Product description

Product Identification:

Fiberglass batt insulation is a rigid, bonded blanket insulation produced in a range of R-values (thermal resistance). Fiberglass is inorganic and noncombustible. It is made from molten glass and spun or blown into fibers that are then processed into the final product, available in both faced and unfaced varieties. The fibers will not rot or absorb moisture and do not support the growth of mildew, mold, or fungus.

The following fiberglass batt products are covered by this environmental product declaration:

• Unfaced Fiberglass.

Product Specification:

Fiberglass batt insulation is an effective insulation that meets the requirements of ASTM C665 –Fiberglass Batts Thermal Insulation. The batts are installed to insulate floors, walls, ceilings, and attic areas. Batts come with or without facing. The batts can be easily placed and cut, trimmed and shaped to fit small or irregular spaces. The batts are made to be easily installed by pressure fitting between framing, with no fastening required.

Interpretation

The manufacturing stage dominates the majority of impact categories due to the energy required by the melting and finishing stages. Raw materials are the second largest contributor due to upstream burdens in material extraction. Together, manufacturing (A3) and Raw Materials (A1) represent nearly 90% of impacts. Therefore, these are the two most effective areas for focusing environmental improvements.

While installation (A5) incurs minimal resources, it is the point at which there is 10% product loss and this impact is most noticeable for Eutrophication with a 7% contribution. End of Life disposal (C4) has contributions of 3-4% in acidification, eutrophication and smog formation. Outbound transport is a minor contributor. There is no impact associated with the use stage. While insulation can influence building energy performance, this aspect is outside the scope of this study. Additionally, it is assumed that insulation does not require any maintenance to achieve its reference service life, which is modeled as being equal to that of the building (i.e., 75 years). No replacements are necessary; therefore, results represent the production of one (1) square meter of insulation at a thickness defined by the PCR functional unit.

At end-of-life, insulation is removed from the building and landfilled. Waste was dominated by the end-of-life disposal of the product. Non-hazardous waste also accounts for waste generated during manufacturing and installation. Impact assessment and other results are shown for a Cradle to gate, with modules A1-A5 and C1-C4 included system boundary. Modules C1 and C3 are not associated with any impact and are therefore declared as zero.

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.
