A combination of natural and built shade provides the best protection from UV.
Built shade like shade sails, awnings and pergolas can be stand-alone, added onto existing buildings or built next to natural shade. Unlike some forms of natural shade, built shade provides a source of shade all year round. Well-designed built shade uses materials which have a UV Protection Factor (UPF) of 20 or more.3
The Cancer Institute NSW has developed a set of case study examples of well-designed built shade. Read the case studies: How schools, councils, community groups and sporting organisations created shade.
