Unattached or Freestanding Awnings
Typically fastened
Regular awnings are typically fastened to a window frame, door frame, or even to the roof. These outdoor shades then hang over the windor or door structure and provide shade. However, a hybrid type product is being sold which stands somewhere between a canopy and an awning: a freestanding awning. They are also known as unattached awnings, meaning that they are not affixed to the house.
Unattached awnings are composed of fabric stretched onto a frame which is then attached to two poles, one at either end. The fabric of unattached awnings cover a space as would a regular awning. The great advantage is that these awnings can be moved around to where they are needed most. They also cover much great area than a simple umbrella. Regular attached awnings must be retracted or expanded for shading, but the freestanding awning only need to be tilted to the right angle for shading. The frames of the awnings can be made from a variety of materials, such as metal or vinyl. Installation is not easy though, as the awnings are extremely heavy and need a very sturdy base to hold them.
Differences from canopies
In concept, canopies and freestanding awnings are very similar. The major difference is that the canopy rests on four legs whereas the unattached awning only on two. The canopy is designed as a roof-like structure so that tables and other things may be placed under it. A freestanding awning is very much like an extended shade "hangs over" an area, giving the feeling of an area that offers a view toward some particular direction toward which the awning is pointing. In practice, the two are similar. In feel and atmosphere, the canopy is more functional but the awning is more recreational.
Structural Shades
"Freestanding" is a bit of a confusing term because sometimes it includes the so-called structural shades such as the gazebo, pergola, trellis and arbor. Arbor designs in particular is a popular request for homeowners who are into the aesthetics of the front yard and garden.
