Standard patio roofing is constructed using thin sheets of metal.Aluminium or Colorbond panels sit directly on beams with very little buffering.This allows sound to travel across that surface easily.This sound could be of rain, wind, or even branches that brush the roof. This issue of noise pollution becomes noticeable during storm season, when heavy downpours make conversations under the patio roof difficult. Insulated patio roofing structures behave completely differently, as they have a rigid foam sandwiched between metal layers. https://stylemasterpatios.com.au/insulated-patio-roof/
