Product description
Mineral wool insulation is used to promote energy efficiency and comes in a variety of forms and sizes. It resists mold, fungi and bacteria growth, offers protection again moisture infiltration and is not corrosive and contains no chemicals that can degrade pipes and wires.
Mineral board materials are used in: curtain walls, commercial roofs, basement walls, floor over unheated or open spaces and other building envelope applications. Further, the greater density of mineral wool insulation allows the materials to achieve higher R-values and insulating power. This results in increased year-round comfort and significant energy savings.
The fibrous composition of mineral wool insulation provides a flexibility and versatility not found in most other insulations. Mineral wool batt and board insulation comes in a wide variety of densities, sizes, and thicknesses with applications including but not limited to:
- Residential (thermal, acoustical, foundation drainage systems).
- Commercial (thermal, fire stopping and containment, and acoustical applications).
- Industrial (thermal, fire stopping and containment, acoustical, emissions control, pipe and mechanical systems, fillers).
This EPD covers Johns Manville light density mineral wool insulation board products; that is, those mineral wool insulation boards with a density less than or equal to 2.5 pounds per cubic foot (PCF).
Interpretation
For light density mineral wool insulation products analyzed in this study raw material supply (A1), raw material transport (A2), manufacturing (A3) contributed 40% to 95% of all potential impacts. Transportation of products to installation was most significant for smog formation potential (SFP) and abiotic depletion potential (ADP) Fossil. Potential environmental impacts from installation and end-of-life for all products were the least significant contributors. For light density mineral wool board insulation products studied the global warming potential impacts were largely due to emissions from electricity and combustion of hard coals and natural gas within the manufacturing process. While this is expected it also gives the largest opportunity of potential with the expansion of green energy in North America. Efficiency or renewable energy improvements made to support the processes of melting, forming or finishing energy would advance continued impact reduction efforts. Reduction in operations downtime would also optimize impact potential. LCA results are based on a relative approach and indicate potential environmental effects therefore do not predict actual impacts on category impacts.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
