Planted Roof Construction Print E-mail

Background:

  • Historically planted roof structures were common in the extreme climates of Scand6anavia, where the thermal stability of these roofs helped insulate their structures.
  • Recently they have become very fashionable with environmentally conscious design and in countries like Germany it is now compulsory for all public buildings to either have solar or otherwise planted roofs.

Technical information:

  • Planted roofs are either supported on a waterproofed concrete or timber roof decking. Pitches are generally quite shallow.
  • They can be made thinner and hence less heavy by using hardy shallow rooted local species of bulbs and succulents.

Benefits:

  • Planted roofs are visually unobtrusive. Helping to integrate buildings with their landscapes.
  • They help reduce the carbon footprint of construction by maintaining the carbon sink of the site.
  • Planted roof improve the insulation of the roof structure
  • Planted roofs reduce the maintenance of roofs as they help maintain a stable temperature of the building structure, reducing its continual movement and protecting the waterproof layer from harmful u-v rays.
  • Absorb pollutants and reduce the urban heat island effect of developments helps reduce the air conditioning loads on buildings.
  • Slows and reduces the loading on storm water systems.
