Chapter 1: Introduction To Shadesails

Over recent years, shadesails have become increasingly popular. In many public spaces such as schools and parks, the provision of shade is now a statutory requirement. This is understandable when it can take just 11 minutes of exposure to mild UV radiation for the skin to exhibit the first signs of sunburn. Shadesails today are sophisticated structures that are designed and engineered to look great and be safe in a variety of conditions. They are made from advanced polymers (usually polyethylene with UV inhibitors) and are designed to withstand the suns UV rays for up to a decade. Of course, this has not always been the case and shade sails in some form have been around for thousands of years. The shadesails today are essentially an evolution of the ancient Bedouin tents. These tents were constructed using wooden columns with a canvas canopy stretched over them and held secure by guy ropes. Like this one many had sides and were used as living quarters. Shadesails today typically don’t have sides, they only have the roof structure and are installed more to provide safe UV zones for short-stay outdoor activities.

Shadesails have become popular as they;

• are a cost effective way to span large areas
• look aesthetically pleasing
• are a proven system for blocking UV Radiation
• are infinitely flexible in size, shape and design
• are relatively easy (once you know how) to install

Commonly referred to as ‘tension membrane structures’ the types of shadesails we discuss in this book are quite sophisticated. They use the latest technology in shading materials and rely on engineer certified columns and fittings to create striking structures that not only look spectacular but also provide high levels of UV protection. In fact, it is recommended that the shades today provide a minimum level of at least 94% UV protection.

Why install a Shadesail

The simple fact is, most Summer outdoor activities these days require us to protect ourselves from UVradiation (UVR). Whether it’s sunscreen, shade or protective clothing, the provision of some UV protective during the hotter months of the year is now mandatory. The provision of high quality shade in outdoor areas where people congregate is arguably the safest form of protection there is.
