Product description

Commercial manufactures asphalt-base or bituminous, multi-layer, low-slope, commercial roof systems. Roof systems may consist of one or multiple materials depending on desired performance, warranty, and cost. Roof systems, at minimum include a base sheet and a cap sheets. Most base sheets can also be installed as interply layers . CertainTeed offers over forty roll good products, which equates to hundreds of system configurations and specification options. This EPD is specific to the SBS-Modified Asphalt Roofing (Torch Applied) products. SBS-modified asphalt products are manufactured with styrene-butadiene-styrene infused asphalt which increases flexibility, especially in low temperatures. Reinforcement mats serve as the structure to bituminous low-slope roll goods. The mats are impregnated and coated with SBS-modified asphalt. Products are available with either fiberglass or polyester reinforcement which can vary in thickness and weight. Fiberglass stands up well to heat and tension. Its inherently high melting point affords superior fire resistance when combined with a fire-retardant asphalt formulation. Fiberglass-reinforced products applied in hot asphalt retain excellent dimensional stability. When combined with SBS-modified asphalt, the sheets will resist roof movement until the stress absorbed in the mat forces a break. Polyester’s predominant benefits are puncture resistance and high elongation. Polyester products handle rooftop foot traffic better. They can also cyclically absorb the strain of building movement and return back to their original dimension.

Interpretation

Based on the results of the life cycle assessment, the life cycle impacts are strongly driven by the raw materials and installation phases. Within the raw materials, the mats and coatings, and where included, the fire retardant metals, contributed significantly to the environmental impact potentials. Installation methods vary among the products in the study and installation for specific projects varies widely depending on the project, products used, applications, etc. This makes specific installation data difficult to obtain. Due to the variable nature of the installation methods and materials, the results for the installation phase of the life cycle should be considered highly uncertain. The results for individual products within each of the product lines specified in this study vary slightly compared to the averages reported in this EPD, typically due to the coatings and presence of fire retardant metals in the raw material composition. The results for the each individual product included in the average are reported in the appendix of this EPD.

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.
