Description

Built-up sedum green roofing system.


Features and benefits:

  • Water is cleaned when passing through a green roof system and has the potential to remove pollutants and particles.
  • Stormwater run-off.
  • Habitat for rare wildlife.
  • Energy efficiency.
  • Improved thermal properties.
  • Roof life span can be increased up to 3 years.
  • Air quality improves by reducing polluting air particles.
  • Sound insulation, 20–100 mm dry growing medium could help achieve sound pressure level attenuation of 10–40 dB, frequency depending.


The system comprises:

  • Vegetation layer.
  • Growing media.
  • Filter layer.
  • Drainage layer.
