This declaration is an environmental product declaration (EPD) in accordance with ISO 14025. EPDs rely on Life Cycle Assessment (LCA) to provide information on a number of environmental impacts of products over their life cycle. Exclusions: EPDs do not indicate that any environmental or social performance benchmarks are met, and there may be impacts that they do not encompass. LCAs do not typically address the site-specific environmental impacts of raw material extraction, nor are they meant to assess human health toxicity. EPDs can complement but cannot replace tools and certifications that are designed to address these impacts and/or set performance thresholds – e.g. Type 1 certifications,

health assessments and declarations, environmental impact assessments, etc. Accuracy of Results: EPDs regularly rely on estimations of impacts, and the level of accuracy in estimation of effect differs for any particular product line and reported impact. Comparability: EPDs are not comparative assertions and are either not comparable or have limited comparability when they cover different life cycle stages, are based on different product category rules or are missing relevant environmental impacts. EPDs from different programs may not be comparable.

Product Description and InformationDuPont’s polyisocyanurate rigid foam (ISO foam) insulation features a high-performance closed-cell polyisocyanuratefoam core sandwiched between durable, exterior facers. The facers also create a barrier which minimizes air and vapor transmission. The insulation is designed to deliver energy savings, weatherization protection and other benefits in residential and commercial wall applications. DuPont’s polyisocyanurate rigid foam (ISO foam) insulation is easy toinstall, can be applied to a variety of substrates, satisfies the applicable fire, air and water-resistive barrier requirements, and maintains a consistently high R-value throughout the lifecycle of the building.

DuPont ISO foam insulation products are categorized into two product families: Tuff-R™ and Thermax™. The Tuff-R™ products are primarily, but not exclusively, used in residential applications. The Tuff-R™ products consist of polyisocyanurate foam, faced with trilaminate facers made up of foil, Kraft paper, and polyester films.

Thermax™ products are primarily but not exclusively used in commercial buildings and can be left exposed to the interior of those buildings after installation because of their resistance to fire. The product consists of trimer foam, faced with aluminum foil at different thicknesses. Thermax™ and most Tuff-R™ products have glass fiber in the foam core that improves fire resistance.

Table 1 lists each ISO foam product.

Life Cycle Assessment – Product System and Modeling

Functional UnitThe functional unit of the product as defined by the PCR is 1 square meter of insulation material with a thickness thatgives an average thermal resistance (RSI) RSI=1 m2K/W (5.68h·ft2·°F/Btu) and with a building service life of 60 years.The calculated thickness which provides the required RSI value for both Tuff-R™ and Thermax™ families is 22.2mm.

Life Cycle Stages AssessedThe ISO foam insulation study was a cradle-to-grave analysis, so the boundaries extended upstream to materials in the earth and continued to the commercial product going to landfill. The use phase is excluded in this study. The life cycle stages assessed in this study include:• Raw material production including extraction of primary raw

materials, raw material manufacturing, and disposal of key raw material production waste

• All raw material transportation to manufacturing location• ISO foam production, including the Pennsauken facility primary

utilities and emissions data• Facer production• Packaging of product• Disposal of manufacturing waste• Commercial product transportation from plant to distributor• Commercial product transportation from distributor to

building site• Commercial product transportation from building site

to landfill• Landfill of used product

AssumptionsThe following assumptions were made for this life cycle assessment:• Products are disposed of in a landfill at the end of life• Installation requires no external energy input and no

maintenance• Blowing agent is released to the atmosphere during the

60 year study• Transportation of the product from the distributor to the

building site is assumed to be 50 miles by truck• Transportation of the product from the building site to landfill

is assumed to be 100 miles by truck• During its service life, insulation significantly reduces the

energy use in a building, thereby reducing the impact on the environment. However, building heating and cooling is excluded during the use phase of the life cycle assessment as required by the PCR. The benefits of insulation in the reduction of building energy use is described separately in this declaration as additional information beyond the scope of the product life cycle assessment.

• Dismantling and demolition were not considered during the end of life stage.

Cut-Off CriteriaCut-off criteria are conditions that specify how much of the data obtained in the study will be used in modeling the system. For an extremely detailed life cycle inventory, accounting for every input is likely to be impractical within reasonable time constraints; hence, cut-off criteria help guide the rationale for excluding any data. According to the PCR, a process or activity that contributes no more than 2% of the total mass and uses no more than 1% of the total energy may be omitted from the inventory analysis. An exception is that omissions of any material flows that may have a relevant contribution to the selected impact categories of the products underlying the Environmental Product Declaration will be justified, if applicable, by a sensitivity analysis. The sum of the excluded material flows must not exceed 5% of mass, energy or environmental relevance.

