Protan Intensive Green Roofs

Intensive green roofs have a thick layer of soil and can be laid out as a roof garden with trees, shrubs and hedges.

Roof gardens with trees and shrubs

The heavy layer of soil provides protection against wind and fire, making it possible to use a loose laid membrane. Intensive green roofs require a strong membrane, so we recommend Protan GG membrane. Protan GG can withstand high water pressure and is not affected by standing water. The membrane adapts with the movement and settlement that occur naturally in structures, and any irregularities in the substrate do not reduce the membrane’s performance. It is also resistant to cold temperatures.

A weather-tight, durable solution

Roofs are required to have a fall to prevent water accumulating on the roof. Protan's solutions with a fall in the insulation under the membrane ensure that the runoff requirement is complied with. Protan GG is designed to withstand heavy loads and high water pressure, as well as having outstanding ageing properties under such conditions.

Root resistance

Protan G and GG have been certified root resistant in accordance with the FLL test (Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau) and do not require extra protection such as root barriers.
