STYROFOAM™ Brand Insulation, LEED and Green Roof Assemblies (218KB PDF)
A protected membrane roof assembly incorporating STYROFOAM™ Brand Extruded Polystyrene Insulation can help building owners meet the goal of sustainable design and construction — including contributing to the achievement of USGBC or CAGBC Leadership in Energy and Environmental Design (LEED) credits.

Sustainability Objective |
PMR Benefit |
|
Reduce the total energy consumption of the building (life-cycle costing) |
PMR performs year after year — and the more a roof can be kept in use, the more it contributes to the overall sustainability of the building by delaying the impact of eventual tear-off. |
|
Reduce global warming impact from excessively using energy sources (reduce) |
A PMR using a rigid, extruded polystyrene insulation, with one of the highest R-values per inch, will realize reductions in utility bills, year after year. By reducing HVAC loads, this will lower pollution emissions from burning fossil fuels. |
|
Reduce the downstream waste during construction, maintenance and demolition phases (reuse, recycle) |
Because the insulation, fabric and ballast are loose-laid in a PMR, many times these components can be reused after maintenance or major construction. |
|
Offer recycled content and/or reusable products (recycle) |
Dow incorporates recycled materials into its finished goods. For example, Dow has been internally recycling trimmings from the production of STYROFOAMâ„¢ Brand Extruded Polystyrene for more than four decades. Scrap, such as cuttings from board edge treatments, is recycled back into finished products, reducing waste and storage and landfill costs. |
