In A Nutshell A piece of material suspended between fixed points to offer shelter from the sun.
A little more detail Shade Sails are made from quality, shade cloth -which is a material (ideally a mix of high density Polyethylene with a filler thread or tape), that has a stainless-steel wire sewn into the perimeter. Shade Sail’s are suspended between posts or wall/roof hooks and provide shade coverage. Designs are based on ‘sails’ from ships, and come in almost any shape but are usually created as triangles or variations of squares/rectangles.
The ancient Egyptians, Greeks and Romans were the first recorded people to use large pieces of fabric to create shade. The Colosseum in Rome was shaded with hundreds of large canvas ‘sails’ which were put into place by Roman sailors.
The modern Shade Sails were developed to a commercial level in Australia in the 1980s, when people started experimenting with different shade cloth materials and installation methods.
Although the concept of a shade sail is simple, the differences in design, components and manufacturing processes will largely affect your end result.
