at the L2 point, it unfolded to 21.197 m × 14. ...

5. Windshield sun shade - Wikipedia

   en.wikipedia.org/wiki/Windshield_sun_shade

   Typically, sun shields are made of a layer of mylar or aluminum foil which covers the inside of the car's windows, to reflect the sun's rays away, and preventing the interior from being exposed to those rays. There are sunshades specifically designed to fit the inside of the front windshield of the car, and others designed for the car's side ...

6. Window screen - Wikipedia

   en.wikipedia.org/wiki/Window_screen

   An 18×14 mesh has become standard; 16×16 was formerly common and other common sizes are 18×18 and 20×20. For comparison, a typical screen in a clothes dryer has a nylon 23x23 mesh screen. Fiberglass solar screens provide over 75% of UV protection, by using thicker strands and a closer mesh than regular 18x14 fiberglass window screening ...

7. Shade sail - Wikipedia

   en.wikipedia.org/wiki/Shade_sail

   Shade fabrics are measured by their shade factor, which is the measure of how much a shade fabric absorbs or reflects invisible light (ultraviolet radiation). This is listed as a percentage out of 100, with a 100% shade factor indicating complete light blockage.
