Locations futher North will have lower solar altitudes than Southern locations. An angle perpendicular to the Earth's surface is 90° (which only happens near the equator). Solar altitude is the angle of the sun to the Earth's surface. Click the dates above to view the hourly solar altitudes.

The intent of this page is to show you how it works and give you insight into designing a louvered sunshade system that is right for your building, whether it is to be located in Houston, TX or Minneapolis, MN. The benefits can be found in so many articles that we will not go into them here. The primary purpose of a sunshade is to control the amount of direct sunlight through your building's windows. You might also notice them in business offices, where they reduce glare on computer screens, or restaurants, where you can take in the surrounding views.Full Sun in Winter Control the Sun with Sunshades Since solar shades on their own don’t provide as much privacy as other shades, they work best in more public areas like kitchens, living rooms, media rooms, sunrooms and patios as opposed to bathrooms or bedrooms. You might want to consider adding a liner to your solar shades, or for a more dramatic look, layer your shades with curtains. When your lights are on at night, the effect is the opposite and outsiders can see inside. But during the day, you have a little more privacy-you can see outside, but others cannot see into your home. The higher the openness level (the looser the fabric weave), the better you can see through the fabric. A darker fabric is a great choice for larger windows that overlook an amazing outdoor setting. Dark colors, on the other hand, are excellent at reducing glare and providing better view-through. So, if you have small windows or want to brighten a space, a lighter color may work best. Lighter colors better reflect heat and illuminate a room, but the view might be a little hazy (similar to that of sheers). Even if you compare fabrics with the same opacity level, lighter and darker colors work a bit differently. One thing to keep in mind when choosing solar shades is the fabric color. If you have doors in the same room as your windows, you can create a cohesive look by coordinating Designer Screen Shades fabrics with vertical window treatments like Skyline ® Gliding Window Panels. For unusually large windows, Designer Screen Shades are available in widths ranging from 12" to 192" and heights from 12" to 144". They can also fit bay and corner windows. With hundreds of fabrics and opacities, numerous decorative options and a variety of top and bottom treatments, you can customize your solar shades to fit your personal taste. Designer Screen Shades come in openness levels ranging from 0% to 14%, so you have options for filtering light. The higher the openness level, the looser the weave and the less it blocks the light-however, you have better visibility. The lower the openness level and the tighter the fabric weave, the better it blocks the sun-but the less you can see through the shades. Openness refers to how tightly the fabric is woven. They’ll also prevent sunlight from fading or deteriorating your upholstery, carpet, hardwood floors and artwork-and they may even help lower your energy bills! Solar Shades: Openness Explained If your windows overlook gorgeous scenery and a lot of sun is coming into the room, solar shades will block the annoying glare and reduce heat without obstructing your view. Solar window shades (also called sun shades) are roller shades crafted with a specially designed fabric that’s woven just tight enough to protect against UV rays while still optimizing your views.
