In addition, primary data was collected from all three polyeser polyol plants in the US. Polyisocyanurate (Polyiso) is a closed-cell, rigid foam board insulation consisting of a foam core sandwiched between two facers. The foam core is composed of closed-cell rigid Polyiso foam produced through the chemical reaction of an “A” side (MDI) and a “B” side (polyester polyol with various additives such as catalysts, surfactants, and flame retardant) plus a blowing agent (pentane). For wall applications, the most common facer is a lamination of aluminum foil over kraft paper.
The major raw materials at a Polyiso insulation manufacturing plant consist of chemical liquids stored in tanks onsite. The chemicals for the “A” side (MDI), the “B” side (polyester polyol plus catalysts, surfactants, and flame retardants) and the blowing agent (pentane) are pumped from storage into process tanks. The “B” side and blowing agent are then pumped to a mixer and then to a mix head where they are combined with the “A” side and injected between the top and bottom facers on the pour table. These chemicals combine on the pour table and react rapidly to form a closed cell foam board that is sandwiched between the top and bottom facers. The rigid foam board then travels within a heated laminator on moving conveyor belts, which aids in cell formation and hardens the board. The board then exits the laminator and is fed through saws that trim the board to the desired width and then through a crosscut saw that cuts the board into desired lengths. The finished rigid boards are then staked, packaged with plastic wrap, labeled, and moved via fork truck to a warehouse area for storage and eventual loading onto trucks for shipment.Tris(2-chloroisopropyl)phosphate (TCPP)Thermal energy from natural gasTap water from groundwaterTruck - Trailer, basic enclosed / 45,000 lb payload - 8bFoil FacerPolyethylene film (LDPE/PE-LD)Methylene Diphenyl Diisocyanate (MDI)Diesel mix at filling stationNon-ionic surfactant (fatty acid derivate)Rigid cellular Polyiso wall insulation board typically is installed as a continuous insulation in a wide variety of commercial and residential wall assemblies. In light framed wood or metal wall construction, Polyiso typically is attached to the exterior of the wall framing and covered by an exterior finish. In concrete or masonry mass wall construction, Polyiso
is typically attached to the exterior of the inner wall assembly of the cavity and separated by an air space from the outer wall assembly. When masonry is use as the exterior finish in wood or metal framed wall construction, the Polyiso insulation also typically is separated by an air space from the exterior finish.LCI resultAttributionalnoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentAllocation - massDirect land use change: GHG emissions from direct LUC allocated to good/service for 20 years after the LUC occurs.
Carbon storage and delayed emissions: credits associated with temporary (carbon) storage or delayed emissions are not considered in the calculation of the Global Warming Potential impacts for the default impact categories.
Emissions off-setting: not included
Fossil and biogenic carbon emissions and removals: removals and emissions are modelled as follows: All GHG emissions from fossil fuels (including peat and limestone) are modelled consistently with the ILCD list of elementary flows. In the case that the emissions refer to the molecules CO2 and CH4, they are modelled as ‘carbon dioxide (fossil)’ and ‘methane (fossil)’. Biogenic uptake and emissions are modelled separately. For land use change, all carbon emissions and uptakes are inventoried separately for each of the elementary flows. Soil carbon accumulation (uptake) via improved agricultural management is excluded from the model.NoneIf a flow is less than 1% of the cumulative mass of all inputs and outputs of the LCI model, it is excluded, provided its environmental relevance is not a concern. If a flow is less than 1% of the cumulative energy of all inputs and outputs of the LCI model, it is excluded, provided its environmental relevance is not a concern. The sum of all excluded material flows does not exceed 5% of mass, energy, or environmental relevance.Noneary energy and emissions data regarding manufacturing processes were collected through a plantby-plant survey of all PIMA member manufacturing plants in the United States and Canada. The survey was conducted in January 2014 and reported annual values based on 2013 plant operations. In addition to energy use, the survey included information with regard to packaging, scrap/waste, and emissions rates associated with the manufacture of Polyiso roof insulation. In addition to data collected directly from PIMA member manufacturing operations, primary data was collected from the following sources:
• All three polyester polyol plants in the US
• Energy/emissions factors from one facer plant for glass reinforced fiber (GRF) facer
• Energy use for insulation installation on a building
Energy/emissions data from life cycle databases, studies in the literature, etc., were used for all other modeling of raw materials, transportation factors, and land disposal. In all cases, the data collected represented technologies currently in use, and all secondary data was not older than 10 years.NoneFor details please see the document "GaBi Databases Modelling Principles"NoneEnvironmental Product Declaration: Polyiso Wall Insulation Boards95.02014NoneThe data set represents a cradle to gate inventory.
