In order to convert to a value of thermal conductivity (R value), refer to the full report.
For board instulation products # high and low density board - all data are entered in the model on a weight basis. However, even if the materials have the same weight, the final products have a different density which leads to different thermal conductivity and R values of the insulation materials. Also, from a usage standpoint, the board materials are commercialized on an area basis, and their installation in a building is also based on the area (not the weight).
Thus, the reasonable unit system for the functional unit is the #area#, and to comply with the international standards, the chosen functional unit for board products is as follows:
#One meter squared (1 m2) of 3-inch thick board insulation product at a specified R value #
Loose fill is commercialized on a weight basis. The functional unit for that product is as follows:
#One kilogram (1 kg) of loose fill#165The geographical coverage for the production of the rock and slag products studied is North America (the USA and Canada). NAIMA members providing primary data for the study were located in Texas, Alabama, Indiana, Minnesota and Ontario (Canada).The technology is the current technology used at the manufacturing plants. The current methods are described by NAIMA published guidelines, Construction Specifications Institute (CSI), Insulation Contractors Association of America (ICAA) and the National insulation Association (NIA). A complete list of these standards is beyond the scope of this study. In the study site-specific data representative of current technology used in North America, in reference year 2007, were collected and analyzed. In cases when no primary data were available, either estimations provided by the involved companies or calculated data were used.
The primary equipment used in production is referred to as a "Coke melter". Coke is the fuel used.Insulation of buildings.
This product is one of three common products in the rock wool and slag wool industry:
1. Light Density Board (LDB) that is used to provide thermal and acoustical insulation;
2. High density Board (HDB) that is used to provide thermal and acoustical insulation, as well as having the properties of compressive strength and fire resistance; and
3. Loose wool that is used in other insulating applications.Construction_US_NAIMA_Insulation_SpecificationsConstruction_US_NAIMA_Rockwool_ProcessDiagramAlegbraic. N/ALCI resultAttributionalNone.Allocation - massMember companies used mass allocation to report data, when several products were manufactured at the same plant. With respect to background data (energy and materials):
Energy data (e.g. refinery products like diesel, gasoline, fuel oil, and propane) are allocated by mass in relation to the refinery emissions and energy demands are allocated by energy content in relation to the crude oil consumption.
Materials and chemicals needed during manufacturing are modeled using economic allocation when multiple products are manufactured by the respective processes. Where appropriate, the use of waste material (either recycled or collected from other sites) as input to this process will be considered as a burden free material (if coming from another site, transportation will be considered). This is consistent with all LCA guidance documentation in ISO 14040.Data for all upstream materials, electricity, and energy carriers were obtained from the GaBi 4 database 2006. The emissions (CO2, etc.) due to the use of electricity and gasoline (for transport) are accounted for with the use of the database process.
Emissions associated with transportation were determined by capturing the logistical operations of member companies (data collected from the companies for the reference year). Energy use and the associated emissions were calculated using pre-configured transportation models from the GaBi 4 database 2006.The cut-off criteria for including or excluding materials, energy and emissions data of the study are as follows:
? Mass # If a flow is less than 2% of the cumulative mass of the model it may be excluded, providing its environmental relevance is not a concern.
? Energy # If a flow is less than 2% of the cumulative energy of the model it may be 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 will be included. Material flows which leave the system (emissions) and whose environmental impact is greater than 2% of the whole impact of an impact category that has been considered in the assessment must be covered. This judgment will be done based on experience and documented as necessary.Burden-free slag
No outbound transportPEA 2010 - Life Cycle Assessment of Rock & Slag Insulation Products, Final Report95.0It is extremely difficult to estimate the coverage of this study based on production volume with complete accuracy. Sales volume data is typically guarded by manufacturers, as is their own internal estimation of market penetration. The mineral wool production volume in the United States was estimated based only on the total revenue of the industry in the 2002 economic census , so a simple conversion using the production mass provided by participants was not possible. In consultation with NAIMA, it was determined that five of the nine known mineral wool producers in North America were included in this study, and that the largest producers were all included in the study.
# Aislantes Minerales, S.A. de C.V.
# Amerrock Products LP
# Fibrex Insulations, Inc.
# Industrial Insulation Group, LLC
# Isolatek International
# Rock Wool Manufacturing Co.
# Roxul Inc.
# Thermafiber, Inc.
# USG Interiors Inc.
Based on this assessment, and a rough knowledge of the relative size of these producers, it is believed that as much as 70% of the mineral wool production market is represented in this study.Calendar year 2007None.This aggregate process dataset does not include outbound transport from the producer to the consumer.
Although the report associated with this dataset does include outbound transport, use and end of life, this dataset includes only cradle-to-gate.
No outbound transport is included in the model.No statementNorth American Insulation Manufacturers Association (NAIMA)Life Cycle Assessment of Rock & Slag Insulation ProductsThe Goal of the study is to evaluate a cradle to gate Life Cycle Assessment of representative insulation systems, with the intent of publicly distributing the LCI information developed herein to current users of this data in the building and construction industry. The results of the study are intended for public distribution as part of a greater effort to clarify the environmental profile of rock and slag wool insulation products at a time when other potential insulation materials are competing for an environmental advantage in the market. The intended audience for this information is the building and construction technical community, however it is likely that consumer-level communications (like those described above in the Background of the study) will emerge over time as well.
The study evaluates the environmental impacts of three products, as follows:
1. Light Density Board (LDB) that is used to provide thermal and acoustical insulation;
2. High density Board (HDB) that is used to provide thermal and acoustical insulation, as well as having the properties of compressive strength and fire resistance; and
3. Loose wool that is used in other insulating applications.thinkstep2019-02-01T00:00:00.000ILCD format 1.12019-02-01T00:00:00.00000.00.001Data set finalised; entirely publishedNorth American Insulation Manufacturers Association (NAIMA)trueOtherGaBi (source code, database including extension modules and single data sets, documentation) remains property of thinkstep AG. thinkstep AG delivers GaBi licenses comprising data storage medium and manual as ordered by the customer.
