Sika Roofing and DuPont Join Forces in Sustainability

Roofing systems don’t have to be disposable. By maximizing system longevity and recycling at the end of its useful life, Sika's EcoSmart Roof provides you with a roofing option that’s sustainable and good for your wallet. The EcoSmart Roof utilizes the Sarnafil® PVC membrane, Styrofoam™ Brand extruded polystyrene insulation from DuPont, and a gypsum roof board to produce one of the longest lasting, most sustainable responsible roofing systems available.

Below are some of the reasons why an EcoSmart roofing system might be the best fit for your project.

EcoSmart System Benefits:
  • Proven Sarnafil membrane and Styrofoam™ Brand insulation
  • Limited 50 year reuse warranty 
  • The warranty is transferrable
  • Membrane “take back” recycle program at end of life
  • Moisture resistant insulation
  • Fast and easy installation
  • Best for low slope applications
  • Sarnafil membrane has 10% recycled content
  • Good for your wallet
Resistant to Moisture

Styrofoam™ Brand Square Edge Extruded Polystyrene Insulation from DuPont provides the insulating properties necessary to minimize heat flow through the roofing system. This reduces heating and cooling energy consumption, with the added benefit of being reusable when your building is re-roofed. Extruded polystyrene’s ability to resist moisture, which can occur in a roof assembly due to vapor drive and other sources, allows DuPont to provide a 50-year reuse warranty, which is transferrable, on its Square Edge insulation. This means that the building owner can leave the insulation in place when the building is ready for a new roof. (*1) 

The roof board is a highly mold resistant roof panel that consists of a moisture-resistant, noncombustible core of specially treated gypsum with glass mat facings. This roof board improves the fire resistance and wind uplift characteristics of the roofing system, with the added benefit of providing increased resistance to foot traffic to protect the overall roofing system and enhance its longevity.

Recycled Content:  Sarnafil Membrane:  10%  recycled content.(*2)
Recyclable: Installation: Sika will take back old vinyl membranes to be recycled into new roofing membrane products from any location in the continental U.S. (*3)
End of Life: Sika will take back old vinyl membranes to be recycled into new roofing membrane products from any location in the continental U.S. (*3)
Reusable: Styrofoam™ Brand Square Edge insulation is available with a 50-year reuse warranty that is transferrable.  
Energy Efficient: A well insulated roofing system with a reflective roof membrane reduces building energy consumption for heating and cooling and reduces its carbon footprint. Sarnafil membranes meet the cool roof requirements of LEED®, Green Globes® and California Title 24.
Improved Air Quality: When replaced with a reflective membrane, each square meter of dark colored roof could reduce CO2 emissions by up to 3 kg per year. (*4)  
Low Life Cycle Cost: Sika roofing systems have a proven track record of long-term performance, resulting in low life cycle costs.  According to the Athena Institute and the British Board of Agrément, “All available evidence suggests that the durability of Sarnafil membranes when used in accordance with the relevant BBA Certificates should have a life in excess of 35 years.” (*5)
