Solutions for green roofs

Green roofs consist of a suitable substrate with selective vegetation, which is installed on top of a waterproofing membrane.

Green roofs provide significant added value and represent practical solutions in the search for sustainability, increased biodiversity and quality of life.

The ecological and economic advantages

Green roofs offer many advantages in terms of ecology and savings:

• Slowing down the heat island effect in cities
• Protection of the waterproofing membrane and extension of its life
• Improving the aesthetic appearance of the building
• Improving the thermal performance of the building
• A natural rooftop environment that absorbs CO2

Extensive or intensive

• Extensive green roofs: the thin substrate allows sedum vegetation and the cultivation of small and medium-sized plants
• Intensive green roofs: the thicker substrate with drainage system is suitable for larger plants, shrubs and small trees. This system is recommended for garden roofs.

In addition to traditional solutions for waterproofing green roofs, Sika offers a wide range of accessories compatible with this type of roof, including draining and filtering layers.
