Application and technical data
Eurovent® GEO GARDEN DUO is used as a horizontal insulation layer in inverted roof systems and green roofs, enabling effective drainage of excess rainwater during heavy rainfall. At the same time, the high studs act as retention reservoirs, supporting the storage of water necessary for plant growth.
The integrated filtration geotextile layer prevents soil particles from entering the stud cavities, ensuring efficient and long-lasting performance of the drainage system.
