  • Relatively low investment cost
  • Ideal technical solution
  • lmproved thermal efficiency
  • Enhanced enviromental benefits
  • Good rainwater retention
  • lnstallation is more economical than that of a tully landscaped roof garden
  • ldeal for an inverted roof construction as it provides the advantage of additional roof membrane protection

When should the inverse vs. regular layer order be applied?

A rather complex analysis is needed for answering this question. The benefits of the inverse layer order lie mainly in the protection of the insulation plate and the simplicity of the construction, whereas the regular one is advantageous for the operation of the garden superstructure.

How can lawn-mowing be solved on surfaces accessible from the flats?

This inevitable activity is worth considering already in the design phase, and a maintenance exit should be provided to the roof. A bridging solution might be the use of tiny “droid” mowers that traverses the roof surface frequently enough for the small clippings to remain on the roof without problem.

How long can the lawn be beautiful on the roof?

By providing the grass ongoing and regular care it is easy to ensure that the garden be renewed in the same cycle as the building.
