Protan's Turf Roof Membrane is installed on the wooden roof boards with turf directly on top. The resistance of the membrane to roots, combined with its waterproofing properties, means that there is no need to use a drainage layer in the solution.
Turf roofs are a special variant of extensive green roofs and widely used on smaller roof surfaces, especially on holiday cottages in the countryside. In recent decades, modern versions designed for present-day urban needs have been developed. In the countryside, turf roofs help to create environments that integrate with rural communities, while in cities and densely built-up areas they can soften the urban environment.
