The inventory is based on a mix of industry data from the US mills who are members of the Polyisocyanurate Insulation Manufacturer's Association (PIMA). The Funtional Unit is 1 ft2 of installed product.0This LCI represents a production mix within the US.
The geographical coverage of this study is polyiso installation manufacturing and distribution in North America. Special efforts were made to obtain data from North American-based operations. Geographical locations for the key life cycle processes are summarized in Table 3.The manufacture of Polyiso foam board involves the blowing of foam between two parallel layers of facer. The exact mixture of foam components modeled here is a representative mix based on the entire PIMA industry, though each manufacturer will often deviate slightly to acheive specific cost and performance targets.Polyiso foam is used to insulate buildings in wall and roof applications.construction_us_polyiso insulation_plant flow diagram_for_pima.jpgLCI resultAttributionalnoneAllocation - volumeAllocation - other explicit assignmentThe cut-off criteria for the study include or exclude materials, energy and emissions data as follows:
# Mass # If a flow is less than 1% of the cumulative mass of the model it is excluded, providing its environmental relevance is not a concern.
# Energy # If a flow is less than 1% of the cumulative energy of the model it is excluded, providing its environmental relevance is not a concern.
# Environmental relevance # If a flow meets the above criteria for exclusion, yet is thought to potentially have a significant environmental impact, it is included. This judgment will be done based on experience and documented as necessary.
The sum of the excluded material flows do not exceed 5% of mass, energy or environmental relevance.NAIMA 2011 - Life Cycle Assessment of Polyiso Insulation95.0The market share for raw materials was factored into the modeling by reported production rates. For example, the polyol dataset was averaged from three companies' data. Each complete LCI was scaled down to represent that company's share of the market based on each of the three reported annual production volumes.Full year, 2008The data set represents a cradle to gate dataset.
