Maturity stage
TRL 9 / CRI 3-4 - Commercial Scale Up / Multiple commercial Applications
Over the past decade, the technologies used in roof vegetation have not evolved. Namely logistics complications, such as the weight of traditional substrates, or the installation and maintenance of the green roofs. VG Holz aims to provide an all-in-one solution: green roof, installation of waterproofing, and IoT sensors to monitor the impact and performance of the green roof. VG Holz substrate is a new complex that, due to its density and physical characteristics, can be installed on almost all roofs. One of the main specificities of the product is its light substrate, renewable and fully compostable, 100% made in France. The solution also offers greening more urban areas and participating in the development of urban food autonomy through rooftop urban agriculture.
