A drop screen usually enhances an existing structural feature, such as a door or window, or as panels to enclose a porch, lanai, or gazebo. A drop screen requires a sturdy beam to mount to and possibly a door frame or post to fix the side guides to. After finding the location, simply measure the width of the area from side to side on the interior of the frame (for an inside mount) and add for the width of the side guides if mounted outside the window frame. Then measure the height of the screen, going from the inside (or bottom) of the top frame to the bottom of the threshold for the height; for an outside mount, add the size of the headerbox and bottom rail to the height measurement. Finding an ideal retractable awning location has a few other factors to consider.
Awnings have been common for more than 2000 years; retractable awnings have been around for almost 150 years. While the history of using awnings stretches far back in Europe and retractable awnings are commonly used there today, theyre rare in the United States - despite the fact that retractable awnings were invented in the US. This uneven adoption has led to an exposure of design options in Europe - intricate frames, new types of retractable frames, bold colors, and luscious patterns - while America, treating awnings as a practical afterthought, has stayed more conservative. A Quick History Some form of awnings has been around for millennia, starting in Egypt and the Middle East and spreading across the Roman Empire. Most of those were fixed canopies of mats, skins, or fabric bolts hung over poles. In the mid-1800s, shop owners began using movable awnings, which simply bunched up the fabric when it was taken down. In the latter part of the century, they began rolling awnings on a tube, cleanly retracting them and keeping the fabric safe. With minor variation, this is the same basic design used today on lateral arm retractable awnings.
o Canvas - a natural fiber (cotton) woven fabric; canvas awnings are prone to fade, mildew, and rot.o Solution-dyed acrylic - a man-made fiber which is woven into a lightweight, breathable fabric; because it is a chemical polymer, the fabric cannot rot. Solution-dyed means that the pigments are included in the fiber solution, which makes the fabric highly fade resistant. For the frame, the important materials are the body and joints: o Electrostatically powder-coated aluminum - a metal frame which is lightweight, durable, and rust-resistant; powder-coating is a method of applying pigment to aluminum frames which is extremely difficult to flake off or damage, unlike enamel or paint.
For a more thorough cleaning, use a soft-bristled brush and dish soap, working from the bottom up. If there is a persistent stain, mix a quarter cup of soap and a half cup of bleach in one gallon of lukewarm water, and soak the stain for 20 minutes, then rinse.There are some things to avoid when cleaning a retractable awning: Do not use a pressure cleaner, as it will damage the fabric. To prevent mold, mildew, or water stains, make sure that the awning is completely dry before closing it, unless there are high winds. Never use detergent on retractable awning fabric and avoid using the bleach-soap cleaner when possible. Most high quality retractable awning fabrics have several fabric treatments to prevent mildew and stains; harsh cleaners remove that treatment. Avoid heat. Some solution-dyed acrylic fabrics are heat-sensitive and can shrink in steam-cleaning, dryers, and hot water.
