Life Cycle Benefits of SIPs

When choosing R-Control SIP Panels you are getting a material with built-in features that provide environmental benefits. Building materials and their impact on the environment should be considered over the full life of the building structure. This is considered the “life cycle” of the building. This includes inventorying the cost to the environment from material production, transportation, installation, use, and end of life reuse, recycling, or disposal. Research has shown that for both residential buildings and commercial buildings that operations contribute to over 90% of the building’s impact on global warming. Reducing energy use is the best way to reduce our impact on the environment.

Assessment Study.

The Expanded Polystyrene Molders Association (EPSMA) commissioned industry leading Franklin Associates to conduct a life cycle assessment of SIPs with EPS insulation. The study quantified the energy use and emissions associated with SIP production and compares this with the savings in energy and greenhouse gas that result from the use of SIPs compared to stick framed construction. The life cycle stages evaluated include: all steps in the production of R-Control SIPs with EPS insulation from raw material extraction, through manufacturing, shipment to the project site and finally electricity and natural gas consumption for heating and cooling of the building over its 50 year life use.


Energy and greenhouse gas savings are determined by comparing the heating and cooling energy requirements for a typical stick framed house to the same house built with R-Control SIPs. The typical stick framed house is 2×6 wood frame construction with R-19 fiberglass insulation.

SIP Energy GWP Investment and Payback


Results of the study proved the significant energy savings achieved over the long-term by the use of R-Control SIPs and showed substantial reductions in greenhouse gas emissions.
