Green Roofs continue to grow in popularity, especially in large urban areas. These areas can suffer from the “Heat Island Effect” which is caused by black roofs, black asphalt parking lots, concrete and lack of green space. Green roofs, also known as “living roofs” or “vegetated roofs” use plants to lower roof temperatures and create a biodiversity ecosystem encouraging additional habitats of plants and animals.
Plymouth Foam has been involved in numerous green roof projects and have noticed that Engineered DuraFill EPS (GeoFoam) has turned out to be the best solution. Here are the reasons we discovered:
- DuraFill EPS is a closed cell, yet breathable to expel moisture
- DuraFill EPS holds its R-value and does not leach chemicals
- DuraFill EPS can be manufactured formed to accommodate water flow
- DuraFill EPS has high compression resistance for loading
- DuraFill EPS has larger payback and lower costs
Plymouth Foam’s DuraFill Green Roof Products can help reduce cost by combining several products into one combination product reducing labor installation costs. Where most systems have insulation above the waterproofing membrane exposed to moisture, DuraFill can be engineered to move water more efficiently to the drains. DuraFill EPS can be designed to have predictable compression for walkways, loads and foot traffic.
Using your roof to create garden or outdoor living space can greatly reduce your heating and cooling costs. It can also help to reduce the Heat Island Effect.
A properly designed Geofoam Green Roof can increase the life span of the roofing system by improving water flow, reducing ultraviolet exposure to the roof membrane and reducing insulation below the waterproofing membrane which lowers thermal roof stress.
