Green lungs on your rooftop

Extensive green roofs generally need minimal maintenance and have many uses. Because they are light, they do not need as strong a load-bearing construction as intensive green roofs.

Extensive Green Roofs

Extensive green roofs are covered with a thin layer of soil or growth-medium mats.

Typical plants used on these roofs are species of succulents and moss. Sedum is widely used in Norway, and roofs covered with this plant are known as sedum roofs.

Extensive green roofs generally need minimal maintenance and have many uses. Because they are light, they do not need as strong a load-bearing construction as intensive green roofs.

The roof membrane has to be calculated for wind force and installed mechanically. It may be necessary to use concrete slabs or something similar at the edges and corners, where wind force is strongest. Sedum mats can act as a ballast on the roof but can only be planted in warm seasons.

Stringent requirements for fire safety

Permission to install an exposed roof membrane, until the sedum mats are placed, is only granted if the membrane meets technical demands around fire safety. Protan roof membranes are self-extinguishing and classified for fire in accordance with BROOF (t1-t4). Larger roofs must have fire barriers. The growth medium must have fire barriers and concrete slabs, pebbles or similar material at the edges and penetrations to stop the spread of fire.

Protan SE Titanium+

Protan SE Titanium+ roof membranes are a sound solution for sedum roofs. They are documented to be root resistant in accordance with the strict FLL (Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau) test and thus do not need extra root protection.
