Shade cloth is engineered to comply with the building code.  It comes many different colours from brights to other that blend into the background.  Shade Cloth is permanently out in the weather so expected to be subject to harsh conditions and degradation over time.  It is supported with a 10 year UV warranty.  During this period the fabric will remain serviceable and fit for purpose.  Colour fading is normal over time especially with the reds and blues.