To provide a robust analysis, and to thereby enhance the credibility of the study, the approach taken was to include as much of the life cycle inventory data in the models as possible. All known inputs to ISO foam production have been included. The implicit cut-off for this data source is relevance: inputs and outputs related directly to the foam production operation are included; ancillary inputs (office supplies and travel, for example) are not included. Capital production process items (machines, equipment etc) were excluded from this study.

This EPD is in compliance with the cut-off criteria. No processes were neglected or excluded.

TransportationTransportation was included for all inbound raw materials, shipment of commercial product to distributor, shipmentfrom distributor to building site, and end of life product to landfill. The raw material transport were categorized as being less than 1000 miles or between 1000 miles and 2000 miles by either rail or truck. Actual distances were used in the life cycle assesment. Transportation of the product from the distributor to the building site is assumed to be 50 miles by truck. Transportation of the product from the building site to landfill is assumed to be 100 miles by truck.

Period Under ConsiderationAll DuPont primary data for the production used in the study were from the year of 2012.

Secondary Background DataAll DuPont primary data for the energy and material inputs and emissions during production was collected internally fromDuPont facilities. The data was used for the energy and material inputs and emissions during production. Ecoinvent was the standard reference for library LCA data.

Data QualityOverall, the data used in this study, a combination of DuPont production data and Ecoinvent library data, allowed the construction of life cycle models that describe the production of ISO foam insulation. Primary data was obtained for the most critical inputs – MDI production and ISO foam production in Pennsauken. This is high quality data since it comes directly from DuPont facilities. Secondary data, from Ecoinvent 2.2 was used for upstream process models to provide an established, documented and reasonable source of information. Stoichiometric models for flame retardants and catalysts were developed to increase accuracy of the study.

AllocationIn a production process where more than one type of product is generated, it is necessary to allocate the environmental impacts (inputs and outputs) from the process to the different products in order to obtain product-based inventory data. Allocation rules should reflect the goal of the production process. For production of building envelope thermal insulation products, allocation is preferably carried out according to mass. This was used in this project to divide utilities use and emissions known on an annual basis across all production of the plant. Different specific ISO foam products are manufactured at the plant. All carried the same direct manufacturing burdens per unit mass.

UseThermax™ and Tuff-R™ foam insulation do not require any additional resources to perform its intended use as a thermal insulator. Ancilliary materials may be needed to satisfy requirements as an air, water or fire resistive assembly, but they have not been included in the analysis. During use, there are reductions in the energy consumption of a building and also the release of the blowing agent. For the purposes of this study all ablowing agent is assumed to be released at disposal at the end of the modeled time period of 60 years.

End-of-LifeFor the purposes of this study the end of life stage for ISO foam is disposal to a landfill. The transportation of the foam boards from building site to landfill is considered to be 100 miles.

As shown in the pie chart, the majority of the primary energy demand is attributed to the Raw Materials stage, with 92% of the contribution. Due to its function as a thermal insulator and the insulation product not requiring any energy durinng use, great reductions in energy consumption of a building are achieved during the use phase of the polyiso insulation.

Building Use Stage BenefitsInsulation requires no extra energy or utilities to operate over its useful life. The polyisocyanurate insulation reduces the energy associated with heating and cooling the building, and contributes to reduction in greenhouse gas emissions.

An example presented below provides the net energy savings for average rigid polyisocyanurate insulation in a medical office building. The net energy saved is the total energy saved minus the life cycle energy for production and disposal of rigid polystyrene insulation.

The case study used for the analysis is a two story medical office building 21,335 square foot insulated to ASHRAE 90.1 2013 minimum R-value requirements for walls and roofs. The condi-tioned space within the building is 20836 sq ft. The wall insulated area is 10,003 square feet . The roof insulated area is11,493 square feet. The example includes an analysis of a mass wall frame structure and a steel wall frame structure for four locations: Dallas, TX, Nashville, TN, Saginaw, MI, Minneapolis, MN all in four different ASHRAE Zones. The modeling was performed using EnergyPlus, an hourly energy analysis simulation program. This actual medical office building is located in Saginaw, MI and thebuilding was modeled with the appropriate HVAC equipment necessary.

In comparison to the case study presented below an office building not used for medical purposes would have a fasterpayback due to the mechanical system needed. Additionaly, buildings insulated to ASHRAE 90.1-2010 or 2007 would also have a faster payback due to less insulation being required. This case study building has an energy savings payback ranging from 2 years in a cold climate (Zone 5 and 6) to 3.8 years in a warm climate (Zone 3).

The polyisocyanurate foam has a low global warming potential, therefore the payback time for the greenhouse gas avoidance ranges from 0.8 to 1.6 years depending on the location of the building. USEPA eGRID Version 9.0 was used to determine CO2 equivalent numbers due to electricity. The natural gas conversion was determined based on the USEPA Greenhouse Gas Equivalent Calculator.
