In Manchester, UK, a lightweight green roof has been installed on a private residence. The addition of a green roof in urban areas doesn't only offer advantages for the residents, like extending the life span of the roof, adding value to the house, and reducing ambient noise. The neighbours also benefit from for example the lower ambient temperature, increase of local biodiversity, and air purification.
Special lightweight structure
Some flat roofs aren't able to support a heavier traditional green roof. Especially for these situations, Sempergreen has developed a lightweight green roof. With a maximum saturated weight of 45 kg/m2, this system makes it possible to create a green roof on places where this otherwise would be impossible. Due to the use of mineral wool fibers as the growing medium, the green roof is light yet still able to store water. A mix of 6 to 8 different kinds of Sedum ensures that the roof blooms with a splendor of colours.
