UV rays, high wind, gusts, and rain - basically, normal weather - cause the most damage to awnings. Fading, molding, and tearing fabric. Twisting fixed frames from high wind damage or the weight of snow or pooling rain. In only two or three years, fixed awnings and canopies already show substantial wear, which is why the lifetime of most fixed awnings and canopies is only five or six years before the awning need to be replaced. Retractable awnings are closed when not in use, which cuts weather damage. That makes the maintenance much easier on retractable awnings compared to permanent awnings and canopies - there is no need to hunt down replacement parts, replace fabric every couple of years, or attempt to wrangle awnings down and into storage for winter.
Awning manufacturers have a shorthand jargon that succinctly describes their awnings characteristics, quality, function, even style. Knowledge is the key to having an efficient (and enjoyable) online shopping experience for retractable awnings. These simplified common terms can help you know in advance what youre looking at, so you know how to find what you want. Terms: Parts A lateral arm retractable awning is an awning which can be rolled up and closed; unlike fixed awnings and canopies, a retractable awning has no support posts. A retractable awning has an intrinsically simple design: o Frame - the skeleton of the awning; the frame is comprised of the mounting bar, arms, and roller tube. Mounting bar - the base of the retractable awning which is mounted in place; when the awning is retracted, the awning fabric rolls around the roller tube attached to the mounting bar.
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.
PVC - a hard polymer also used to make plumbing pipes; this tends to be brittle. Kevlar® - the polymer used to make bulletproof vests; Kevlar® straps in the arms instead of cables are extremely strong and durable and cant rust. Cables - braided metal strands which are used in the arms; these are usually steel, which rusts, leading the cables to discolor the fabric and eventually break. Cables cannot be replaced because they are internal to the arm and inaccessible. Terms: Installation Understanding a few terms about the positioning and installation of the awning can help determine the appropriate size and installation location for your awning: o Mount - what way or location the awning is affixed to the home or building, such as a wall mount, eave mount, soffit, or roof mount. Pitch - the angle that the awning comes down from the mount point to the front bar. Some lateral arm retractable awnings have an adjustable pitch. Projection - how far out from the wall the awning can extend. Load - the stress put on the awning, from wind, snow, even the weight of the awning itself (dead load). Good quality retractable awnings can sustain wind speeds up to approximately 35mph Pooling - water buildup on the canopy which can cause the fabric to sag and stretch.
