Life Cycle Analysis Supports Energy Saving Benefits of Polyiso Insulation

May 24th, 2012

Polyiso insulation has benefits for project teams seeking Life Cycle Analysis data for building owners that are demanding scientific verification of a manufacturer’s green product claims.

Bayer MaterialScience researchers had the foresight to document the verifiable sustainable attributes of polyiso insulation by conducting a complete and thorough life cycle assessment.

According to Bayer’s press release about a recently released paper documenting the study, their research, “ explores the value of increasing the level of polyiso insulation beyond current building code. In addition to energy and environmental benefits, doing this also offers financial advantages due to the cost savings accumulated over the insulation life cycle.”

The study concluded that increased levels of polyisocyanurate (polyiso) insulation save energy and prevent Global Warming Potential (GWP) emissions during polyiso insulation’s service life that far outweigh energy and GWP emissions associated with the use of polyiso insulation. The study covered the extraction of raw materials, manufacturing, transporting, installing, maintaining and reintegrating of polyiso insulation’s ingredients into new products or reuse of the insulation.

Since conservation of energy is one of the primary reasons for insulating a structure for occupation, the LCA focused on embodied energy of polyiso insulation. Electric power plants in the United States consume fossil fuels, nuclear energy and renewable energy sources to generate electricity.

Atlas Roofing polyiso insulation products provides a high return on investment during the life cycle of a building especially when the embodied energy -- energy needed to make the product and install it in a building project -- is compared to the energy saved by the product over the life of the building (approx. 60-70 years) the pay back is outstanding and adds tremendously to the property value of the structure.

Polyiso foam plastic insulation has the many features for long-term performance that can be conveniently calculated using the EnergyWise Roofing Calculator developed by the National Roofing Contractors Association (NRCA) and the Polyiso Insulation Manufacturers Association (PIMA).

Polyiso is one of the nation’s most widely used and cost-effective insulation products and has been cited by the U.S. Environmental Protection Agency for its responsible impact on the environment.

Polyiso is a closed-cell, rigid foam board insulation used primarily on the roofs of offices, health facilities, warehouses, retail and industrial manufacturing facilities and educational institutions.

For residential applications, homebuilders trying to meet strict energy codes and green building rating systems often select polyiso due to its high thermal performance.

Polyiso is one of the most widely used and cost-effective insulation products with the highest R-value per inch of thickness.

Atlas Roofing Corporation’s polyiso insulation carry the PIMA QualityMark label for its Long Term R-Value (LTTR).  The products have recycled content, zero ozone depletion potential and virtually no global warming potential.
