Sunbrella Grade B
Sunbrella is a woven synthetic canvas fabric from Glen Raven Mills, Inc. that is made of 100% solution dyed acrylic fiber by Du Pont, which has the highest resistance to deterioration from ultra-violet sun rays. We’ve been using Sunbrella almost exclusively for over thirty years now, and can vouch for it’s phenomenal longevity in continuously exposed sunlight. Reasonably priced, yet amortized over its lifetime, and offset by the protection it provides, this fabric effectively pays for itself.
For use outdoors, it’s definitely worth the initial investment. The furniture grade Sunbrella fabrics weight 8.00 oz per square yard. These fabrics are much softer making them ideal for cushions, drapes, upholstery, and shower curtains. These fabrics have a three year warranty against mildew and fade.
