"Awning companies generally like to have the awning as complete as possible for install to minimize the amount of time on site," Douglas says. "This is where a fabric cover awning has a tremendous advantage over a metal awning, which usually has to be assembled on site." Following the Codes Once assembled, the awnings are installed according to geographical building codes, Douglas says. In some areas, engineered drawings are required for the framing and installation for projections above 36 inches to protect against uploads and snow loads, he says. "Remember, with any type of awning fabric or metal, you have to guard against it coming down and wind blowing it up. If you follow your codes, you shouldn't have a problem," Douglas says. The codes, which differ according to locale, generally require a certain num- ber of fasteners at the top of the awning and outbars at the bottom, Douglas says. "Traditionally, a safe bet is to put Z brackets (another fastener option) on the end of each awning and two feet across along the head," Douglas says, adding that the outbars generally are placed every eight feet but with engineered drawings can be less. The national building code for awnings on commercial buildings also requires the canopy fabric to be flame- retardant. "Some fabricators are sending out fabrics that are not flame-retardant and getting them topically treated, which is like putting on sunscreen. It will wash off over time," Douglas says. Vinyl presents a good choice, since most vinyl is PSV (pressure-sensitive vinyl) receptive or screen printable and provides a level of protection from the rain, as well as being flame-retardant, Douglas says. "They are engineered to withstand the harsh environments around the world," Zola says. "The outdoor life of high-performance digital inks has greatly improved in recent years. Outdoor life can be improved even further by using clear top coats." Adding Graphics Awnings, until the introduction of digital printing about 15 years ago, primarily were white or solid in color without any gradients or graphic images, Yopp says. Digital printing allows for multiple colors and images and works best on softer materials like canvas and vinyl, while the metals go without the additions, he says. "The most prominent trend in installation we're seeing is a movement toward more customization in graph- ics on awnings," Von Wachenfeldt says. "We're seeing everything from logos on a solid colored background fabric to full digitally-printed fabrics. Graphics can be created in vari- ous ways from applying latex paint to a masked-off area to printing on to pres- sure-sensitive or thermal activated film, Wachenfeldt says.
