Moveable awnings are one low-tech way to maximize the passive solar benefit of windows in the winter, while keep the summer’s harsh rays from sending your air conditioner into overdrive. And with today’s advance fabric technology, these awnings have a 10- to 15-year lifespan. The fabric can then be replaced easily. Sunbrella, a specialty fabric produced by Glen Raven Custom Fabrics in North Carolina, is used for high UV exposure applications, including patio umbrellas, and outdoor cushions, sail covers and boat cushions as well as other applications. Not only is the fabric available in a wide array of solids and stripes, your manufacturer will keep a record of the awning dimensions so replacement is a breeze. Sunbrella’s parent Glen Raven also recently was awarded membership in the South Carolina Environmental Excellence Program, with their comprehensive recycling program.
