Protan Green Roofs

Green roofs with turf and grass are an ancient Scandinavian construction technique that goes back hundreds of years.

Old Scandinavian construction technique

Green roofs retain water, as well as offering aesthetic and environmental benefits. In principle they can be used on any roof slope, but are mainly recommended for slopes of up to 30 degrees. The watertight membrane is covered with vegetation.

Good for the environment

Using plants in the composition of the system means that the building is cooler in the summer and insulated better in the winter. Energy consumption can be reduced, and green roofs help to deaden increasing noise in cities, while trapping dust and particles from the air. Plants on the roof also help reduce the greenhouse effect.

Roof gardens mean that we have more recreational areas and make better use of space in cities, and they are new habitats for birds, insects and animals. The water retention can relieve the strain on drainage system in densely built-up areas during heavy rainfall.

Several types

There are several types of green roofs:

Did you know that in days gone by birch bark was used for waterproofing under turf roofs?

Protan Extensive Green Roofs

Extensive green roofs are characterised by the roof being covered with a thin layer of soil or growing medium mats, typically planted with succulent and moss species.

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.

Protan Turf Roofs

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 water proofing properties, means that there is no need to use a drainage layer in the solution.
