Green Roofs are increasing in popularity and incorporate vegetation growing media and waterproofing membranes, water retention, drainage and irrigation systems.

In a Green Roof application, VersiCell provides a drainage cavity and an additional protection layer for the water proof membrane(s). It eliminates the need for a gravel drainage course.

Green roofs offer several benefits including:

• Improved Property Value – planted roof areas increase the 'permeable to hard-stand’ ratio on building sites and allow the creation of utilisable commercial and recreational roof gardens and terrace areas.
• Improved Environment – plant species minimise greenhouse gas emissions, pollutants are adsorbed onto growth media particles and plant species provide a habitat for a diverse range of fauna.
• Reduced Energy Costs – radiation is minimised and growth media insulation ensures cooler buildings in the summer and warmer buildings in winter.
• Reduced Maintenance – roofing materials and waterproofing membranes are protected against UV degradation, hail and storm conditions.
• Better Sound Protection – inter level noise transfer is minimised.
• Water Retention – precipitation is retained on site reducing run-off to storm water systems.
