Using Geofoam for Green Roofs
Growing awareness and concern for our environment have increased the interest and applications of green roofs. Geofoam is the ideal insulation for green roof construction. This environmentally sound roofing construction also offers long term cost savings. The overall environmental benefits include stormwater management and temperature regulation. For a consumer, a green roof offers insulation, which reduces energy costs and extends the life of the roof.

Why Use Geofoam for Green Roof Design?
Geofoam is a lightweight substance that reduces downward pressure while retaining its compressive strength. It can be pre-cut for specific jobs, allowing for limitless customization of the landscape design with a quick and less labor-intensive installation. Geofoam is CFC, HFC, HCFC and formaldehyde-free in addition to being recyclable, which is ideal in an environmentally friendly design.
Insulation is a key element for a successful green roof. Geofoam, made of expanded polystyrene (EPS), provides an insulation layer that maintains its R-value over time. Available in various densities, R-values and sizes, it is the ideal solution for installation under the vegetation of a green roof design.

Proud to be LEED-ing the Way with LEED® Points
In accordance with US Green Building Council (USGBC) standards, Alleguard’s ICA-LITE® EPS Panels and Geofoam may provide LEED® points for construction projects. Members of USGBC developed the Leadership in Energy and Environmental Design (LEED®) Green Building Rating System to establish practices for designing, constructing, and certifying sustainable buildings. Learn more about the LEED program can be found at www.usgbc.org as well as our LEED Guide.
Alleguard Geofoam meets or exceeds the requirements of ASTM D6817, Standard Specification for Rigid Cellular Polystyrene Geofoam.
Benefits of a Green Roof Made with Geofoam:
- Stormwater Management
- Reduces Heating and Cooling Costs
- Increases Roof Longevity
- Improves Air Quality
- Fire Retardation
- Opportunity to contribute to LEED® points
- Reduces urban heat-island effect
- Noise Reduction
- Aesthetic Value
- Creates Valuable Amenity Space
Why EPS?
EPS has high R-value retention, is fully recyclable, and is easily customizable. EPS is made without ozone-harming compounds or any kind of dye. It is available in a variety of compressive strengths and has superior bonding capabilities. Best of all, EPS will save you time and money. So the real question is: Why not EPS?
