Slide 3: Why are green roofs installed?
Why are green roofs installed ? Assist with water management: As it is retaining rainwater for plant consumption, run-off is minimized, which reduces the risk of localized flooding. Improve a building s insulating envelope: The green roof is adding an extra layer of insulation which boosts the energ
Slide 4: Are there different sorts of green roofs?
Are there different sorts of green roofs? There are mainly 2 types of roof installations: Extensive green roofs (eco-roofs) have limited or no access. These are lightweight, relatively low cost systems which require minimal maintenance. Intensive green roofs (sometimes known as high-profile roofs) t
Slide 5: What is VYDRO foam
What is VYDRO® foam: VYDRO® foam is a polyurethane-based, lightweight foam with a very high water holding capacity. It is an extremely effective planting medium for roofing and hydroponic projects.
Slide 6: Properties & Benefits
Properties & Benefits Properties of VYDRO® Up to 70% lighter than existing technologies (30 kg/m³) Can take up to 30 times its weight in water Water buffering capacity of 40 60% Water draining: 65% still left after 24 hrs The foam swells 15% after 24 hrs of soaking Benefits Easy to handle / install

Slide 8: What is the life expectancy of VYDRO foam?
What is the life expectancy of VYDRO® foam? Independent testing institutes have assessed the bio-degradation nature of VYDRO® foams against DIN ISO norms. The results indicate that the foam shows no bio-degradation. Life expectancy of VYDRO® foams should be more than 25 years.
Slide 9: How does VYDRO foam work?
How does VYDRO® foam work? Due to the physical, internal structure of VYDRO® foam, water molecules can easily enter its cells but cannot easily exit it. This means that water is stored in the VYDRO® matrix, where it can be readily accessed by plant roots.
