Roofing systems from Sika are ideally suited to fulfill the Congressional requirements of U.S. government procurement agencies — under established directives to incorporate energy efficiency and sustainability into all facets of building construction.

Sika Sarnafil Roofing Solutions are Compliant with:

  • Department of Defense Unified Facilities Criteria
  • U.S. Postal Service Building Design Standards
  • EnergyStar, LEED & Green Globes

Energy Efficiency

Buildings consume 40 percent of primary energy and 72 percent of the electricity in the U.S. Total energy expenditures for federal government facilities alone were $4.26 billion in 2005. A large percentage of that energy usage is to cool buildings. Even in colder climates, many buildings are air conditioned year- round due to internal heat.

Greenhouse Gas, Pollution, and Urban Heat Island Mitigation

Carbon dioxide emissions are a major contributor to global warming. Buildings account for 35 percent of the emissions in the U.S. Replacing dark colored roofs with reflective, light colored roofs on 80 percent of commercial buildings air conditioned roof areas could reduce the carbon dioxide emissions by 6.23 metric tons per year.

Sustainable Solutions

EnergySmart Roof

Sika EnergySmart Roof helps minimize the urban heat island effect caused in large part by a high density of dark colored surfaces in and urban environment.

Recycling Program

Recycling reduces the environmental impacts of producing new materials at the beginning of the life cycle and the burden on landfills at the end.

Sika recycles more that 4 million pounds of membrane trimmings annually. In addition, a post-consumer recycling program allows building owners to recycle vinyl roofs at the end of their useful life. Millions of square feet of old roofing membrane have been recycled into new roofing products.

Solar Roofs

The Solar Electric Roofing System integrates reflective EnergySmart Roof which improves the building’s energy efficiency and reduces utility bills. Building owners save money, especially during peak demand periods, and may get credit for feeding excess solar power into the local electrical grid.

Green Roofs

Green roofs are healthy, sustainable and regenerative roof landscapes beneficial to the surrounding environment. Sika has been waterproofing green roofs for more than 35 years.

Durability and Longevity

Sika Sarnafil roofs last for decades. Independent scientific research organizations have evaluated and documented this performance:

An independent panel consisting of industry consultants and government-related organizations from the U.S. and Canada studied the service life of roofing membranes. The group issued an interim report in 2005 indicating that Sika's composite score was excellent, and that the company’s membranes performed well in virtually all categories.

Superior Fire Performance

Vinyl by its basic formulation is very fire resistant. This is why PVC is utilized in many critical applications such as electrical wire jackets. One of the strengths of PVC roofing membranes is the ability to self extinguish and resist spread of flame. Sika Sarnafil’s roofing membranes have been widely tested and meet fire code requirements in over 20 countries worldwide.

Life Cycle Analysis

Carbotech, a leading European consulting firm, performed a comparative life cycle analysis of the most widely used low-slope roofing system. The Sika Sarnafil membrane received the highest rating.
